A network risk assessment methodology for power communication business

To improve the power communication network risk assessment techniques, we proposed a network risk assessment method for power business. The method is based on the risk assessment relationship model consisted of communication network and power network. According to the risk caused by different levels business faults in physical link layer, network topology layer and business layer, the model uses probabilistic methods to calculate the loss of business caused by network element fault, and then comes out the network risk for business. The simulation results show that this method is easy to understand, and can be deployed to identify the business weaknesses through the risk assessment results, targeted to enhance link reliability or adjust service deployment, reducing the risk of the network.
