The IESG has approved the following document: - 'OSPF-TE Extensions for General Network Element Constraints' (draft-ietf-ccamp-gmpls-general-constraints-ospf-te-10.txt) as Proposed Standard This document is the product of the Common Control and Measurement Plane Working Group. The IESG contact persons are Alia Atlas and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ccamp-gmpls-general-constraints-ospf-te/ Technical Summary 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., SONET/SDH, 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. Working Group Summary This topic been discussed in the WG for a very long time, perhaps 6 years. Support for the work has been tepid, but there are multiple sets of contributors who would like to see the work result in proposed standards. Document Quality The base GMPLS routing protocol has been implemented. The extensions defined in this document are compatible with earlier implementations. Multiple implementors have stated their intent to implement, or have stated that they have already implemented, the mechanisms defined in this document.
