In May 2001 the TEWG adopted the development of the requirements and necessary protocol extensions for Diff-Serv TE. Upon completion, TEWG was to notify the various protocol WGs of the proposal to allow review of the proposed protocol changes (if any). This note serves that purpose. Please find the pointer for the protocol specification draft below and review the proposed changes required in the routing and signaling protocols. A WG last call on the protocol draft will start by separate email to the TEWG. Be sure to follow-up with any discussion to the te-wg list. http://www.ietf.org/internet-drafts/draft-ietf-tewg-diff-te-proto-03.txt It specifies extensions outlined as follows: - IGP Reuse of unreserved bandwidth sub-tlv to carry BW available per TE-Class - IGP Optional use bandwidth constraints sub-tlv - IGP Optional use local overbooking multiplier sub-tlv - RSVP Class Type Object for signaling class-types other than 0. - RSVP Diffserv TE error codes The protocol supports the use of a variety of different bandwidth constraint models. The following drafts are examples listed here for reference only. http://www.ietf.org/internet-drafts/draft-ietf-tewg-diff-te-russian-02.txt http://www.ietf.org/internet-drafts/draft-lefaucheur-diff-te-mam-00.txt http://www.ietf.org/internet-drafts/draft-ash-mpls-dste-bcmodel-max-alloc-resv-01.txt Also for reference, the requirements are developed and with RFC-ED now. http://www.ietf.org/internet-drafts/draft-ietf-tewg-diff-te-reqts-07.txt
