Problems solved by technology
The routing protocol based on the shortest path does not consider the specific business requirements and the dynamic characteristics of the network when selecting the transmission path for the power service, so the shortest path is often not the optimal path

The invention discloses a method and a system for routing selection orienting to a power business. The method comprises the steps of: making corresponding marks on businesses of a power system, and adding the marks into a type control field of network control information; reading the type control field, and acquiring weighted values corresponding to the type control field from a weight list preset by a local router; and substituting the weighted values into a preset fitness function, and carrying out calculation according to a multi-constraint routing selection algorithm to acquire the final routing selection. With adoption of the method and the system disclosed by the invention, shortest routes and constraint conditions specific to the characteristics of the power business can be taken into comprehensive consideration so as to find out an optimal route meeting requirements of the characteristics of the power business, and the effects of optimizing network resources and balancing network load are achieved.
Description
technical field [0001] The invention relates to the field of power communication, in particular to a routing selection method and system for power services. Background technique [0002] The deepening of the reform of the electricity market and the improvement of the informatization level of the electricity industry have led to a rapid increase in the types and quantities of electricity services. The demand for bandwidth in electricity communication is increasing, and the requirements for reliability and delay are getting higher and higher. A router is often required when two computers that are not directly connected need to communicate across a network. Routers provide a means to carve out a path through mesh links. Due to limited network resources, traditional routing methods can no longer meet the communication requirements of power services. In order to better optimize network performance, it is necessary to consider routing methods for power services. [0003] Routing...
