Implementing Carrier Services in OpenFlow- OpenFlow Switch as MPLS PE-Router The aim of this project is to build an OpenFlow underlay network and deploy value-added carrier services like L2VPNs, L3VPNs. As many projects in this area rely on the functional level only and implement the functionality in a virtual environment this research also includes testing the setup with real hardware in the form of a physical OpenFlow switch and physical routers that build the MPLS core network. Performance comparisons and scalability envelopes of such deployments with traditional IP/MPLS-based networks will also be presented. Software Defined Networking (SDN) using OpenFlow allows the control of traffic in an SDN controlled network based on header fields of the packets or even the content if packets are sent to the SDN controller for analysis. In an ideal world networks can be built from scratch and in such an environment SDN technology can be used to control all of the networks. However, in real life existing infrastructures and SDN networks need to co-exist and interwork.
