Research on integrated dynamic multi-layer network survivability based on GMPLS

The coordination mechanism for multi-layer network survivability based on the network architecture of IP/GMPLS over WDM is researched in the paper,(and survivability coordinated scheme based on GMPLS control plane is discussed) key to detailed discussed the survivability coordinated scheme based on GMPLS control plane. Making an analysis and research mainly from several aspects of failure detection,failure notice and coordination control. The whole time of restored failure used can be reduced,and (the survivability of each layer can be effectively controlled) control effectively to the coordination control to the survivability of each layer by the scheme.
