| Abstract: | Survivability is a key networking problem of optical network. With the development of the telecommunication network, the research about survivability is more urgent than ever before under the current condition of network. Especially for the multi-layer network survivability, it is significant for the current network structure. To solve the inconsistent inter-working in the multi-layer network failure recovery, an IP/GMPLS/Optical network structure has been presented. Based on this network structure an integrated survivability scheme of multi-layer network has been proposed with GMPLS control mechanism. An optimized performance has been acquired based on this survivability strategy. |
