The IESG has approved the following document: - 'Revised Definition of The GMPLS Switching Capability and Type Fields' (draft-ietf-ccamp-swcaps-update-03.txt) as Proposed Standard
This document is the product of the Common Control and Measurement Plane Working Group. The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ccamp-swcaps-update/ Technical Summary GMPLS provides control for multiple switching technologies, and hierarchical switching within a technology. GMPLS routing and signaling use common values to indicate switching technology type. These values are carried in routing in the Switching Capability field, and in signaling in the Switching Type field. While the values used in these fields are the primary indicators of the technology and hierarchy level being controlled, the values are not consistently defined and used across the different technologies supported by GMPLS. This document is intended to resolve the inconsistent definition and use of the Switching Capability and Type fields by narrowly scoping the meaning and use of the fields. This document updates any document that uses the GMPLS Switching Capability and Types fields, in particular RFC 3471, RFC 4202, RFC 4203, and RFC 5307. Working Group Summary: Nothing of note. Good support by the WG. Document Quality: This document updates the definitions for the Switching Type field to be consistent and deprecates three previously defined switching types. For existing implementations, the primary impact of this document is deprecating the use of PSC-2, 3 and 4. At the time of publication, there are no known deployments (or even implementations) that make use of these values so there is no compatibility issues for current routing and signaling implementations.

RFC Editor Note Abstract OLD This document updates any document that uses the GMPLS Switching Capability and Types fields, in particular RFC 3471, RFC 4202, RFC 4203, and RFC 5307. NEW This document updates all documents that use the GMPLS Switching Capability and Types fields, in particular RFC 3471, RFC 4202, RFC 4203, and RFC 5307. END Section 1 OLD In particular this document proposes deprecating the use of the Switching Types as an identifier of hierarchy levels within a switching technology, and limit its use to identification of a per-switching technology SCSI field format. NEW In particular this document deprecates the use of the Switching Types as an identifier of hierarchy levels within a switching technology, and limits its use to identification of a per-switching technology SCSI field format. END Section 1.1 (end) s/ Descriptor .../ Descriptor./ Section 5 OLD IANA needs to deprecate and redefine the related registry NEW IANA needs to deprecate some values and redefine the related registr END
