Improvement of performance of EIGRP network by using a supervisory controller with smart congestion avoidance algorithm

Abstract

The aim of this research is to enhance the performance of a traditional Enhanced Interior Gateway Routing Protocol (EIGRP) network by adding some features of the Software Defined Networking (SDN) in a modified approach to improve some network's performance metrics like link congestion and packet loss. The improvement of those metrics leads to an improvement in the total throughput of the network. This approach results in a network that contains an intelligent dynamic supervisory corrector controller, which is capable of detecting the location of a congestion that may take place before or at the brink of its occurrence and dealing with selected flows on selected routers across the network in a way that prevents the congestion by using a smart heuristic congestion avoidance and routing algorithm thereby reducing the generation of control messages as much as possible.
