Paper Abstract

Failures in the GMPLS (Generalized Multi-Protocol Label Switching) control plane and in the data plane may independently occur. The established data plane connections such as lightpaths in WDM networks must remain operational in the event of a control plane failure. A control plane failure should not cause changes of the state of connections and resources in the data plane. In addition, the control plane needs to recover the lost state information, or acquire up-to-date state information. The engineering of GMPLS control plane failure recovery techniques must consider different failure scenarios, co-ordinations of different recovery mechanisms. In this paper, we summarize the graceful restart mechanism for the signalling protocols, then present a two-step failure recovery of the signalling protocols to improve the recover speed.
