Performance analysis of network traffic behavior in conventional network over MPLS

Multiprotocol Label Switching (MPLS) is an Internet Engineering Task Force (IETF) specified framework that provides for the efficient designation, routing, forwarding and switching of traffic flows through the network. MPLS is a versatile solution to address the problems faced by present-day networks like speed, scalability, quality-of-service (QoS) management, and traffic engineering. MPLS carries differentiated services across the Internet through a virtual path capability between packet (label) switches. MPLS also has the capabilities to engineer traffic tunnels by avoiding congestion and utilizing all available bandwidth with an efficient manner. MPLS signaling protocols are Constrained based Label Distribution Protocol (CRLDP), Resource Reservation Protocol (RSVP) and Traffic Extension RSVP (RSVP-TE). In this paper, a full comprehensive simulation environment is created for a conventional network and MPLS applied over that traditional network to evaluate the comparative performance of network traffic behavior. Finally, the results are evaluated and analyzed, and their behaviors are shown by means of graphical manner.
