Service route selection method and device in electric power communication network

Abstract

The invention provides a service route selection method and device in an electric power communication network. The method comprises the following steps: according to a topological structure of the electric power communication network, distributing a path for an arriving service, adopting a Dijsktra algorithm to acquire a path set of the arriving service; traversing the path set, calculating a full-service risk degree, a full-network risk degree, a full-network load balance degree and a full-network risk balance degree responding to the path; rejecting the path set according to the full-service risk degree, the full-network risk degree and the full-network load balance degree until traversing all paths in the path set and acquiring a target path set; if the target path set is non-null, then performing ascending sort on the paths in the target path set, and selecting a first path as a service route; and making the arriving service to forward a message according to the service route. The service route selection method and device in the electric power communication network provided by the invention can uniformly distribute the service routes in the electric power communication network and avoid the concentrated risk distribution.

Description

Technical field [0001] The invention relates to a route selection technology for a power communication network, in particular to a method and device for selecting a business route in the power communication network. Background technique [0002] The power system is an electric energy production and consumption system composed of power plants, transmission and transformation lines, power supply and distribution stations, and electricity consumption. As an important infrastructure of the power system, the power communication network is designed to ensure the safe and stable operation of the power system. As a result, the business in the power communication network is closely related to the production, dispatch and control of the power system. With the rapid development of the electric power communication network, there is an increasing need for more and more frequent collaborative communication among the many subsystems of the electric power system. Therefore, a large number of ser...

[0004] However, although the above algorithm realizes the balanced deployment of services from the perspective of bandwidth, and selects a path with the largest bandwidth to execute data, it is very likely to lead to excessive concentration of the risk distribution of the selected service route, which will easily lead to abnormal or abnormal business channels. faults, resulting in operational risks of the power communication network
