Research on Invulnerable Routing optimization in Power Communication Backbone Network based on Link-Risk Equalization

Aiming at the invulnerability problem in the routing planning of power communication backbone network, this paper proposed an invulnerability routing optimization method based on link-risk equalization. Firstly, the link-risk equalization model of power communication backbone network is built. Then, based on the model, a network invulnerability routing optimization method is proposed, which takes the link-risk equalization and service transmission delay as the optimization objectives. Finally, the effectiveness of the proposed method is verified by experiments. Compared with the comparative method, the experiment shows that the proposed method can achieve effective risk balancing and improve the resilience of the power communication backbone network.
