The Design of Routing Framework for Protection & Restoration of Multi-Layer Based on GMPLS Network

The IP layer of obstacles, such as routers optical-transmission malfunction in the hierarchy can not handle. These types of obstacles that need and packet-level rerouting, if packet-level rerouting long time backup LSP or tunneling path through the ability to automatically switchover needs. Disability for a certain amount of resilience backup (protection), or to require extra capacity. There is no unified control, such as GMPLS flat-recovery scheme, and the other is performed independently of any information about the hierarchy´s behavior can never know.The credibility and survival of the research is to build networks that can provide for GMPLS network, multilayer protection and recovery capabilities to provide a signal / routing framework and objectives of this paper.
