Simulation Analysis of Network Metrics on Virtual Private Network Through Multi-Protocol Label Switching

Multi-Protocol Label Switching is one of the packet-switching technology that uses fixed-length identifier labels to transmit traffic efficiently. The three main services an MPLS supports are Quality of Service (QoS), Traffic Engineering (TE), and Virtual Private Network (VPN). The forwarding mechanism and scalability features of this technology make it more suitable for carrying out real-time application traffic. This paper evaluated the network performance metrics for time-sensitive (video, voice) and Best-effort traffic (FTP, email) in an MPLS-enabled network. The functionality of the MPLS system was performed through the simulation approach using the Riverbed OPNET tool. Analysis of simulated results about network performance metrics shows that there was an improvement in the performance of Time-sensitive in Best-effort traffic on a Virtual Private Network over the MPLS backbone
