This paper proposes a new provisioning scheme of the WDM networks to guarantee the recovery time defined in service level agreement (SLA). In our proposed scheme, the fault management scheme and working path or a pair of paths are selected based on the comparison of the pre-calculated recovery time with the recovery time required by the customer in resource efficient manner. Simulation results show...
In this paper, a simple and fast restoration method independent of failure location in all-optical networks is proposed. The proposed method uses a single fixed restoration wavelength for any link failure and employs edge-disjoint path restoration (DPR). The restoration process is triggered just after failure detection without the need to identify failure location and accelerated by a parallel crossconnection...
