Abstract

This paper proposed a network slice survivability algorithm based on multiple link failures to ensure the continuity of user services when underlying network multi-link failed. By distinguishing the types of services carried on slices, the physical nodes were sorted according to the importance of the nodes and mapped when the request of ultra-reliable and low latency communication slice arrived. Then the faulty link adopted the algorithm of multiple backup paths. It selected the paths that consume the least bandwidth resources to remap the failure links in sequence to ensure service continuity on the slice. When the request of enhanced mobile broadband slice arrived, it adopted the breadth first search node mapping algorithm to recover the faulty link through multiple backup paths. Simulation results show that the algorithm can improve the average mapping success rate of slice, ratio of long-term average benefits to costs, physical link utilization rate, failure restoration rate, and shorten the average failure restoration delay.
