Implementing shortest path routing mechanism using Openflow POX controller

Network management is a challenging problem of wide impact with many enterprises suffering significant financial losses. The Software Defined Networks (SDN) approach is a new paradigm that enables the management of networks with low cost and complexity. The goal of SDN is to make sure that all control-level logical decisions are taken at a central way, as compared to traditional networking, wherein control-level decisions are taken locally and intelligence is distributed in each switch. The aim of this paper is to present a routing solution based on SDN architecture implemented in OpenFlow environment and providing the shortest path routing. The simulations have been carried out in an emulation environment based on Linux and POX controller.
