Performance analysis and the study of the behavior of MPLS protocols

MultiProtocol label switching (MPLS) is the new means to take care of the fastest growing communication network to enhance the speed, scalability and service provisioning capabilities. In order to optimize the use of transmission resources, 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. The core value of MPLS is followed by the comparison of MPLS network with the existing network and MPLS signaling protocols: constrained based label distribution protocol (CR-LDP), resource reservation protocol (RSVP) and traffic extension RSVP (RSVP-TE) maintaining the quality of service (QoS) parameters and their performance analysis as well. In such context, 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 and the functionalities of MPLS signaling protocols as well. Finally, the results are evaluated and analyzed, and their behaviors are shown by means of graphical manner.
