Grafos como uma primitiva do plano de controle para análise e gerenciamento de redes definidas por software

Abstract

Software Defined Networking (SDN) is an emergent architecture that is dynamic, flexible, manageable and with low cost, consistent with the dynamics of modern applications. This architecture decouples the control plane from the data plane. Tipically, networks are represented as graphs. Based on it, this master thesis presents a network representation model using a graph for the control plane of a SDN controller. Our SDN solution adopts the OpenFlow protocol. This project is based on POX, a SDN controller compatible with OpenFlow devices. The graph aproach provides a global view of the network in real time and with consistency. The experiments show that the graph is a reliable representation of the real network and its events occurring over time in the network, thus easing the management in Software Defined Networking.
