Power Communication Network Fault Recovery Algorithm Based on Service Characteristics and Node Reliability

摘要

In order to solve the problem that the recovered service is re-disrupted due to the allocation of low-reliability network resources for power service during fault recovery, this paper proposes a power communication network fault recovery algorithm based on service characteristics and node reliability in SDN environment. The algorithm includes three steps of performing the descending ordering of the service to be restored based on the service feature, calculating the reliability of the node based on the alternative probability of the node and descending the order, and sequentially recovering the service from the set of services to be restored. In the simulation experiment part, compared with the traditional algorithm, it is verified that the proposed algorithm improves the fault recovery rate and the revenue of the power communication network, and has great practical application value.
