Comparison between Different Topologies of IP Networks Using MPLS

Abstract

In the present work, a comparison between two virtual IP networks with different topologies using the MPLS technology is made. The difference in topologies is the presence of an MPLS core network. In one topology, there is no clearly defined MPLS core network, and in the other, there is. The aim of the work is to make a comparison between the two virtual IP networks and to check which of the two topologies will have an improvement in the performance of the virtual IP network. For the purposes of the study, only VoIP traffic is exchanged in virtual networks and various tools for monitoring of IP networks are used.
