Abstract :
A restoration scheme has been designed for multi-domain optical network, which solve the problem of resource conflict during fast rerouting. This scheme propose the concept of dual-weight recovery(DWR) for the first time. The DWR which use the path computation element (PCE), can optimize resource distribution in multi-domain network and provide priority of using resource for recovery. At the end of this paper, simulation result shows that DWR scheme has good performance in blocking probability.
