Beaver View: uma ferramenta interativa para o gerenciamento de infraestrutura virtual Docker baseada em SDN

Abstract

The flexibility and programmability provided by the Software Defined Networks (SDN) paradigm have enabled new services and applications to control and manage digital communications infrastructures, giving new opportunities for building robust and extensible scenarios. Despite the benefits offered by the SDN approach, infrastructure management remains a challenge due to different mechanisms integrated with it. In a virtualized infrastructure such as Docker, the SDN controller does not act directly with the bridges of Docker, making it difficult to apply QoS policies. This work aims to provide a tool for the network administrator that will alleviate his task of dealing with the complexities of SDN infrastructure. We opted for a Hybrid SDN approach to enable QoS control and Firewall policies. To validate the proposed tool, we performed two experiments, where the goal was to block and allow network traffic through the firewall feature and limit the transmission rate of a container using the TBF row discipline. The results show that the proposed solution met the objectives and is a viable option for developers, network administrators, and researchers.
