Implementing TrafficEngineering with Segment Routing using OpenDaylight Controller and Pathman-SR

Today, Internet service providers and enterprise networks are facing rapid changes and growing rapidly, and network operations become complex to support these demanding applications. In traditional IP/MPLS networks, the operation becomes complex because of complicated traffic engineering configurations. Service providers and enterprises are demanding more scalable, flexible, and programmable solutions to keep up with the rapidly changing demand to support demanding applications. Segment Routing (SR) is a source routing technology which helps overcome the traditional IP/MPLS networks' drawbacks in scalability, flexibility, and applicability in Software-Defined Networking (SDN). This paper will present how we can implement SR-TE tunnels from Pathman-SR [9] running on top of the OpenDaylight SDN controller. We will also present how we can see the whole view of network topology that Pathman-SR can provide and program SR-TE tunnel from the SDN controller.
