Tunnel follow-up message for transparent clock

摘要

A method for handling at least one encapsulated synchronization message by a tunnel node including a transparent clock, includes generating a signature from the encapsulated synchronization message and generating, or updating if it has already been generated, a tunnel follow-up message. The tunnel follow-up message includes the encapsulated synchronization message signature. The method further includes measuring the encapsulated synchronization message residence time across the tunnel node, and updating the correction field of the tunnel follow-up message with the measured residence time.

1. A method for handling at least one encapsulated synchronization message by a tunnel node including a transparent clock, the method comprising:
generating at least one encapsulated synchronization message signature from the at least one encapsulated synchronization message; generating a tunnel follow-up message, or updating the tunnel follow-up message when the tunnel follow-up message has already been generated, the tunnel follow-up message including the at least one encapsulated synchronization message signature, and the tunnel follow-up message being included within a modified operations administration and maintenance (OAM) label switch path (LSP) tracercute message; measuring at least one encapsulated synchronization message residence time across the tunnel node; and updating, at an intermediate tunnel node, a correction field of the tunnel follow-up message with the measured at least one encapsulated synchronization message residence time.
