Abstract: This paper firstly studies the RWA algorithm in WDM optical network, then proposes a novel self-adaptive RWA algorithm considering lightpath PRI and network fairness and gives the detailed approaches. The algorithm can make full use of network resources and keep the load distribution in balance, and also give attention to the rationality of network resource assignment.
