Performance Evaluation of OSPF-Based Data Network

The implementation of the Open Shortest Path First (OSPF) Routing Protocol for data network has became imperative as the size of the internet growing at an alarming rate and data network needs to employ Routing Protocol to route data faster so as to prevent network congestion and high IP drop across a data network. The Open-Shortest Path First (OSPF) protocol, due to its use of route cost as its metric provides better scalability than rival protocols and a reasonable convergence time. We investigate the performance of OSPF routing protocol in a WLAN. This is done with the help of OPNET IT GURU 9.1, in which six scenarios were simulated for the throughput, delay and IP Traffic dropped for both OSPF and RIP. The result showed that network performance was enhanced by a 50-150% range when the OSPF routing protocol was used instead of Routing Information Protocol (RIP).
