A resilient OBS/GMPLS network for survival optical grids

Survivability is a key issue in optical grids. In this paper, a resilient Optical Burst Switching (OBS) / Generalized Multi-Protocol Label Switching (GMPLS) network scenario, in which both the protection/restoration in the OBS layer and GMPLS layer and the resilient resource discovery and management scheme are experimentally demonstrated and theoretically analyzed. The results show that the proposed solutions are feasible and efficient.
