Modeling of the convergence time of an IP - based network with different traffic loads

In the present work a modeling of an IP - based corporate network with different traffic loads - Internet browsing, video conferencing, working with databases and VoIP calls has been done. The purpose of the modeling is to check the convergence time of the modeled network for different traffic loads using different routing protocols. Modeling is done for the following protocols: RIP, EIGRP, OSPF, OSPFv3 and RIPng. Additionally, modeling was done when part of the links between the branches in the network fails and after some time recovers. This is done to determine what would be the convergence time when the network topology changes during operation.
