Abstract

The paper proposes a pre-established multi-path model for quantitative QoS guarantees in Differentiated Services (Diffserv) aware MPLS networks. The proposed model pre-establishes several MPLS label switching paths (LSPs) between each ingress-egress router pair. An ingress router performs admission control based on the resource availability on these paths. The model reduces QoS route computation complexity and increases signaling and state scalability. It also increases resource utilization by performing dynamic load-balancing among the paths based on their utilization. The experimental results are provided to illustrate the efficiency of our model under various network conditions.
