Internet Protocol Version 6 over Multiprotocol Label Switching

This paper presents a study of performance of voice and FTP traffic based on simulative and analytical methods in IPv4/IPv6 over Multiprotocol Label Switching (MPLS) networks. The research aims to find out what Internet protocol performs better in MPLS networks. Will analyze a series of IPv6 and IPv4 over the MPLS backbone using a simulation tool (OPNET) and will evaluate and compare their performances. The analysis will include comparing the traffic sent and traffic receives, FTP upload response time, FTP download response time and voice delay variations. The simulation is set up and configured to obtain results based on OPNET simulator. The experiment includes two scenarios the first scenario is IPv4 over MPLS and the second scenario is IPv6 over MPLS.
