Link Recovery Comparison Between OSPF & EIGRP

This research is a performance comparison of router protocol between OSPF and EIGRP when an internet link fails. Since OSPF and EIGRP protocols are mostly used nowadays, it is interesting to do experiment with these two protocols. The experiment is setup to find out the retransmission time and rerouting time from both protocols when there is a failure link in a data transmission path. Before there is a failure link, the average transmission times are 18.7ms with OSPF and 18.4 with EIGRP. Then the average transmission times increase to 28ms and 27.5ms for OSPF and EIGRP respectively after a link fails. Additionally, the rerouting time is 5s using EIGRP shorter than 8.8s using OSPF. Finally, the research experiment results show that EIGRP is a better than OSPF in both retransmission time and rerouting time after a link fails.
