| Abstract: | Based on network policy and traffic profile information, a new constrained routing algorithm for MPLS traffic engineering was proposed. The algorithm pre allocates the network bandwidth resources to different traffic classes according to the traffic profile information. Through the combination of explicit route computation and fault recovery mechanisms , a MPLS based fault recovery system was designed and implemented. It was shown that both the utility of network resources and the survivability of MPLS traffic engineering system were enhanced through the treatments. |
