Uma solução de Engenharia de tráfego para redes com múltiplas conexões WAN, baseada em SDN

Abstract

The Traffic Engineering aims to optimize network performance. To achieve better performance, it uses techniques that seek the reduction of congestion on the network, improving their performance. Traffic engineering techniques have been widely used in current and legacy networks. However, new network requirements have emerged, requiring the emergence of new network paradigms and creating new traffic engineering technologies. In this context, a new network paradigm known as Software Defined Network (SDN). SDN is a networking paradigm that has the purpose of separating the control plane from the data plane. It makes the network programmable, transferring the routing decision to external devices. This paper proposes an SDN solution of traffic engineering for networks with multiple external connections, allowing the direction of traffic through the network and policy-making at a high level. A case study was performed to validate our solution.
