The IESG has received a request from the Common Control and Measurement Plane WG (ccamp) to consider the following document: - 'General Network Element Constraint Encoding for GMPLS Controlled Networks' <draft-ietf-ccamp-general-constraint-encode-16.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-01-17. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Generalized Multiprotocol Label Switching can be used to control a wide variety of technologies. In some of these technologies network elements and links may impose additional routing constraints such as asymmetric switch connectivity, non-local label assignment, and label range limitations on links. This document provides efficient, protocol-agnostic encodings for general information elements representing connectivity and label constraints as well as label availability. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses.
