Implementation of Traffic Engineering Control System for Software Defined Networking

Software Defined Networking (SDN) is an emerging networking paradigm that separates the network control plane from the data forwarding plane with the promise to dramatically improve network resource utilization, simplify network management, reduce operating cost, and promote innovation and evolution. Although traffic engineering techniques have been widely exploited in the past and current data networks, such as ATM networks and IP/ MPLS networks, to optimize the performance of communication networks by dynamically analyzing, predicting, and regulating the behaviour of the transmitted data; the new features of SDN require new traffic engineering techniques that exploit the global network view, status, and flow patterns/characteristics available for better traffic control and management. In this project we develop a new TE management tool called TECS-SENNA, i.e., a traffic engineering control system for SDN/OpenFlow networks in order to provide a dynamically and globally optimized network resource allocation in such a way that the overall performance can be improved, including throughput, latency, stability, and load balancing, while satisfying the per-flow QoS requirements.
