Virtual Service Failure Recovery Algorithm Based on Particle Swarm in IPv6 Networks

In a IPv6 network environment, how to restore as many virtual network services as possible under the constraints of limited resources is an urgent problem to be solved. To solve this problem, this paper models the virtual network service recovery problem as a problem of maximizing the number of failed services recovery. A particle swarm-based virtual service failure recovery algorithm in IPv6 networks is proposed. The algorithm first constructs the faulty resource and virtual service as a two-layer correlation model. Secondly, the network resource recovery problem is modeled as a particle swarm problem, and the particle swarm optimization algorithm is used to solve it. In the experimental part, by comparing with existing algorithms, it is verified that the algorithm in this paper can recover more virtual network services that have failed.
