Abstract

Abstract

One of the key issues in integrated dynamic IP and wavelength routing algorithm is how to determine whether it is better to route an arriving Label Switch Path (LSP) estab-lishment request over the existing topology or to open new wavelength paths, A new scheme, Bandwidth Defragment Method (BDM), is presented in this paper. It makes full use of the statistic information of the networking link-state and resource availability to determine how to route an arriving LSP request. The integrated dynamic Routing and Wavelength Assign-ment (RWA) algorithm based on BDM can reduce the numbers of bandwidth fragment and increase the utility of network resource. Simulation results show that the scheme can improve the performance of the network significantly.
