A new Request for Comments is now available in online RFC libraries. RFC 7580 Title: OSPF-TE Extensions for General Network Element Constraints Author: F. Zhang, Y. Lee, J. Han, G. Bernstein, Y. Xu Status: Standards Track Stream: IETF Date: June 2015 Mailbox: zhangfatai@huawei.com, leeyoung@huawei.com, hanjianrui@huawei.com, gregb@grotto-networking.com, xuyunbin@mail.ritt.com.cn Pages: 12 Characters: 25189 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-ccamp-gmpls-general-constraints-ospf-te-10.txt URL: https://www.rfc-editor.org/info/rfc7580 DOI: http://dx.doi.org/10.17487/RFC7580 Generalized Multiprotocol Label Switching (GMPLS) can be used to control a wide variety of technologies including packet switching (e.g., MPLS), time division (e.g., Synchronous Optical Network / Synchronous Digital Hierarchy (SONET/SDH) and Optical Transport Network (OTN)), wavelength (lambdas), and spatial switching (e.g., incoming port or fiber to outgoing port or fiber). 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 describes Open Shortest Path First (OSPF) routing protocol extensions to support these kinds of constraints under the control of GMPLS. 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. Distribution of this memo is unlimited. This announcement is sent to the IETF-Announce and rfc-dist lists.
