Performance Evaluation of MPLS Path Restoration Schemes using OMNET++
Multi-Protocol Label Switching (MPLS) is an alternative to integrate Internet Protocol (IP) routing and switching technologies because it provides end-to-end Quality of Service (QoS), guarantees traffic engineering, and support Virtual Private Networks (VPNs). However, MPLS must use path restoration schemes to guarantee the delivery of packets through a network. Considering that MPLS is a label switching technology, it uses a method for label distribution based on signaling protocols like LDP (Label Distribution Protocol) among others. In this paper we present the simulation of some LDP messages and assess the performance of three path restoration schemes (Haskin, Makam, and Simple Dynamic) in an MPLS network using OMNET++. The simulation results show that the Simple Dynamic scheme presents a reduced arrival time when sending a message from the source to a destination, when compared to those times obtained to Haskin and Makam schemes.
