In the ASON architecture, optical network is viewed as a separately deployed transport network providing transparent transport service to IP/MPLS domain networks. As ASON lack of scalability and efficient traffic grooming, GMPLS enabled multilayer network is a promising alternative for deployment of IP over WDM network. The multilayer network composed of network node that is based on the hybrid architecture integrating IP/MPLS layer and optical switch with a unified GMPLS control instance can bypass lightpath at optical layer or terminate a lightpath locally at IP/MPLS layer. This paper illustrated the architecture of G-LSR, and addressed the essential aspects of network operation mechanisms including multilayer routing, lightpath provisioning and LSP hierarchy provisioning. Current IP network can gradually evolve to IP/optical integrated multi-layer network through updating network node of IP router to G-LSR.
