A Capacity Allocation Algorithm for Optical Virtual Private Networks

Bin ZENG, Rui WANG

Abstract


As the development of optical communication technologies such as Wavelength-Division Multiplexing (WDM), it is important to support virtual private networks (VPN) over WDM networks. In order to overcome the limits of WDM network capacity and achieving more revenue new VPNs, an optimal model supporting both optical VPN and IP VPN on WDM networks is proposed to admit the maximum number of new VPNs without influencing the QoS guarantee for the existing VPNs. Furthermore, three heuristic algorithms are designed to simplify the computation process of getting optimal solution. The simulation results over MESH WDM networks show the algorithm can takes advantage of the reliable transmission capability of WDM networks and provides diverse QoS for different traffic streams by different quality of optical transmission.
