Abstract:
1. A method for automatically implementing Tandem Concatenation Monitoring, TCM, comprising: requesting, by a sub-network, a network management system for a required number of TCM levels; assigning, by the network management system, available TCM levels to a pair of network nodes in the sub-network; performing, by the pair of network nodes in the sub-network, TCM processing, mapping TCM use information into a corresponding overhead, transferring the TCM use information together with TCM overhead information downstream, and reporting TCM information to the network management system, wherein the TCM information comprises TCM monitored information, TCM use information, and TCM operation information; by comparing the TCM use information and the TCM operation information, determining the TCM levels that pass through each network node and have been used, and which level of TCMi each network node is processing; and extracting, by the network management system, TCM monitored information, determining transmission quality of each of the sub-networks, and locating a network failure.
