Automatic searching method of power telecommunication network service channel route

Abstract

The invention discloses an automatic searching method of a power telecommunication network service channel route. The method comprises the following steps: incorporating basic parameters such as powertelecommunication network service specifications, working habit of power telecommunication network charging personnel into the route search, when a channel route type is optical-fiber multiplexing, successively searching a reachable route to a channel layer and a link layer, when the channel route type is optical-fiber dedicate use, searching a reachable route to an optical cable layer, so that acomplete route routing scheme can be provided. By adopting the automatic searching method, the selected route is ensured to be available by virtue of weight calculation, so that the situation that the calculated route cannot be used can be avoided; and meanwhile, a power telecommunication network N-1 principle is added in the spare route search, so that firm support is provided for the stable operation of the telecommunication network communication services, and the application prospect is good.

Description

technical field [0001] The invention relates to an automatic search method for a service channel path of an electric power communication network, and belongs to the technical field of automatic search for an electric power communication network path. Background technique [0002] The algorithm of automatic search for transmission path has been studied for a long time in the communication industry, and many domestic equipment manufacturers provide automatic path search function in EMS system. The path automatic search function provided by the EMS system can be divided into two categories. One is automatic channel connection. This function is mostly used in SDH channel connection. The other type is channel reachable path search. This function is based on the topological connection relationship between network elements and does not require available crossovers in the network elements. It searches the reachable path of topological connections from the target start point to the t...

Problems solved by technology

[0003] Generally speaking, the path search function of the traditional single mode cannot meet the design requirements of the power communication network scheme, mainly for the following points:

[0004] 1. The channel layer and link layer path search algorithms are not integrated, and cannot provide a complete path routing solution;

[0005] 2. The cable layer path search does not consider factors such as fiber core length, attenuation, and reserved spare fiber cores, and the path automatically calculated by the system cannot be used.
