A Comparative Analysis of OSPF and EIGRP Routing Protocol Evaluation

Abstract

In recent decades, technology has advanced quickly in every area of human life, but network data communications have grown at a particularly rapid rate. New terms like "Internet of Things," "Cloud" services, or "Bring your own devices (BYOD)" have been used to describe new ways of working, communicating, and socializing. The evolution of routing protocols has taken a similar course; simple distance vector protocols gave rise to the development of link state and hybrid protocols. Business demands for managing public and private cloud services, as well as the quick convergence of data centres to meet redundancy needs, have led to this progression. In order to accomplish their objective, routing protocols choose the best routes for transferring data from one node to another and define how routers communicate with one another. Exterior Gateway Protocol (EGP) and Interior Gateway Protocol (IGR) are the two primary kinds of routing protocols. The goal of this article is to evaluate the behaviour of OSPF and EIGRP, two IGR protocols that now control the market for industry standards in this area. Both function inside an autonomous system, and despite differences in how they build associations between attributes, how they respond to changes, and how they organize themselves topologically, they both succeed in delivering the same outcome in strong routing and network stability. Network convergence and communications timing, as well as packet delay variations regarding two distinct typologies, are evaluated as performance aspects in this paper. The first typology offers a basic framework for comparison, while the second looks at how scale affects both protocols.
