Fault Recovery of Network Slice based on Cloud and Optical Integration

Traditional fault recovery methods generally consider only one aspect of the network or cloud, which can only be a local optimal solution. Under the new background of cloud and optical integration, how operation and maintenance personnel can achieve the global optimal solution of fault recovery with a global vision is a problem worth studying. This study proposes the joint slice fault recovery (JSFR) algorithm that recovers the fault by comprehensively considering the respective weights of cloud and optical in the case of global vision. Compared with the traditional random recovery algorithm and greedy recovery algorithm, the performance of JSFR can be improved by 21.8% and 4.4% respectively.
