Embodiment 1

[0076] This embodiment provides a service routing addressing method oriented to the service operation of the 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 power communication network. The business set is S={s1, s2,...,sh}, and the power communication network includes n nodes and h business paths , where n and h are positive integers.

[0078] Specifically, this implementation defines the power communication network as a right-to-direction network through graph theory. When constructing a 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. Sites of different levels in these three layers (including each plant station and data dispatching center) are abstracted into nodes of the power...

Abstract

The invention discloses a service routing addressing method oriented to the service operation of the electric power communication network. Firstly, the electric power communication network is modeled, and the service operation state of the communication network is coded by adopting a chromosome coding method based on priority, and then Using the decoding method corresponding to the encoding to decode, the business path set can be obtained, and then the vulnerability factors of nodes and links in the physical layer, network topology layer and business organization layer are jointly analyzed to obtain a comprehensive power communication network. Vulnerability assessment index, and then according to the comprehensive vulnerability assessment index of the power communication network, set the objective function and constraint conditions; finally, the set objective function is used as the objective optimization function of the genetic algorithm, and the service routing is optimized by the genetic algorithm according to the constraint conditions. Select qualified service paths from the set of service paths. The invention can improve the addressing efficiency and improve the addressing effect.

Description

technical field [0001] The 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 structure of the power communication network and the diversification of services, the efficient, safe and stable operation of the power communication network is becoming more and more important. [0003] For different application scenarios of the power communication network, the traditional method is to increase the redundancy of the infrastructure, to implement dual-device protection or even multi-device protection for the equipment that important services pass through, or to add new sites and optical fiber links to the power communication network. Road construction improves network connectivity, but requires huge capital investment; therefore, it is necessary to optimize the routing and addressing of pow...
