<p>A method for implementing tandem concatenation monitoring TCM automatically includes: each sub network applies to a network management for a level of needing performing TCM (S01); the network management distributes the available levels to network node pairs in the sub networks (S02); the network node pairs in the sub networks perform TCM processing, map the TCM use information to the corresponding overhead, transfer it together with the TCM overhead information to the down stream, and report the TCM information to the network management (S03); the network management refreshes the TCM distribution diagram, extracts the corresponding TCM information, determines the transmission quality of each sub network, and locates the network failure (S04). Also an apparatus for implementing tandem concatenation monitoring TCM automatically comprises a controller, a TCM generator and a TCM terminator, which implement TCM function automatically together. The invention overcomes the defects that the network static configuration has poor flexibility and is complex, and improves the flexibility of TCM procession.</p> |
