Survey for Traffic Engineering in Software Define Networks

As a result of the development in applications of communication networks with emergence of software define networks (SDN) decouples the control plane and data plane of the networks. therefore, the traffic engineering (TE) mechanisms is one of the most important technologies to be within the application layer which optimizing traffic, improve network robustness, and avoid network congestion. This papers reviews the TE methods for SDNs that exploited data networks depend on several criterial with respect to continuous update of network configuration in term of achievable network throughput.
