abstract = {The research agenda on programmable data planes has been primarily focused on high-end networking devices, driven by technical requirements derived from operations & management needs of large scale datacenters and cloud providers. In this paper, we argue in favor of a yet incipient but equally paramount and challenging topic in this agenda: research on programmable low-end devices, like Low-power wide-area network (LPWAN). One main motivation is ünlocking" LPWAN, enabling one to freely redefine how they parse and process packets by means of Domain-specific languages such as P4. In addition to reducing capital expenditure by allowing interoperability between devices from multiple vendors, programmability would open LPWAN to an entire novel class of use cases, like providing inclusive internet access to technologically marginalized populations (such as rural communities). To contribute to this emerging research agenda, we propose a conceptual architecture and demonstrate the technical feasibility of a Programmable LPWAN by means of a proof-of-concept prototype, built using off-the-shelf hardware. More importantly, we present and discuss valuable lessons towards the design of such devices, maintaining their popular characteristics (like low power, low cost, long rage) yet freely (re)programmable for a broader class of novel use cases.},

A key challenge is ensuring the rapid spread of vital messages through network-centric Command and Control (C2) systems for situational awareness and effective decision-making in multi-domain operations (MDO). This study explores the enhancement of communication on the BN through the integration of P4 and SDN techniques, from a practical perspective. Modifications to the source code of the Stratum switch operating system enabled priority queues in BMv2, with low queue rates that simulate harsh battlefield conditions. The ONOS CLI was enhanced with simple and intuitive prioritization commands, vital for dynamic and responsive network management. Experiments showed significant reductions in packet loss and delay when using the proposed prioritization approach, highlighting the efficacy of the developed tool.},

abstract = {Software-Defined Networks (SDN) based on Openflow protocol perform data forwarding through flow tables using match/action mechanisms. These tables have limited rules storage capacity, restricting network scalability and performance. Considering these restrictions, the main strategies for managing spatial domain rules, i.e., flow agregation and multiple flow tables, are promising to use the available storage space of the tables. These strategies impact packet processing in different ways, influencing the performance of the forwarding devices and the network. In spite of the impact, the comparison between flow aggregation and multiple flow tables is poorly exploited, leaving open the definition of which strategy is more appropriate for a network considering its topology and workload. In this article a quantitative characterization is proposed, defining the gains brought by these spatial domain strategies for forwarding devices and in different topologies.},

These so-called Smart Grids comprise energy generation, transmission, and distribution subsystems, which are monitored and managed by Supervisory Control and Data Acquisition (SCADA) systems. In this paper, we discuss the benefits of using Software-Defined Networking (SDN) to assist in the deployment of next generation SCADA systems. We also present a specific Network-Based Intrusion Detection System (NIDS) for SDN-based SCADA systems, which uses SDN to capture network information and is responsible for monitoring the communication between power grid components. Our approach relies on SDN to periodically gather statistics from network devices, which are then processed by One-Class Classification (OCC) algorithms. Given that attack traces in SCADA networks are scarce and not publicly disclosed by utility companies, the main advantage of using OCC algorithms is that they do not depend on known attack signatures to detect possible malicious traffic. Our results indicate that OCC algorithms achieve an approximate accuracy of 98% and can be effectively used to detect cyber-attacks targeted against SCADA systems.},

abstract = {Anomaly traffic detection and classification mechanisms need to be flexible and easy to manage in order to detect the ever growing spectrum of anomalies. Detection and classification are difficult tasks because of several reasons, including the need to obtain an accurate and comprehensive view of the network, the ability to detect the occurrence of new attack types, and the need to deal with misclassification. In this paper, we argue that Software-Defined Networking (SDN) form propitious environments for the design and implementation of more robust and extensible anomaly classification schemes. Different than other approaches from the literature, which individually tackle either anomaly detection or classification or mitigation, we present a management framework to perform these tasks jointly. Our proposed framework is called ATLANTIC and it combines the use of information theory to calculate deviations in the entropy of flow tables and a range of machine learning algorithms to classify traffic flows. As a result, ATLANTIC is a flexible framework capable of categorizing traffic anomalies and using the information collected to handle each traffic profile in a specific manner, e.g., blocking malicious flows.},

abstract = {Power grids are responsible for the transmission and distribution of electricity to end-users. These systems are undergoing a modernization process through the use of Information and Communication Technology (ICT), transforming the electric system into Smart Grids. In this context, Supervisory Control and Data Acquisition (SCADA) systems are responsible for the management and monitoring of substations and field devices. In this paper, we investigate the use of SDN as an approach to assist in the modernization of SCADA systems. We discuss its possible benefits, such as simplified management of power system resources. Moreover, SDN can facilitate the creation of new network applications that previously, with traditional networks, were more complex to be implemented. To illustrate the benefits of the use of SDN in SCADA, we designed a mechanism that aims to prevent a possible eavesdropper from fully capturing communication flows between SCADA components. The mechanism was implemented as an SDN-based application for SCADA systems that uses multipath routing, which relies on SDN features to frequently modify communication routes between SCADA devices. Further, we performed an experimental evaluation to verify the impact and performance of the mechanism in the SCADA network.},

abstract = {Software-Defined Networking (SDN) is an emerging paradigm that arguably facilitates network innovation and simplifies network management. However, in the context of SDN, management activities, such as monitoring, visualization, and configuration can be considerably different from traditional networks. An SDN controller, for example, can be customized by network administrators according to their needs. Such customizations might pose an impact on resource consumption and traffic forwarding performance, which is difficult to assess without an SDN-devoted management system. In this paper, we initially present an analysis of control traffic in SDN aiming to better understand the impact of the communication between the controller and forwarding devices. Afterwards, we propose an interactive approach to SDN management through monitoring, visualization, and configuration that includes the administrator in the management loop. To show the feasibility of our approach a prototype has been developed. The results obtained with this prototype show that our approach can help the administrator to better understand the impact of configuring SDN-related parameters on the overall network performance.},

abstract = {Software-Defined Networking (SDN) permits centralizing part of the decision-logic in controller devices. Thus, controllers can have an overall view of the network, assisting network programmers to configure network-wide services. Despite this, the behavior of network devices and their configurations are often written for specific situations directly in the controller. As an alternative, techniques such as Policy-Based Network Management (PBNM) can be used by business-level operators to write Service Level Agreements (SLAs) in a user-friendly interface without the need to change the code implemented in the controllers. In this paper, we introduce a framework for Policy Authoring to (i) facilitate the specification of business-level goals and (ii) automate the translation of these goals into the configuration of system-level components in an SDN. We use information from the network infrastructure obtained through SDN features and logic reasoning for analyzing policy objectives. As a result, experiments demonstrate that the framework performs well even when increasing the number of expressions in an SLA or increasing the size of the repository.},

[3] proposed FlowSense, which is aimed to keep the lowest control channel overhead and the highest information accuracy as possible in OpenFlow monitoring. Chowdhury et al. addressed SDN monitoring from a different perspective. The authors proposed Payless [4] framework that is able to deal with monitoring considering the polling frequency and data granularity. Payless relies on OpenTM [5] to select only important switches to be monitored, also aiming to reduce the overhead imposed in the control channel. Thus, this framework allows to adjust the polling frequency parameter to balance the control channel overhead, imposed by monitoring messages, and accuracy of monitored information.},

abstract = {Software-Defined Networking (SDN) provides a sophisticated and accurate solution for managing network traffic. SDN logically centralizes, in devices called controllers, part of the decision-making logic of flow processing and packet routing. The whole network is controlled according to rules written and deployed in the controller device. However, the large amount of network devices, links, and services also gives rise to a large number of rules to be managed in the controller. Policy-Based Network Management (PBNM) can be used to manage complex network infrastructures through policies rather than specifying device-by-device configurations. Particularly, policy refinement techniques can be used to automatically translate high-level policies into a set of low-level ones. In this paper, we define a formal representation of high-level SLA policies using Event Calculus (EC) and apply logical reasoning to model both the system behavior and the policy refinement process for SDN management. We also describe the implementation of this formal model in Prolog, which enables the automatic inference of low-level policies from high-level ones, and present evaluation results.},

abstract = {Software-Defined Networking (SDN) is a dynamic, adaptable, controllable and flexible network architecture. It provides an extensible platform for delivery of network services, capable of responding quickly to service requirement changes. As a result, SDN has become a suitable scenario for the application of techniques and approaches for improved infrastructure management, such as Policy-Based Management (PBM). In PBM, using techniques such as refinement, a high-level policy-e.g., specified as a Service Level Agreement (SLA) - can be translated into a set of corresponding low-level rules, enforceable in various elements of a system. However, when using SLAs, their translation to low-level policies, e.g., for controller configuration, is not straightforward. If this translation is not done properly, the controller may not be able to meet the implicit requirements of the SLA, failing to satisfy the goals described in the high-level policy. This paper proposes a novel approach towards SLA policy refinement for Quality of Service (QoS) management (based on routing) in Software-Defined Networking. It consists of an initial manual process performed by an administrator, followed by an automatic policy refinement process executed by an OpenFlow controller. As a result, our approach is capable of identifying the requirements and resources that need to be configured in accordance with SLA refinement, and can successfully configure and execute reactive dynamic actions for supporting dynamic infrastructure reconfiguration.},

abstract = {Infrastructure as a Service (IaaS) clouds are becoming a customary way to deploy modern Internet applications. Many cloud management platforms are available for one who wants to build a private or public IaaS cloud (e.g., OpenStack, Eucalyptus, OpenNebula). A common design aspect of current platforms regards their black-box-like controlling nature, where cloud administrators have few opportunities to influence how resources are actually managed (e.g., virtual machine placement or virtual link path selection). We envision that administrators could benefit from customizations in resource management strategies to achieve environment specific objectives or to enable application oriented resource allocation. Therefore, we present Aurora Cloud Manager platform, which introduces a new level of flexibility in resource management by the addition of programmability to the core of the platform, with a simplified object-oriented API. The platform is mostly developed in Python and brings together several third party tools, libraries, and systems in order to materialize the proposed concepts. Lower level libraries, such as Libvirt, OpenFlow, and Open vSwitch, provide abstractions for node virtualization and networking operations. The Aurora platform also ships with a set of high-level and customizable resource allocation algorithms for both deployment and optimization of cloud applications.},

abstract = {The disheartening and thorny path followed while deploying new solutions in the core of current computer networks, culminates in a low rate of emergence of innovation. Several researches proposed applying Software Defined Networks (SDN) and the Network Virtualization (NV) concepts to reverse this rate. However, many gaps and open challenges were observed in the application of these concepts together. In this paper, we propose the ProViNet platform, which merge the SDN and NV concepts to provide a fast and safe deployment of innovations in the existing network infrastructure. ProViNet advance the state-of-art introducing the concept of Network Programming as a Service, in which applications are built simply by composing control plane services. Such approach encourages End-Users to develop and share novel network solutions, fostering innovation. To prove concept and technical feasibility, we evaluate ProViNet with a prototype that allowed demonstrating virtual network infrastructure provisioning and programming.},

abstract = {Most of the current platforms for cloud infrastructure management are designed to deal mainly with computing and storage resources. However, when deploying highly distributed applications with strict network requirements, such as low delay or bandwidth guarantees, the support for specification and configuration of such requirements still lacks. Moreover, resource allocation strategies and algorithms are usually hard-coded into the cloud platform's core, making it very difficult to improve or adapt these strategies to better lit individual application and environment needs. In this paper, we introduce a new approach to cloud platform design, emphasizing three main aspects: (i) robust networking for coupling cloud computing with modern network paradigms, (ii) specification of complex virtual infrastructures, including network topology and application requirements, and (iii) programmability via an API to ensure customization at the core of the platform's resource allocation and optimization strategies. We still present a proof of concept prototype that we have implemented and deployed over a modern network testbed and also evaluated on an emulated network using Linux virtualization containers, Open vSwitch, and mininet. Using our prototype, we have conducted a case study featuring an information-centric networking (ICN) application. Initial results show the feasibility of our approach and the application deployment statistics.},

abstract = {Current cloud management platforms have been designed to deal mainly with computing and storage resources. Networking, on the other hand, is often focused only on ensuring basic connectivity between virtual machines. That means, advanced requirements, such as delay and bandwidth guarantees or handing of network control to the customer, are not supported in today's platforms. Another important shortcoming is that resource management strategies are mostly implemented as part of the core of platforms, leaving little or no room for personalization by the operator or the customer. Therefore, in this paper we present the building blocks of a new conceptual architecture of a cloud platform aiming to add advanced yet robust network configuration support and more flexibility at the core of the platform to better fit the needs of each cloud environment.},

abstract = {The purpose of our prototype is to demonstrate that our concept of cloud platform, is suitable for the deployment of complex and mainly network intensive applications. Therefore, in this demo we intend to show the deployment of a NetInf application. NetInf is a novel information-centric networking platform being developed also under the SAIL project. It basically encompasses routing information through a network based on the content itself instead of relying on regular network addressing schemes. One of NetInf’s assumptions is that in the future network devices will be shipped with native support to NetInf protocol. This is assumption obviously not yet satisfied by current networks, so NetInf applications will rely on cloud platforms that can meet their unusual communication needs for large scale deployment.},
