Influence of Signaling Protocols in MPLS-TE Performance

S. Veni, Dr.G.M. Kadhar Nawaz, P. Praba

Abstract


Multiprotocol Label Switching (MPLS) is an Internet Engineering Task Force (IETF)-specified framework that provides for the 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-speed, scalability, quality-of-service (QoS) management, and traffic engineering. Constraint-based Routing Label Distribution Protocol (CR-LDP) and  Resource Reservation Protocol  - Traffic Extension(RSVP-TE) are two label distribution protocols that provide support for Traffic Engineering. The operation of two protocols is different although the two protocols provide a similar level of service. The choice of signaling protocol is crucial for the success of MPLS performance.
