Paper Abstract

In this paper, we propose a new scheme to realize the robust design for the WDM optical network. Instead of traditional virtual topology based optical network design approaches which depend on the traffic matrix estimation technology, we take advantage of the load balance idea of Valiant to design the network, which can accommodate the dynamic traffic matrix. Considering the specific features of the optical network, we carefully design the full-connected virtual topology to balance the virtual link distribution on the physical topology. In order to achieve this goal, an Integer Linear Programming model is used. Then we decide the capacity for each physical link according to Valiant Load-Balanced principle. At last, the traffic division delivery mode is employed to deliver the traffic on this well designed network. The whole design approach realizes the idea of robustness; it fully utilizes the resources of the network, and can meet the requirements of variable traffic.
