Abstract
GMPLS-based multi-layer networks (MLN) combining packet and optical switching lead to jointly leverage intrinsic per-layer benefits such as statistical multiplexing and huge transport capacity. By doing so, efficient network resource utilization is attained through MLN TE strategies, i.e. grooming. In this context, an optical link failure may cause the disruption of multiple groomed packet LSPs. Thereby, efficient recovery schemes such as restoration are required. In dynamic restoration, the cen...
