Design and Implementation of an Intra-domain routing module for an SDN controller for Traffic Engineering in SDN environment
2015
Software Defined Networking (SDN) provides an environment to test and use custom ideas in networking.One of the areas that needs this flexibility is routing in networking.In this study we design and implement a custom intra-domain routing approach in an SDN environment.In SDN routing can be implemented as part of a controller or as an application on top of a controller.In this study we implemented a module in Floodlight controller v1.1 with OpenFlow 1.3 support.This module interacts with another custom module that monitors active bandwidth use of inter-switch links inside a network.Using the information provided by monitoring module, routing module uses available capacity in inter-switch links to determine widest path between any given two points.We tested and evaluated the developed system to show its efficiency.Newly developed module can be used in traffic engineering with additional control options.
