Network Performance Analysis of Interior Gateway Routing Protocols using GNS3

Communication technology facilitates provision of such services as file transferring, print sharing, video streaming and voice conferencing. Internet is a worldwide system of interconnected computer networks. Today Internet is playing a vital role in communication networks. Computer communication networks are based on a technology that 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 disseminating information. Every protocol has its own feature of packet routing. The router has prior knowledge about the adjacent networks, which can assist in selecting the routes between two nodes. This paper presents a simple comparative performance analysis of interior gateway routing protocols with specific criteria convergence time, end to end delay, bandwidth, hop count, administrative distance, round trip time, memory allocation and so forth.
