Risk Balancing Routing Assignment Mechanism Based on Service Importance

The power communication network service plays an important role in the production and operation of the power system. Therefore, the power communication department needs to solve the problem that how to reduce the security risk of the bearer service and distribute the service path properly. However, most of the existing algorithms do not take the difference of service importance into account, thus resulting in unbalanced traffic channel segment distribution and increase of the overall network risk. In this paper, a risk balancing routing assignment mechanism based power communication network service importance (SIRBRM) is proposed. And the analytic hierarchy process (AHP) is introduced and a model of risk balancing routing assignment problem is established. Then the routing decision based on the principle of maximum and minimum fairness constraint can choose the optimal route for the service. Finally, the simulation is carried out based on the power communication network topological data of a certain prefecture-level city. Simulation results show that compared with the other two methods, the SIRBRM can effectively reduce the link risk and the overall network risk, make the service distribution more uniform, and reduce the operational risk caused by excessive concentration of the service on some specific links. SIRBRM has broad application prospects in the existing routing optimization and future arrangements for new business methods.
