This document generalizes the applicability of the pseudowire (PW)
Associated Channel Header (ACH), enabling the realization of a control
channel associated to MPLS Label Switched Paths (LSPs) and MPLS Sections
in addition to MPLS pseudowires. In order to identify the presence of
this Associated Channel Header in the label stack, this document also
assigns one of the reserved MPLS label values to the Generic Associated
Channel Label (GAL), to be used as a label based exception mechanism.
Working Group Summary
No real controversies, though quite a bit of discussion on the number of
experimental code points.
The level of the review is very good. The document has been reviewed by
the ITU-T ad hoc Team on MPLS-TP.
Loa Andersson is the Document Shepherd for this document.
Adrian Farrel is the Responsible Area Director.
