Technical Summary 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. Document Quality The level of the review is very good. The document has been reviewed by the ITU-T ad hoc Team on MPLS-TP. Personnel Loa Andersson is the Document Shepherd for this document. Adrian Farrel is the Responsible Area Director.
