The world is experiencing rapid and tremendous growth in computer communication network technology. This technology provides the technical infrastructure, where routing protocols are used to transmit packets across the Internet. Routing protocols specify how routers communicate with each other by spreading information. Enhanced Interior Gateway Routing Protocol (EIGRP) is one of the hybrid protocols, which is based on Interior Gateway Routing Protocol (IGRP). In our work titled “Improved Shortest Path First Algorithm for Enhanced Interior Gateway Routing Protocol (EIGRP)”, we proposed an improved shortest path first algorithm (ISPFA) used in enhanced interior gateway routing protocol. This work addressed the end-to-end delay problem associated with the existing routing protocol. In this paper, we carried our comprehensive analysis of the proposed protocol and assessed its comparative performance with existing protocol. The analysis shows average improvement of 36% by the proposed protocol over the existing.
