A new Request for Comments is now available in online RFC libraries. RFC 7579 Title: General Network Element Constraint Encoding for GMPLS-Controlled Networks Author: G. Bernstein, Ed., Y. Lee, Ed., D. Li, W. Imajuku, J. Han Status: Standards Track Stream: IETF Date: June 2015 Mailbox: gregb@grotto-networking.com, ylee@huawei.com, danli@huawei.com, imajuku.wataru@lab.ntt.co.jp, hanjianrui@huawei.com Pages: 28 Characters: 62347 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-ccamp-general-constraint-encode-20.txt URL: https://www.rfc-editor.org/info/rfc7579 DOI: http://dx.doi.org/10.17487/RFC7579 Generalized Multiprotocol Label Switching (GMPLS) 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. This document is a product of the Common Control and Measurement Plane Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
