Abstract
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).
