Abstract

The embodiment of the invention provides a business importance-based risk-balancing routing assignment method and system used for the technical field of routing assignment of a power communication network. The method comprises the steps of obtaining request business in the power communication network and determining the importance of the request business; determining k paths of the request business through a calculation method of the shortest path of a directed graph and a routing risk decision function built in advance according to the importance of the request business, wherein k is a positive integer; obtaining the k paths and determining the optimal path according to the maximum-minimum fairness constraint principle; and completing routing assignment according to the optimal path. Through the business importance-based risk-balancing routing assignment method provided by the embodiment of the invention, improvement of the actual pertinence of a risk balancing method is achieved and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of power communication network route distribution, in particular to a method and system for risk-balanced route distribution based on business importance. Background technique [0002] With the continuous development of the smart grid, the scale of the power communication network itself is getting larger and larger, and a large number of services are deployed to the live network according to actual needs, which in turn presents the characteristics of more and more frequent inter-system communication. As the physical network of the power system, the power communication network carries many business requirements such as operation management, stability and security, and is also closely related to production scheduling. However, in view of the randomness and frequent characteristics of network faults, service routing has certain risks. Therefore, how to quantify and analyze the risks of power communication serv...
