Service-Oriented Cross-Layer Survivability Strategy

A serviced-oriented cross-layer survivability strategy is proposed based on GMPLS control plane (SCSG). The strategy provides the differentiated services are implemented by using regeneration node configuration scheme based on quality of transmission (QoT). The network survivability is guaranteed by using segment protection scheme based on regeneration node. The duplication of resource assignment and conflict of interlayer survivability strategy are avoided by using cross-layer route mapping based on GMPLS control plane. The results show that the proposed survivability strategy not only can provide differentiated services, but also can improve network survivability and resource utilization.
