The IESG has approved the following document: - 'An Inband Data Communication Network For the MPLS Transport Profile ' <draft-ietf-mpls-tp-gach-dcn-06.txt> as a Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Ross Callon and Adrian Farrel. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-mpls-tp-gach-dcn-06.txt Technical Summary The Generic Associated Channel (G-ACh) has been defined as a generalization of the pseudowire (PW) associated control channel to enable the realization of a control/communication channel associated with Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs), MPLS PWs, MPLS LSP segments, and MPLS sections between adjacent MPLS-capable devices. This document describes how the G-ACh may be used to provide the infrastructure that forms part of the Management Communication Network (MCN) and a Signaling Communication Network (SCN). Collectively, the MCN and SCN may be referred to as the Data Communication Network (DCN). This document explains how MCN and SCN messages are encapsulated, carried on the G-ACh, and demultiplexed for delivery to the management or signaling/routing control plane components on an MPLS-TP node. It should be noted that the use of the G-ACh to provide connectivity for the DCN is intended for use only where the MPLS-TP network is not capable of encapsulating or delivering native DCN messages. Working Group Summary The document is part of the MPLS-TP project, the cooperation between IETF and ITU-T to specify an MPLS transport profile. The working group has consensus on the document, and the ITU-T has indicated that it supports the publication. Document Quality We have seen test implementations of the G-ACh and received feedback, but we know of no current implementations of the MCC or SCC. We have been informed by two vendors of their intent to implement soon. The document review has been substantial. Considerable input to early revisions was received from MPLS WG participants, from participants in the MPLS-TP project. The WG last call was liaised to the ITU-T, and the final revision (including resolution to WG last call comments) was supported by the ITU-T in a liaison.(see PROTO writeup by Loa Andersson in the ID tracker). Personnel Loa Andersson is the Document Shepherd. Ross Callon is the responsible area director. RFC Editor Note Section 4 OLD The G-ACh provides a virtual link between MPLS-TP nodes and might be used to induce many forms of security attack. Protocols that operate over the MCN or SCN are REQUIRED to include adequate security mechanisms and implementations MUST allow operators to configure the use of those mechanisms. NEW The G-ACh provides a virtual link between MPLS-TP nodes and might be used to induce many forms of security attack. The MPLS data plane does not include any security mechanisms of its own, therefore it is important that protocols using the DCN apply their own security. Protocols that operate over the MCN or SCN are REQUIRED to include adequate security mechanisms and implementations MUST allow operators to configure the use of those mechanisms.
