摘要：
Risk-disjoint routing is an efficient way to improve network survivability.In this article,a partial risk-disjoint routing algorithm based on link availability (PRDRA-LA) is proposed based on the complete risk-disjoint routing algorithm(CRDRA).While calculating the protection path with PRDRA-LA,the links that share risks with the links in the working path are filtered by link availability.In addition,the risk disjoint degree between the protection path and the working path can be adjusted freely.Simulation results showed that when compared with CRDRA,routing connections with PRDRA-LA can achieve improved survivability while the number of connections that can be successfully routed over the current network is kept from serious decline.
