Abstract

A PCE-based congestion avoidance (CA) and Virtual Network Topologies (VNT) reconfiguration (CA-VNTR) routing scheme is proposed and detailed algorithm of CA-VNTR is provided. Simulations are conducted to compare the proposed scheme with traditional routing method in terms of blocking probability and resource utility. Results show that CA-VNTR outperforms traditional routing method in blocking probability, especially under heavy traffic load.
