Variety of security issues exist while all-optical networks provide high-speed transmission,therefore effective means and strategies are needed to repair failure.This paper puts forward a multi-objective routing and wavelength assignment method based on SDN.The method is based on service function chain of SDN,and defines the indexes of scheduling time and link quality,and solve problem of routing and wavelength assignment by means of integer programming,meanwhile algorithm of improved binary particle swarm optimization is used to realize effective scheduling of network resources.Experimental results show that the performance of the proposed method is superior to that of traditional classic algorithms on indexes of recovery time,blocking probability and resource utilization.Overall,the method improved the efficiency of fault repair from model design to algorithm application.
