TCM path search method, TCM path creaetion method, path search management system, and path creation management system

摘要

A Tandem connection monitoring (TCM) path search method, a TCM path creation method, a path search management system, and a path creation management system are provided. The source end TCM mode and the sink end TCM mode at a single level of each node in an Optical Channel Data Unit-k (ODUk) path are acquired; and a TCM path at the single level between nodes in the ODUk path is calculated according to the source end TCM mode and the sink end TCM mode at the single level of each node that are acquired. TCM level information and the sink end TCM mode of a second node for TCM path creation between a first node and the second node are acquired by specifying the first node and the second node; and a TCM path between the first node and the second node that are specified is created and stored.

1. A Tandem connection monitoring (TCM) path search method, comprising:
acquiring the source end TCM mode and the sink end TCM mode at a single level of each node in an Optical Channel Data Unit-k (ODUk) path; storing the source end TCM modes and the sink end TCM modes of the nodes according to a sequence of nodes that the ODUk path passes through; and calculating a TCM path at a single level between nodes in the ODUk path according to the source end TCM mode and the sink end TCM mode at the single level of each node that are acquired, wherein the calculating comprising:
traversing source end TCM modes and sink end TCM modes of all nodes at the single level of the ODUk path according to the sequence of the nodes that the ODUk path passes through, and when traversing a first node whose source end TCM mode being the OPERATIONAL mode, determining the node as a start point of the TCM path at the single level between the nodes in the ODUk path;continuing to traverse nodes after the first node whose source end TCM mode being the OPERATIONAL mode according to the sequence of the nodes that the ODUk path passes through; wherein when traversing a first node whose sink end TCM mode being the OPERATIONAL mode or the MONITOR mode, acquiring a TCM path at the single level between the nodes in the ODUk path from the first node whose source end TCM mode being the OPERATIONAL mode to the first node whose sink end TCM mode being the OPERATIONAL mode or the MONITOR mode.
