[0011] At present, in the electric power optical fiber private network, one optical fiber only carries one 2M relay protection service, and the resource occupancy rate is high but the utilization rate is extremely low. How to improve the optical fiber resource utilization rate of the electric power optical fiber communication network while ensuring The reliability of the real-time control business of the production and operation of the power grid with the highest level of importance carried by the private power network will not be affected, which is a problem that has yet to be solved

Embodiment Construction
[0045] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0046] Such as figure 2 As shown, this embodiment mainly includes the following steps:
[0047] 1) Input network topology information, business demand information, link capacity information and the number of the power cable to which the link belongs;
[0048] 2) Classify and prioritize the services carried by the power communication network according to their importance;
[0049] 3) Judging whether the business is all arranged for work routing and protection routing, if not, proceed to step 4); if yes, then end;
[0050] 4) take out the business that does not arrange the route from the business list of prioritization described in step 2);
[0051] 5) determine whether the working route and protection route of the business in step 4) have been processed, and if not processed, then proceed to step 6); if processed, the...

The invention is a fiber communication network service route configuration method used in electric power. The services loaded on the electric power communication network are classified and sequenced based on priorities according to importance. The services are removed in order to carry out a work route path search. After the path search is successful, a path search is carried out towards the protection route in the protection manner set by the service. If the path search of the protection route is successful, then it is determined that the service is successfully routed. The invention is directed to the electrical network operation control service which has the highest priority grade and puts forward a specially-used protection route method against cable breaking risks. According to the invention, the electric power fiber network can satisfy the reliability bearing requirements from different electrical network services and the network resource utilization rate of the whole network is raised as well. The invention provides special protection towards A type services, the sustainable communication capacity of the electric power fiber communication network in great natural disasters is improved and the high availability of the important electrical network production control services loaded on the electric power communication network is ensured on occasions of cable breaking faults.
Description
Technical field: [0001] The invention relates to the field of optimization and design of electric power communication systems, and specifically designs a service routing configuration method of an electric power dedicated optical fiber communication network. Background technique: [0002] The configuration of the service route of the communication network refers to the allocation of the main route and the protection route for the service. The design of the protection route is closely related to the availability of network resources and services. The following are two commonly used methods for designing the working route and the protection route. [0003] 1. Node separation and link separation [0004] Link separation means that the protection route of a service cannot pass through all the links passed by the working route; node separation means that the protection route of a service does not pass through the nodes passed by the working route except that the starting node is ...
