Embodiment 1

[0076] This embodiment provides a service routing addressing method for service operation of electric power communication network, please refer to figure 1 , The method includes:

[0077] Step S1: Jointly model the physical layer, network topology layer and business organization layer of the electric power communication network, the service set is S={s1,s2,...,sh}, the electric power communication network includes n nodes and h business paths , Where n and h are positive integers.

[0078] Specifically, this embodiment defines the electric power communication network as a power undirected network through graph theory related theories. While constructing the electric power communication network, the following processing is required:

[0079] (1) Different levels in the power communication network, such as the cross-regional core layer, backbone layer, and control layer. In these three layers, different levels of sites (including plants and data dispatch centers) are abstracted into n...

Abstract

The invention discloses a service routing addressing method for service operation of a power communication network. Firstly, modeling is carried out on a power communication network; a chromosome coding mode based on priority is adopted; the service running state of the communication network is encoded; decoding is carried out by using a decoding mode corresponding to the code to obtain a servicepath set, then joint analysis is carried out on vulnerability factors of nodes and links in a physical layer, a network topology layer and a service organization layer to obtain a comprehensive vulnerability evaluation index of the power communication network, and an objective function and constraint conditions are set according to the comprehensive vulnerability evaluation index of the power communication network; and finally, the set target function is taken as a target optimization function of a genetic algorithm, the service route is optimized by adopting the genetic algorithm according tothe constraint condition, and the service route meeting the condition is selected from the service route set. According to the invention, the addressing efficiency can be improved, and the addressingeffect is improved.

Description

Technical field [0001] The present invention relates to the technical field of electric power communication, in particular to a service routing addressing method for service operation of electric power communication network. Background technique [0002] With the complexity of the power communication network structure and the diversification of services, the efficient, safe and stable operation of the power communication network is becoming more and more important. [0003] For the different application scenarios of the power communication network, the traditional method is to increase the redundancy of the infrastructure, double-device protection or even multi-device protection for the equipment passing by the important business, or add new sites and optical fiber links to the power communication network Road construction to improve network connectivity, but requires huge capital investment; therefore, it is necessary to optimize the business routing addressing of the power commun...
