The IESG has approved the following document: - 'Operating Virtual Concatenation (VCAT) and the Link Capacity Adjustment Scheme (LCAS) with Generalized Multi-Protocol Label Switching (GMPLS)' (draft-ietf-ccamp-gmpls-vcat-lcas-13.txt) as a Proposed Standard This document is the product of the Common Control and Measurement Plane Working Group. The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ccamp-gmpls-vcat-lcas/ Technical Summary This document describes requirements for, and use of, the Generalized Multi-Protocol Label Switching (GMPLS) control plane in support of the Virtual Concatenation (VCAT) layer 1 inverse multiplexing data plane mechanism and its companion Link Capacity Adjustment Scheme (LCAS) which can be used for hitless dynamic resizing of the inverse multiplex group. These techniques apply to Optical Transport Network (OTN), Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH), and Plesiochronous Digital Hierarchy (PDH) signals. This document updates the procedures for supporting virtual concatenation in RFC4606. Working Group Summary This document received much attention and discussion in its early revisions. The document has been stable for quite some time, mainly needing revisions as part of the publication process. Document Quality There have been no public statements related to implementations. Personnel Deborah Brungard (db3546@att.com) is the Document Shepherd. Adrian Farrel (adrian.farrel@huawei.com) is the Responsible AD RFC Editor Note Abstract OLD This document describes requirements for, and use of, the Generalized Multi-Protocol Label Switching (GMPLS) control plane in support of the Virtual Concatenation (VCAT) layer 1 inverse multiplexing data plane mechanism and its companion Link Capacity Adjustment Scheme (LCAS) which can be used for hitless dynamic resizing of the inverse multiplex group.

LCAS can be used for hitless dynamic resizing of the inverse multiplex group. END --- Section 2.3 Final bullet paragraph. Replace dash with comma. OLD - Identification of the VCG and its associated members. This provides information that allows the endpoints to differentiate multiple VCGs and to tell what members - label switched paths (LSPs)- to associate with a particular VCG. NEW - Identification of the VCG and its associated members. This provides information that allows the endpoints to differentiate multiple VCGs and to tell what member, label switched paths (LSPs), to associate with a particular VCG. END --- Section 3 Replace all double dash (--) with single dash (-) --- Section 5. Caption to the figure should read Figure 1 - Conceptual containment relationship between VCG, VCAT calls, control plane LSPs, and data plane connections. --- Authors' Addresses OLD Email: diego.caviglia@(marconi.com, ericsson.com) NEW Email: diego.caviglia@ericsson.com END _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
