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 c

Embodiment 1

[0045] like figure 1 , figure 2 As shown, the method for checking and optimizing a single point of failure of a power communication service of the present invention includes the following steps:

[0046] (1) Establish a physical link model of the communication network, including all network element equipment of the entire communication network, as well as the name of the optical cable segment interconnected between each network element, the length of the optical cable, and the occupied optical core resources;

[0047] (2) Analyze the full amount of service information of the communication network management server, obtain service type information and service logic channel routing information according to the keywords in the service configuration information, and establish a service set to be checked, wherein the service set to be checked can be divided into the following according to service types Business subsets: protection, security control, automation, dispatch telephone...

Embodiment 2

[0100] On the basis of Embodiment 1, the difference is that: the principle of setting route optimization selects the principle of minimum transit, setting k1=1, k2=k3=0; in the physical independent route set, the total weight of each route is calculated, that is, The sum of the weights of each section of the entire route defines the total weight W=∑Pi,j; according to the minimum transit principle selected by the user, the optimal route for the user's needs is calculated.

Embodiment 3

[0102] On the basis of Embodiment 1, the difference is that: the reachable route search uses a depth-first algorithm, traverses the adjacency matrix, stops when it encounters an end node or branches into a loop from the starting point, and reaches the target node for recording. Thereby, the path of reachable routes is obtained, and a set of reachable routes is established.

[0103] Using the depth-first algorithm, the nodes are not fully retained, and the expanded nodes are popped and deleted from the database. Generally, the number of nodes stored in the database is the depth value, which takes up less space. When there are many nodes in the search tree, other methods are used. It is easy to generate memory overflow, and it is more convenient to use the depth-first algorithm to solve.

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.
