摘要：
Restoration is a very critical issue in WDM optical networks. Provisioning also plays a great role in the networks because it deals with resource allocation. In this paper, we have presented two provisioning strategies for restorable networks: unity link weight strategy and varying link weight strategy. The strategies are implemented for critical applications which require 100% degree of survivability. The simulation is done using different proportionate of resources for working and restoration lightpaths. The simulated results show that the performance of the unity link weight strategy is much better than the varying link weight strategy in terms of resource requirement and blocking probability.
