Abstract

The embodiment of the invention provides a path grouping method, a path grouping device and a path grouping system. The method comprises the following steps of: selecting a source network element and a destination network element and searching for all optical channel data unit-k (ODUk) paths between the source and destination network elements; obtaining the distribution conditions of the ODUk paths, and if the plurality of ODUk paths are born on different optical fibers, dividing each ODUk path into corresponding working groups or protection groups according to preset protection relationships between working groups M and protection groups N respectively; and if the path segments of at least two of the plurality of ODUk paths are partially born on the same optical fiber, dividing each ODUk path into the corresponding working groups or protection groups according to the preset protection relationships between the working groups M and the protection groups N and different ODUk path bearing wavelengths, wherein M and N are natural numbers. The embodiment of the invention improves grouping efficiency in M protection N optical channel data unit-k sub-network connection (MpN ODUk SNC) and simultaneously reduces error probability in the grouping.

Description

technical field [0001] The present invention relates to the communication field, in particular to a path grouping method, device and system. Background technique [0002] In the optical transport network system, when the transmitted service is interrupted, it is necessary to switch the service from the working channel to the protection channel in a short period of time through protection switching, so as to minimize the impact on customers. [0003] The types of protection can be divided into multiple types according to different classification methods. For example, according to the protection networking form, it can be divided into linear protection and ring protection, and according to the service level of protection, it can be divided into optical layer protection and electrical layer protection. The M ratio N Optical Channel Data Unit Subnetwork Connection (MpN ODUk SNC, M proportion N Optical channel Data Unit-k Sub-Network Connection) belongs to the linear protection s...
