METHOD AND APPARATUS FOR MULTI-INSTANCE CONTROL PLANE FOR DYNAMIC MPLS-TP TUNNEL MANAGEMENT VIA IN-BAND COMMUNICATION CHANNEL (G-ACH)

摘要

A dynamic tunnel management and signaling control plane protocol message is encapsulated in a data plane protocol encapsulating packet and communicated through a data plane channel to a destination label switching node. The destination label switching node extracts information from the dynamic tunnel management and signaling control plane protocol message from the data plane protocol encapsulating packet in the data plane, and performs a dynamic tunnel management process based on the extracted information. Optionally, the data plane channel is a generic associated channel (G-ACH).

1. A method for controlling a multi-protocol label switching transport protocol (MPLS-TP) network of label switching nodes that interface to a data plane, comprising
encapsulating a dynamic tunnel management and signaling control plane protocol message in a data plane protocol encapsulating packet; communicating the data plane protocol encapsulating packet to a destination label switching node, through a data plane channel in the data plane; extracting, at the destination label switching node, at least a portion of the dynamic tunnel management and signaling control plane protocol message from the data plane protocol encapsulating packet; and performing, at the destination label switching node, a dynamic tunnel management process based at least in part on the extracted at least a portion of the dynamic tunnel management control plane protocol message.
