Abstract

Multiprotocol Label Switching (MPLS) is a technology that ensures efficient transmission with high speed and lower delays. Traffic Engineering (TE) signal protocols are usually used for active management of  the MPLS networks for efficient utilization of resources. This paper presents performance investigation of  MPLS TE signal protocols  to get a guideline to utilize transmission links efficiently.  Comparison is made between two TE signal protocols, namely Resource Reservation Protocol (RSVP) and Constraint-based Routing Label Distribution Protocol (CR-LDP). Simulation results are presented for three  MPLS networks having different topologies which are implemented in OPNET (version 14.5) environment to support different applications in the absence and presence of quality of service (QoS) algorithms. The results reveal that MPLS network with CR-LDP TE signal protocol has better performance in the term of link utilization. The RSVP reserves certain paths for transmission while the CR-LDP utilizes almost all of the available links.
