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.

     - 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.
