Performance Analysis of Edge Nodes with Multiple Path Routing

Multiprotocol label switching (MPLS) can flexibly establish one or several paths for traffic demands in the form of label switched paths (LSP). In this paper we propose a scheme for the multiple LSPs operation of edge nodes in MPLS networks. The proposal comprises the mechanisms of load-dependent path-decision, intervention and path selection policy to facilitate efficient LSP routing. We develop a performance model to evaluate the performance of the proposed scheme.
