Abstract

The invention discloses a method and system for transport network co-routing analysis. The method comprises the steps: obtaining a topological structure and an optical route of the transmission network, and enabling the topological structure to consist of links; constructing an optical path group based on the association of the optical path route and the link; analyzing the optical path group on the basis of FP-growth to obtain frequent routes and frequent patterns of the frequent routes; analyzing the condition of the same route according to the frequent routes and the frequent patterns thereof. The analysis of the same route is based on the association of an optical route and a link, so that the hit rate of an analysis result can be improved, and the efficiency and coverage rate of the same route analysis are improved; the same route analysis is carried out through the FP-growth algorithm, so that the efficiency of the same route analysis can be improved.

Description

technical field [0001] The invention relates to the technical field of transmission network, in particular to a method and system for analyzing the same route of transmission network. Background technique [0002] The same routing of the transmission network means that two or more transmission networks go through the same physical medium, such as a multi-core optical cable or the same optical fiber distribution frame. Once one of the transmission networks is interrupted, the other transmission network will also be interrupted. Interruption will easily cause the entire transmission network of the same route to be interrupted, resulting in service interruption, affecting user experience, and causing losses to users and operators. Therefore, the principle of multi-routing protection for important services should be observed during the laying of optical fibers, and finding and eliminating the same route is an important task of network resource management. The transmission netwo...
