In this paper, the authors provide the detailed investigation of three well-known routing protocols namely IS-IS, IGRP and RIP for fifty workstations which have increasing number of packets from 100 to 1000 in steps working on three dissimilar applications i.e. ftp, remote login and videoconferencing respectively. Simulation is carried out with the help of Optimized Network Engineering Tool (OPNET) which gives the better edge over the other network simulation tools available. Videoconferencing Packet Delay Variation (PDV) and packet end to end delay are the parameters used to measure the routing performance of the network and the results illustrated that IGRP performs well for PDV which gives minimum variation where IS-IS attains good results for videoconferencing packet end-to-end delay for increasing number of packets.
