A verification and optimization method and system for a single point of failure in power communication services

Abstract

The invention discloses a method for checking and optimizing single-point failures of electric power communication services, which establishes a physical link model of a communication network; analyzes and communicates a full amount of business information, and establishes a set of services to be checked; obtains service logic channel routing information according to the service information to be checked, and obtains the described Routing information of business physical channels to find potential single-point failure points; rebuild the logical link model of the communication network, add information on the proportion of optical path resources, mark the existence of physical links with the same route in the logical link, and establish a set of logical links with the same route ; Routing optimization for hidden danger points of single point of failure. The beneficial effect of the present invention is to quickly identify and find out the hidden danger of a single node failure, through the optimal routing calculation module, to provide optimization suggestions for the optimal routing according to the needs of different users, so as to accurately eliminate the hidden danger of single point failure; Provide references to avoid missed checks, save a lot of manpower and material resources, improve work efficiency, and have a high degree of automation.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a method and system for checking and optimizing single point failures of power communication services. Background technique [0002] As the infrastructure of the power grid, the power communication network carries important services such as relay protection, automation, and dispatch calls. It is the basic guarantee for the safe operation of the power grid and an important support for the continuous development of enterprise informatization. With the continuous construction of the global energy Internet, smart grid, and the rapid development of big data and other technologies, the power communication business is becoming more and more abundant, which puts forward higher requirements for the robustness and reliability of the power communication network. [0003] At present, power communication transmission usually adopts protection methods such as SNCP (Su...

Problems solved by technology

The selection of the main and backup channel routes is usually automatically produced by the network management or manually configured by technicians. The routes automatically generated in the network management system are based on the principle of mutual exclusion of routes at the logical level, and cannot identify the routing conditions of the channels at the physical link level, resulting in user traffic The main and backup routes have the same route, same optical cable, same site or same equipment at the physical link layer. If the optical cable is interrupted or the equipment fails, it will cause the failure of the power communication network, that is, there is a hidden danger of single node failure, which will seriously affect the power supply. Safe and Stable Operation of Communication Network

[0004] At present, single-node troubleshooting and routing optimization methods rely on the experience of technicians, require manual statistical analysis, have a low degree of automation, and require a lot of manpower and material resources, and the accuracy of troubleshooting is low, inspection and maintenance take a long time, and inspection speed is slow , high maintenance costs
