This paper also validates and demonstrates the proposed programmability and virtualization capabilities of the PORVIR-5G through demonstrations, thereby enabling the key performance demands of 5G networks.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('118','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_118\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/link.springer.com\/article\/10.1007\/s12243-025-01136-7\" title=\"https:\/\/link.springer.com\/article\/10.1007\/s12243-025-01136-7\" target=\"_blank\">https:\/\/link.springer.com\/article\/10.1007\/s12243-025-01136-7<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1007\/s12243-025-01136-7\" title=\"Follow DOI:10.1007\/s12243-025-01136-7\" target=\"_blank\">doi:10.1007\/s12243-025-01136-7<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('118','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Maiko Andrade, Juliano Araujo Wickboldt<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('117','tp_links')\" style=\"cursor:pointer;\">A Study on 5G Network Slice Isolation Based on Native Cloud and Edge Computing Tools<\/a> <span class=\"tp_pub_type article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_journal\">Journal of Network and Systems Management (JNSM), <\/span><span class=\"tp_pub_additional_volume\">33 <\/span><span class=\"tp_pub_additional_number\">(90), <\/span><span class=\"tp_pub_additional_year\">2025<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 1573-7705<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_117\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('117','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_117\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('117','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_117\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('117','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=28#tppubs\" title=\"Show all publications which have a relationship to this tag\">5G<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=27#tppubs\" title=\"Show all publications which have a relationship to this tag\">Cloud Computing<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=90#tppubs\" title=\"Show all publications which have a relationship to this tag\">Fog &amp; Edge Computing<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=49#tppubs\" title=\"Show all publications which have a relationship to this tag\">Network Virtualization &amp; Slicing<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_117\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@article{journals\/jnsm\/Andrade5GSlice25,<br \/>\r\ntitle = {A Study on 5G Network Slice Isolation Based on Native Cloud and Edge Computing Tools},<br \/>\r\nauthor = {Maiko Andrade and Juliano Araujo Wickboldt},<br \/>\r\nurl = {https:\/\/link.springer.com\/article\/10.1007\/s10922-025-09958-5},<br \/>\r\ndoi = {10.1007\/s10922-025-09958-5},<br \/>\r\nissn = {1573-7705},<br \/>\r\nyear  = {2025},<br \/>\r\ndate = {2025-07-09},<br \/>\r\nurldate = {2025-07-09},<br \/>\r\njournal = {Journal of Network and Systems Management (JNSM)},<br \/>\r\nvolume = {33},<br \/>\r\nnumber = {90},<br \/>\r\nabstract = {5G networks support various advanced applications through network slicing, network function virtualization (NFV), and edge computing, ensuring low latency and service isolation.

The paper details the key architectural components, behaviours, and interfaces to meet industry needs and provides a proof of concept demonstrating the framework\u2019s capabilities.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('115','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_115\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S187705092500506X\" title=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S187705092500506X\" target=\"_blank\">https:\/\/www.sciencedirect.com\/science\/article\/pii\/S187705092500506X<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1016\/j.procs.2025.02.149\" title=\"Follow DOI:10.1016\/j.procs.2025.02.149\" target=\"_blank\">doi:10.1016\/j.procs.2025.02.149<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('115','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Alexandre Gustavo Wermann, Juliano Araujo Wickboldt<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('109','tp_links')\" style=\"cursor:pointer;\">KTWIN: A serverless Kubernetes-based Digital Twin platform<\/a> <span class=\"tp_pub_type article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_journal\">Computer Networks, <\/span><span class=\"tp_pub_additional_volume\">259 <\/span>, <span class=\"tp_pub_additional_pages\">pp. 111095, <\/span><span class=\"tp_pub_additional_year\">2025<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 1389-1286<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_109\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('109','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_109\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('109','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_109\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('109','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=27#tppubs\" title=\"Show all publications which have a relationship to this tag\">Cloud Computing<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=86#tppubs\" title=\"Show all publications which have a relationship to this tag\">Digital Twin<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=90#tppubs\" title=\"Show all publications which have a relationship to this tag\">Fog &amp; Edge Computing<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_109\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@article{journal\/comnet\/Wermann25,<br \/>\r\ntitle = {KTWIN: A serverless Kubernetes-based Digital Twin platform},<br \/>\r\nauthor = {Alexandre Gustavo Wermann and Juliano Araujo Wickboldt},<br \/>\r\nurl = {https:\/\/www.sciencedirect.com\/science\/article\/pii\/S1389128625000635},<br \/>\r\ndoi = {10.1016\/j.comnet.2025.111095},<br \/>\r\nissn = {1389-1286},<br \/>\r\nyear  = {2025},<br \/>\r\ndate = {2025-02-12},<br \/>\r\njournal = {Computer Networks},<br \/>\r\nvolume = {259},<br \/>\r\npages = {111095},<br \/>\r\nabstract = {Digital Twins (DTs) systems are virtual representations of physical assets allowing organizations to gain insights and improve existing processes.

Among the main results obtained, it was possible to observe that the open source implementation free5GC presents better performance regarding data plane bit rates, while Open5GS shows better stability during the registration process of multiple devices.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('103','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_103\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/ieeexplore.ieee.org\/document\/10154399\" title=\"https:\/\/ieeexplore.ieee.org\/document\/10154399\" target=\"_blank\">https:\/\/ieeexplore.ieee.org\/document\/10154399<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1109\/NOMS56928.2023.10154399\" title=\"Follow DOI:10.1109\/NOMS56928.2023.10154399\" target=\"_blank\">doi:10.1109\/NOMS56928.2023.10154399<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('103','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Rafael de Jesus Martins, Juliano Araujo Wickboldt, Lisandro Zambenedetti Granville<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('101','tp_links')\" style=\"cursor:pointer;\">Assisted Monitoring and Security Provisioning for 5G Microservices-Based Network Slices with SWEETEN<\/a> <span class=\"tp_pub_type article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_journal\">Journal of Network and Systems Management (JNSM), <\/span><span class=\"tp_pub_additional_volume\">31 <\/span><span class=\"tp_pub_additional_number\">(2), <\/span><span class=\"tp_pub_additional_pages\">pp. 36, <\/span><span class=\"tp_pub_additional_year\">2023<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 1573-7705<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_101\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('101','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_101\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('101','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_101\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('101','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=28#tppubs\" title=\"Show all publications which have a relationship to this tag\">5G<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=27#tppubs\" title=\"Show all publications which have a relationship to this tag\">Cloud Computing<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=84#tppubs\" title=\"Show all publications which have a relationship to this tag\">Microservices<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=36#tppubs\" title=\"Show all publications which have a relationship to this tag\">Network Orchestration<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=52#tppubs\" title=\"Show all publications which have a relationship to this tag\">Network Security<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=49#tppubs\" title=\"Show all publications which have a relationship to this tag\">Network Virtualization &amp; Slicing<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_101\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@article{journals\/jnsm\/Martins5GMS23,<br \/>\r\ntitle = {Assisted Monitoring and Security Provisioning for 5G Microservices-Based Network Slices with SWEETEN},<br \/>\r\nauthor = {Rafael de Jesus Martins and Juliano Araujo Wickboldt and Lisandro Zambenedetti Granville},<br \/>\r\nurl = {https:\/\/link.springer.com\/article\/10.1007\/s10922-023-09728-1},<br \/>\r\ndoi = {10.1007\/s10922-023-09728-1},<br \/>\r\nissn = {1573-7705},<br \/>\r\nyear  = {2023},<br \/>\r\ndate = {2023-02-12},<br \/>\r\nurldate = {2023-02-12},<br \/>\r\njournal = {Journal of Network and Systems Management (JNSM)},<br \/>\r\nvolume = {31},<br \/>\r\nnumber = {2},<br \/>\r\npages = {36},<br \/>\r\nabstract = {5G networks have imposed a drastic shift in how mobile telecommunications must operate.

Based on this architecture, a set of experiments are conducted to analyze how the overall system performance is affected by different configuration parameters and varied number of connected clients.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('97','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_97\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-file-pdf\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/wp-content\/uploads\/Analyzing-Federated-Learning-Performance-in-Distributed-Edge-Scenarios-WGRS-2022-Camera-Ready.pdf\" title=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/wp-content\/uploads\/Analyzing-Federated-Lear[...]\" target=\"_blank\">https:\/\/www.inf.ufrgs.br\/~jwickboldt\/wp-content\/uploads\/Analyzing-Federated-Lear[...]<\/a><\/li><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/sol.sbc.org.br\/index.php\/wgrs\/article\/view\/21484\" title=\"https:\/\/sol.sbc.org.br\/index.php\/wgrs\/article\/view\/21484\" target=\"_blank\">https:\/\/sol.sbc.org.br\/index.php\/wgrs\/article\/view\/21484<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.5753\/wgrs.2022.223574\" title=\"Follow DOI:10.5753\/wgrs.2022.223574\" target=\"_blank\">doi:10.5753\/wgrs.2022.223574<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('97','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_inproceedings\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Rafael Antonio Ventura Trevisan, Francisco Paiva Knebel, Juliano Araujo Wickboldt, Mara Abel<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('98','tp_links')\" style=\"cursor:pointer;\">Aquisi\u00e7\u00e3o de Dados Escal\u00e1vel e Ciente da Aplica\u00e7\u00e3o para G\u00eameos Digitais<\/a> <span class=\"tp_pub_type inproceedings\">Inproceedings<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_booktitle\">27\u00ba Workshop de Ger\u00eancia e Opera\u00e7\u00e3o de Redes e Servi\u00e7os, WGRS 2022, Virtual Conference, May 23-27, 2022, <\/span><span class=\"tp_pub_additional_pages\">pp. 57-70, <\/span><span class=\"tp_pub_additional_publisher\">SBC, <\/span><span class=\"tp_pub_additional_year\">2022<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 2595-2722<\/span><span class=\"tp_pub_additional_note\">, (In portuguese, Best paper award)<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_98\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('98','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_98\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('98','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_98\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('98','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=86#tppubs\" title=\"Show all publications which have a relationship to this tag\">Digital Twin<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=53#tppubs\" title=\"Show all publications which have a relationship to this tag\">Internet of Things (IoT)<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_98\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@inproceedings{conf\/wgrs\/Trevisan22,<br \/>\r\ntitle = {Aquisi\u00e7\u00e3o de Dados Escal\u00e1vel e Ciente da Aplica\u00e7\u00e3o para G\u00eameos Digitais},<br \/>\r\nauthor = {Rafael Antonio Ventura Trevisan and Francisco Paiva Knebel and Juliano Araujo Wickboldt and Mara Abel},<br \/>\r\nurl = {https:\/\/www.inf.ufrgs.br\/~jwickboldt\/wp-content\/uploads\/Aquisicao-de-Dados-Escalavel-e-Ciente-da-Aplicacao-para-Gemeos-Digitais-WGRS-2022-Camera-Ready.pdf<br \/>\r\nhttps:\/\/sol.sbc.org.br\/index.php\/wgrs\/article\/view\/21477},<br \/>\r\ndoi = {10.5753\/wgrs.2022.223478},<br \/>\r\nissn = {2595-2722},<br \/>\r\nyear  = {2022},<br \/>\r\ndate = {2022-05-23},<br \/>\r\nurldate = {2022-05-23},<br \/>\r\nbooktitle = {27\u00ba Workshop de Ger\u00eancia e Opera\u00e7\u00e3o de Redes e Servi\u00e7os, WGRS 2022, Virtual Conference, May 23-27, 2022},<br \/>\r\npages = {57-70},<br \/>\r\npublisher = {SBC},<br \/>\r\nabstract = {Digital Twin is the name given to a type of system that has full integration between a physical part and a digital part updated in real time.

Based on a realistic implementation and deployment of Digital Twin software components, it is possible to conclude that the distribution of Digital Twins in a fog computing setup can reduce response times, meeting its real-time application requirements.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('95','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_95\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"ai ai-arxiv\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/arxiv.org\/abs\/2012.06118\" title=\"https:\/\/arxiv.org\/abs\/2012.06118\" target=\"_blank\">https:\/\/arxiv.org\/abs\/2012.06118<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('95','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><h3 class=\"tp_h3\" id=\"tp_h3_2020\">2020<\/h3><div class=\"tp_publication tp_publication_inproceedings\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Rafael Antonio Ventura Trevisan, Francisco Paiva Knebel, Juliano Araujo Wickboldt<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('94','tp_links')\" style=\"cursor:pointer;\">Uma Avalia\u00e7\u00e3o do uso de MQTT para a Implementa\u00e7\u00e3o de Digital Twins<\/a> <span class=\"tp_pub_type inproceedings\">Inproceedings<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_booktitle\">18\u00aa Escola Regional de Redes de Computadores, ERRC 2020, Virtual Conference, November 25-27, 2020, <\/span><span class=\"tp_pub_additional_pages\">pp. 1-7, <\/span><span class=\"tp_pub_additional_publisher\">SBC, <\/span><span class=\"tp_pub_additional_year\">2020<\/span><span class=\"tp_pub_additional_note\">, (in portuguese)<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_94\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('94','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_94\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('94','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_94\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('94','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=86#tppubs\" title=\"Show all publications which have a relationship to this tag\">Digital Twin<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=53#tppubs\" title=\"Show all publications which have a relationship to this tag\">Internet of Things (IoT)<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_94\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@inproceedings{conf\/errc\/Trevisan20,<br \/>\r\ntitle = {Uma Avalia\u00e7\u00e3o do uso de MQTT para a Implementa\u00e7\u00e3o de Digital Twins},<br \/>\r\nauthor = {Rafael Antonio Ventura Trevisan and Francisco Paiva Knebel and Juliano Araujo Wickboldt},<br \/>\r\nurl = {https:\/\/www.inf.ufrgs.br\/~jwickboldt\/wp-content\/uploads\/ERRC2020_Uma_Avalia__o_do_uso_de_MQTT_para_a_Implementa___ICQ3pD9.pdf},<br \/>\r\ndoi = {10.5753\/errc.2020.15187},<br \/>\r\nyear  = {2020},<br \/>\r\ndate = {2020-11-25},<br \/>\r\nbooktitle = {18\u00aa Escola Regional de Redes de Computadores, ERRC 2020, Virtual Conference, November 25-27, 2020},<br \/>\r\npages = {1-7},<br \/>\r\npublisher = {SBC},<br \/>\r\nabstract = {O conceito de Digital Twin tem se tornado cada dia mais importante como um m\u00e9todo para monitorar elementos e prevenir poss\u00edveis defeitos.

This tool was already deployed in Federated Union of Telecommunications Research Facilities for an EU-Brazil Open Laboratory (FUTEBOL) testbeds as part of the control framework and was well validated by the project reviewers and partners.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('93','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_93\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/ieeexplore.ieee.org\/document\/9247110\" title=\"https:\/\/ieeexplore.ieee.org\/document\/9247110\" target=\"_blank\">https:\/\/ieeexplore.ieee.org\/document\/9247110<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1109\/ACCESS.2020.3035619\" title=\"Follow DOI:10.1109\/ACCESS.2020.3035619\" target=\"_blank\">doi:10.1109\/ACCESS.2020.3035619<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('93','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_inproceedings\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Rafael de Jesus Martins, Juliano Araujo Wickboldt, Lisandro Zambenedetti Granville<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('92','tp_links')\" style=\"cursor:pointer;\">SWEETEN: Automated Network Management Provisioning for 5G Microservices-Based Virtual Network Functions<\/a> <span class=\"tp_pub_type inproceedings\">Inproceedings<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_booktitle\">16th International Conference on Network and Service Management, CNSM 2020, Virtual Conference, November 2-6, 2020, <\/span><span class=\"tp_pub_additional_pages\">pp. 1-9, <\/span><span class=\"tp_pub_additional_publisher\">International Federation for Information Processing (IFIP), <\/span><span class=\"tp_pub_additional_address\"> Virtual Conference, <\/span><span class=\"tp_pub_additional_year\">2020<\/span>, <span class=\"tp_pub_additional_isbn\">ISBN: 978-3-903176-31-7<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_92\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('92','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_92\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('92','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_92\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('92','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=28#tppubs\" title=\"Show all publications which have a relationship to this tag\">5G<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=27#tppubs\" title=\"Show all publications which have a relationship to this tag\">Cloud Computing<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=84#tppubs\" title=\"Show all publications which have a relationship to this tag\">Microservices<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=36#tppubs\" title=\"Show all publications which have a relationship to this tag\">Network Orchestration<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=49#tppubs\" title=\"Show all publications which have a relationship to this tag\">Network Virtualization &amp; Slicing<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_92\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@inproceedings{conf\/cnsm\/Martins20,<br \/>\r\ntitle = {SWEETEN: Automated Network Management Provisioning for 5G Microservices-Based Virtual Network Functions},<br \/>\r\nauthor = {Rafael de Jesus Martins and Juliano Araujo Wickboldt and Lisandro Zambenedetti Granville},<br \/>\r\nurl = {http:\/\/dl.ifip.org\/db\/conf\/cnsm\/cnsm2020\/1570662948.pdf},<br \/>\r\nisbn = {978-3-903176-31-7},<br \/>\r\nyear  = {2020},<br \/>\r\ndate = {2020-11-02},<br \/>\r\nbooktitle = {16th International Conference on Network and Service Management, CNSM 2020, Virtual Conference, November 2-6, 2020},<br \/>\r\npages = {1-9},<br \/>\r\npublisher = {International Federation for Information Processing (IFIP)},<br \/>\r\naddress = { Virtual Conference},<br \/>\r\nabstract = {Forthcoming 5G systems promise a myriad of new and improved applications, relying on Network Functions Virtualization (NFV) to realize some of 5G's stringent requirements.

Orchestra is validated through instantiates and migrates VNFCs following the decisions of personalized orchestration algorithms, with a petty impact in the VNFC\u2019s deployment and migration time.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('88','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_88\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/ieeexplore.ieee.org\/document\/9060959\" title=\"https:\/\/ieeexplore.ieee.org\/document\/9060959\" target=\"_blank\">https:\/\/ieeexplore.ieee.org\/document\/9060959<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1109\/JSAC.2020.2986689\" title=\"Follow DOI:10.1109\/JSAC.2020.2986689\" target=\"_blank\">doi:10.1109\/JSAC.2020.2986689<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('88','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Gustavo Bassil Heimovski, Rog\u00e9rio Correa Turchetti, Juliano Araujo Wickboldt, Lisandro Zambenedetti Granville, Elias Proc\u00f3pio Duarte Jr<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('80','tp_links')\" style=\"cursor:pointer;\">FT-Aurora: A highly available IaaS cloud manager based on replication<\/a> <span class=\"tp_pub_type article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_journal\">Elsevier Computer Networks, <\/span><span class=\"tp_pub_additional_volume\">168 <\/span>, <span class=\"tp_pub_additional_pages\">pp. 107041, <\/span><span class=\"tp_pub_additional_year\">2020<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 1389-1286<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_80\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('80','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_80\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('80','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_80\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('80','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=27#tppubs\" title=\"Show all publications which have a relationship to this tag\">Cloud Computing<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=82#tppubs\" title=\"Show all publications which have a relationship to this tag\">Fault Tolerance<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=81#tppubs\" title=\"Show all publications which have a relationship to this tag\">High Availability<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=57#tppubs\" title=\"Show all publications which have a relationship to this tag\">Infrastructure as a Service (IaaS)<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_80\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@article{journal\/cn\/Heimovski20,<br \/>\r\ntitle = {FT-Aurora: A highly available IaaS cloud manager based on replication},<br \/>\r\nauthor = {Gustavo Bassil Heimovski and Rog\u00e9rio Correa Turchetti and Juliano Araujo Wickboldt and Lisandro Zambenedetti Granville and Elias Proc\u00f3pio Duarte Jr},<br \/>\r\nurl = {http:\/\/www.sciencedirect.com\/science\/article\/pii\/S138912861831346X},<br \/>\r\ndoi = {10.1016\/j.comnet.2019.107041},<br \/>\r\nissn = {1389-1286},<br \/>\r\nyear  = {2020},<br \/>\r\ndate = {2020-02-26},<br \/>\r\njournal = {Elsevier Computer Networks},<br \/>\r\nvolume = {168},<br \/>\r\npages = {107041},<br \/>\r\nabstract = {In this work we describe FT-Aurora, a highly available IaaS (Infrastructure as a Service) cloud manager that allows cloud resources to be accessed even if the manager itself crashes.

We also evaluate the benefits of our approach in terms of: (i) The bandwidth requirements for each fine-grained distribution option, (ii) the latency experienced by mobile users for each fine-grained distribution option, and (iii) the total CPU usage of each fine-grained baseband processing function.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('90','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_90\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S1389128619301033\" title=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S1389128619301033\" target=\"_blank\">http:\/\/www.sciencedirect.com\/science\/article\/pii\/S1389128619301033<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1016\/j.comnet.2019.01.021\" title=\"Follow DOI:10.1016\/j.comnet.2019.01.021\" target=\"_blank\">doi:10.1016\/j.comnet.2019.01.021<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('90','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><h3 class=\"tp_h3\" id=\"tp_h3_2018\">2018<\/h3><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Juliano Araujo Wickboldt, Mauricio Quatrin Guerreiro, Lisandro Zambenedetti Granville, Luciano Paschoal Gaspary, Marcos Felipe Schwarz, Chin Guok, Vangelis Chaniotakis, Andrew Lake, John Macauley<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('29','tp_links')\" style=\"cursor:pointer;\">MEICAN: Simplifying DCN Life-Cycle Management from End-User and Operator Perspectives in Inter-Domain Environments<\/a> <span class=\"tp_pub_type article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_journal\">IEEE Communications Magazine, <\/span><span class=\"tp_pub_additional_volume\">56 <\/span><span class=\"tp_pub_additional_number\">(1), <\/span><span class=\"tp_pub_additional_pages\">pp. 179\u2013187, <\/span><span class=\"tp_pub_additional_year\">2018<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 0163-6804<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_29\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('29','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_29\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('29','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_29\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('29','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=38#tppubs\" title=\"Show all publications which have a relationship to this tag\">Dynamic Circuit Networks (DCN)<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=39#tppubs\" title=\"Show all publications which have a relationship to this tag\">Inter-domain Networking<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_29\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@article{DBLP:journals\/cm\/WickboldtGGGSGC18,<br \/>\r\ntitle = {MEICAN: Simplifying DCN Life-Cycle Management from End-User and Operator Perspectives in Inter-Domain Environments},<br \/>\r\nauthor = {Juliano Araujo Wickboldt and Mauricio Quatrin Guerreiro and Lisandro Zambenedetti Granville and Luciano Paschoal Gaspary and Marcos Felipe Schwarz and Chin Guok and Vangelis Chaniotakis and Andrew Lake and John Macauley},<br \/>\r\nurl = {https:\/\/doi.org\/10.1109\/MCOM.2017.1601205},<br \/>\r\ndoi = {10.1109\/MCOM.2017.1601205},<br \/>\r\nissn = {0163-6804},<br \/>\r\nyear  = {2018},<br \/>\r\ndate = {2018-01-01},<br \/>\r\njournal = {IEEE Communications Magazine},<br \/>\r\nvolume = {56},<br \/>\r\nnumber = {1},<br \/>\r\npages = {179--187},<br \/>\r\nabstract = {National research and education networks (NRENs), such as ESnet, G\u00e9ANT, and RNP, currently promote the employment of dynamic circuit networks (DCNs) to improve scientific communications beyond the capabilities of today's Internet.

In this article, we discuss how SDWN can support the development of a flexible, programmable, and sustainable infrastructure for 5G. We also present a case study based on SDWN to perform frequency assignment, interference, and handover control in an H-CRAN environment. Results allow the establishment of a tradeoff between wireless communication capacity gains and signaling overhead added by the employment of SDWN concepts to H-CRAN.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('32','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_32\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/doi.org\/10.1186\/s13174-017-0068-x\" title=\"https:\/\/doi.org\/10.1186\/s13174-017-0068-x\" target=\"_blank\">https:\/\/doi.org\/10.1186\/s13174-017-0068-x<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1186\/s13174-017-0068-x\" title=\"Follow DOI:10.1186\/s13174-017-0068-x\" target=\"_blank\">doi:10.1186\/s13174-017-0068-x<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('32','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Cristian Cleder Machado, Juliano Araujo Wickboldt, Lisandro Zambenedetti Granville, Alberto Egon Schaeffer-Filho<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('33','tp_links')\" style=\"cursor:pointer;\">ARKHAM: An Advanced Refinement toolkit for Handling Service Level Agreements in Software-Defined Networking<\/a> <span class=\"tp_pub_type article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_journal\">Elsevier Journal of Network and Computer Applications, <\/span><span class=\"tp_pub_additional_volume\">90 <\/span>, <span class=\"tp_pub_additional_pages\">pp. 1\u201316, <\/span><span class=\"tp_pub_additional_year\">2017<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 1389-1286<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_33\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('33','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_33\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('33','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_33\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('33','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=47#tppubs\" title=\"Show all publications which have a relationship to this tag\">Policy-Based Network Management (PBNM)<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=48#tppubs\" title=\"Show all publications which have a relationship to this tag\">Quality of Service (QoS)<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=46#tppubs\" title=\"Show all publications which have a relationship to this tag\">Service Level Management<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=44#tppubs\" title=\"Show all publications which have a relationship to this tag\">Softwarized &amp; Programmable Networks<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_33\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@article{DBLP:journals\/jnca\/MachadoWGF17,<br \/>\r\ntitle = {ARKHAM: An Advanced Refinement toolkit for Handling Service Level Agreements in Software-Defined Networking},<br \/>\r\nauthor = {Cristian Cleder Machado and Juliano Araujo Wickboldt and Lisandro Zambenedetti Granville and Alberto Egon Schaeffer-Filho},<br \/>\r\nurl = {https:\/\/doi.org\/10.1016\/j.jnca.2017.04.009},<br \/>\r\ndoi = {10.1016\/j.jnca.2017.04.009},<br \/>\r\nissn = {1389-1286},<br \/>\r\nyear  = {2017},<br \/>\r\ndate = {2017-01-01},<br \/>\r\njournal = {Elsevier Journal of Network and Computer Applications},<br \/>\r\nvolume = {90},<br \/>\r\npages = {1--16},<br \/>\r\nabstract = {Software-Defined Networking (SDN) provides a more sophisticated and flexible architecture for managing and monitoring network traffic.

Finally, we present a table for the system availability as a function of the MTBF (Mean Time Between Failures).<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('77','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_77\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/sol.sbc.org.br\/index.php\/sbrc\/article\/view\/2631\" title=\"https:\/\/sol.sbc.org.br\/index.php\/sbrc\/article\/view\/2631\" target=\"_blank\">https:\/\/sol.sbc.org.br\/index.php\/sbrc\/article\/view\/2631<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('77','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_inproceedings\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Gustavo Herm\u00ednio de Ara\u00fajo, Marcelo Antonio Marotta, Juliano Araujo Wickboldt, Cristiano Bonato Both, Luciano Paschoal Gaspary, Juergen Rochol, Lisandro Zambenedetti Granville<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('78','tp_links')\" style=\"cursor:pointer;\">Caracterizando Estrat\u00e9gias de Dom\u00ednio Espacial para Gerenciamento de Regras em Redes Definidas por Software<\/a> <span class=\"tp_pub_type inproceedings\">Inproceedings<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_booktitle\">35\u00ba Simp\u00f3sio Brasileiro de Redes de Computadores e Sistemas Distribu\u00eddos, SBRC 2017, Bel\u00e9m, Brazil, May 15-19, 2017, <\/span><span class=\"tp_pub_additional_pages\">pp. 788\u2013801, <\/span><span class=\"tp_pub_additional_publisher\">SBC, <\/span><span class=\"tp_pub_additional_year\">2017<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 2177-496X<\/span><span class=\"tp_pub_additional_note\">, (In portuguese)<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_78\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('78','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> <span class=\"tp_resource_link\"><a id=\"tp_links_sh_78\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('78','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_78\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('78','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span> <span class=\"tp_pub_tags_label\">Tags: <\/span><a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=50#tppubs\" title=\"Show all publications which have a relationship to this tag\">Resource Management<\/a> <a rel=\"nofollow\" href=\"https:\/\/www.inf.ufrgs.br\/~jwickboldt\/?page_id=510&amp;tgid=44#tppubs\" title=\"Show all publications which have a relationship to this tag\">Softwarized &amp; Programmable Networks<\/a><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_78\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@inproceedings{conf\/sbrc\/deAraujo17,<br \/>\r\ntitle = {Caracterizando Estrat\u00e9gias de Dom\u00ednio Espacial para Gerenciamento de Regras em Redes Definidas por Software},<br \/>\r\nauthor = {Gustavo Herm\u00ednio de Ara\u00fajo and Marcelo Antonio Marotta and Juliano Araujo Wickboldt and Cristiano Bonato Both and Luciano Paschoal Gaspary and Juergen Rochol and Lisandro Zambenedetti Granville},<br \/>\r\nurl = {https:\/\/sol.sbc.org.br\/index.php\/sbrc\/article\/view\/2673},<br \/>\r\nissn = {2177-496X},<br \/>\r\nyear  = {2017},<br \/>\r\ndate = {2017-01-01},<br \/>\r\nbooktitle = {35\u00ba Simp\u00f3sio Brasileiro de Redes de Computadores e Sistemas Distribu\u00eddos, SBRC 2017, Bel\u00e9m, Brazil, May 15-19, 2017},<br \/>\r\npages = {788--801},<br \/>\r\npublisher = {SBC},<br \/>\r\nabstract = {Software-Defined Networks (SDN) based on Openflow protocol perform data forwarding through flow tables using match\/action mechanisms.
