A Proportional Performance Investigation Route Relocation Amongthree Different Routing Protocols Using Opnet Simulation

Abstract

In today's real-world scenario, using multiple dynamic routing protocols for forwarding packets has become a normal job for the network administrators. Therefore, the route redistribution is an important issue in an enterprise network that has been configured by multiple different routing protocols in its routers. In this study, we analyze the performance of the combination of three routing protocols in each scenario and make a comparison among our scenarios. We have used the OPNET 17.5 simulator to create the two scenarios in this paper by selecting three different routing protocols from the distance vector and link state routing protocols in each scenario. In the first scenario, we have configured the network routers with EIGRP, IGRP, and OSPF that is named EIGRP_IGRP_OSPF in our simulation. Here EIGRP is used on the server side and OSPF is used on the client side. The OSPF_IGRP_ISIS scenario is a mixed from EIGRP, IGRP, and IS-IS protocols that is the second scenario and OSPF is used on the server side and ISIS is used on the client side. The third scenario is OSPF_IGRP_EIGRP that is the route redistribution among OSPF, IGRP, and IS-IS protocols and OSPF is used on the server side and EIGRP is used on the client side. The simulation results showed that the performance of the EIGRP_IGRP_ISIS scenario is better than the other scenarios in terms of network convergence time, throughput, video packet delay variation, and FTP download response time. In contrast, the OSPF_IGRP_ISIS has less voice packet delay variation, video conferencing and voice packet end-to-end delays, and queuing delay as compared with the two other scenarios. On the other hand, the performance of the OSPF_IGRP_EIGRP scenario has the better FTP upload response time, and voice jitter.
