Performance Analysis of Routing Protocols for Real Time Application

Abstract: Routing protocols are used to determine the shortest path to the destination. Information on network is delivered using dominant interior routing protocols like RIP, OSPF, EIGRP and IGRP but knowledge for selection of right protocol is must to experience better performance on network services like VOIP, Video Conferencing, HTTP and FTP. In this paper, Comparison among Interior Gateway Protocols (IGP) protocols is done with weighted-faired queuing (WFQ) technique on different scenarios using OPNET (Optimized Network Engineering Tool) as a simulation tool which provides guidelines to network engineers to decide which protocol should be deployed for a custom specific application as per individual’s choices. Results show that EIGRP will be the best choice for FTP, Email and DB access as compared to other protocols for non real time applications whereas OSPF and IGRP gives better performance in case of real time application.
