Design and Implementation of an Intra-Domain Routing Module for an SDN Controller for Traffic Engineering in SDN Environment
Software Defined Networking (SDN) provides an environment to test and use custom ideas in networking. One of the areas that need this flexibility is routing in networking. In this paper, they 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 paper, they implemented a module in floodlight controller v1.1 with open flow 1.3 supports. 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.
