Abstract :
Voice over internet protocols (VoIP)´s quality communication relies significantly on the network; however guarantee the best quality of the traffic is difficult. This paper analyzes the performance of VoIP traffic in Border Gateway Protocol (BGP) -Multiprotocol Label Switching (MPLS) IP Virtual Private Network (VPN) between two interior routing protocols namely Enhanced Interior Gateway Protocol (EIGRP) and Open Shortest Path First (OSPF). The combination of MPLS and conventional routing improve the forwarding mechanism, scalability and overall network performance. OPNET Modeler 14.5 is used to simulate both scenarios and metrics such as delay, jitter and mean opinion score (MOS) value are measured. The simulation result shows OSPF and BGP-MPLS VPN provides better infrastructure for VoIP VPN application.
