A method and system for checking and optimizing single point fault of electric power communication service

Abstract

The invention discloses a method for checking and optimizing a single point fault of an electric power communication service. The method comprises the steps of establishing a physical link model of acommunication network; analyzing the total amount of service information, and establishing the service set to be checked; obtaining the service logical channel routing information according to the service information to be sorted out, obtaining the service physical channel routing information, and searching for a single point of hidden trouble; reconstructing the logical link model of communication network, adding optical path resource occupancy ratio information, marking the physical link co-routing situation in the logical link, and establishing the logical link co-routing set; and routing optimization of a single point of failure is carried out. The method of the invention has the advantages that the hidden trouble of the single node is quickly identified and found, and the optimizationsuggestion of the optimal route is provided according to the requirements of different users through the optimal route calculation module, so as to accurately eliminate the hidden trouble of the single point of the fault; the optimization proposal can provide reference to the staff, avoid missing the situation, save a lot of manpower and material resources and improve work efficiency, and is highin 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 a system for checking and optimizing a single point of failure of a power communication service. Background technique [0002] As the infrastructure of the power grid, the power communication network carries important services such as relay protection, automation, and dispatching telephone 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 technologies such as big data, power communication services are increasingly enriched, which puts forward higher requirements for the robustness and reliability of power communication networks. [0003] At present, power communication transmission usually adopts SNCP (Sub-Network Connection Prot...

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, and manual statistical analysis is required. The degree of automation is low, and it requires a lot of manpower and material resources, and the accuracy of troubleshooting is low, and inspection and maintenance take a long time. Inspection speed is slow , high maintenance costs
