Performance Analysis and the Study of the Behavior of MPLS Protocols
Multi Protocol Label Switching (MPLS) is useful in managing communication networks. It increases the scalability, speed and service provisioning capabilities of the network. MPLS carries out different tasks using a virtual path technology and this optimizes the use of transmission resources. This paper studies the behavior and performance of multi protocol label switching. MPLS works with a router, which placed on the edge of the MPLS domain. This router is called Label Edge Router or LER. Under the MPLS network, internal router performs swapping. The paper also discusses the signaling protocols used in MPLS networks. There are three main protocols used in the networks, namely, Label Distribution Protocol (LDP), Constraint based Routing LDP (CR-LDP) and Resource Reservation Protocol-Traffic Engineering (RSVP-TE). This paper specially pursues the comparative study of traditional and MPLS network. It starts with the study of Traffic Management. Next part of the paper studies simulation arrangements. These arrangements use parameters such as traffic patter, topology and numerical results. The default specification used for studying traffic management is of G.711 codec. Under this codec, user datagram protocol and bidirectional constant bit rate are used as VoIP services. However, for every increase in voice payload per packet, the net bandwidth is reduced. The paper finally draws its conclusion for MPLS.
