Abstract:
Routing is the function of seeking a path between all possible in a packet network topologies which have great connectivity. Because it comes to find the best possible route, the first step is to define what constitutes best route and consequently what is the metric to measure it. This parameter and the operation of the routing protocol itself give us the protocol performance. This work presents a comparative study of three of the most used routing protocols, i.e., Routing Information Protocol (RIP), Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP) in ring topologies. Through this study, the performance of each routing protocol is analyzed. To this purpose, we have used a network simulator known as GNS3 that allows simulating different network scenarios using real operating systems (IOS) of CISCO equipment. We have simulated a topology with these three protocols in order to observe and analyze the network behaviour, traffic flow, time of routes updating and network convergence. As results show, RIP presents the lowest time for initializing the network while OSPF is the protocol that presents highest time in initializing process of network. Finally, EIGRP shows the best convergence time after the first fault in the network.
