Abstract
It is believed that on-demand dynamic lightpath provisioning will enable service providers to respond quickly and economically to customer demands. One of the challenges involved in designing wavelength-routed networks with dynamic traffic demands is to develop efficient algorithms and protocols for establishing lightpaths. This paper proposes a novel dynamic path-selection algorithm that combines service path link using probability weight with efficient disjoint-path restoration bandwidth sharing to obtain a balanceable traffic distribution during the wavelength route selection, and consider the wavelength bandwidth capability sharing between the disjoint paths for the failure scenario. At the same time, to realize dynamic lightpath establishment, this paper discusses the strategy of lightpath establishment based on Automatically Switched Optical Network (ASON), and also presents the extension of GMIPLS protocols to efficiently collect and distribute the necessary information in ASON architecture frame. Through the distributed IP-centric protocol we can realize link state update and dissemination. To sum up, in this paper we hope to show a full and efficient dynamic path establishment mechanism with ASON control plane function and GMPLS principle.
