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 = {Currently, many investigations addressed SDN management considering using monitoring information for different purposes. Zhang [1] used monitoring information to develop algorithms for anomaly detection and traffic engineering. Jose et al. [2] used the same monitoring information to propose mechanisms for online measurement of large traffic aggregates. Yu et al. [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 é um paradigma de redes que permite facilmente projetar, desenvolver e implantar inovações de rede, pois fornece agilidade e flexibilidade na incorporação de novos serviços e tecnologias. As redes baseadas nesse paradigma ganharam destaque a partir da especificação do protocolo OpenFlow, que define uma simples interface de programação para controlar dispositivos de encaminhamento a partir de um controlador. Apesar da rápida disseminação desse protocolo, os trabalhos relacionados sobre OpenFlow não analisam em profundidade os reais impactos das mensagens de controle e monitoramento gerado por esse protocolo. Desta forma, a principal contribuição deste artigo é uma análise quantitativa do tráfego de controle e 

monitoramento em redes OpenFlow. Os resultados revelam que variações do tempo limite de ociosidade das regras de encaminhamento, da frequência de monitoramento e da topologia da rede, impactam na taxa de transferência e na quantidade de mensagens geradas no canal de controle.},
