Body |
We would like to inform you of the on-going work on version 2.0 of the Real Time Streaming Protocol (RTSP) in the IETF MMUSIC working group. RTSP 2.0 is intended to obsolete and replace RTSP 1.0. We plan to freeze any protocol feature changes by August 1st 2008 to complete RTSP 2.0 by the end of 2008. The latest Internet-Draft can be found at: http://tools.ietf.org/html/draft-ietf-mmusic-rfc2326bis The recently-published RFC 4775 [1] on "Procedures for Protocol Extensions and Variations" defines guideline procedures for cooperation between the IETF and outside entities on the extension of IETF protocols. It attempts to ensure that extensions will conform to the applicable architectural principles and technical criteria. Any development of protocol extensions and mechanisms related to RTSP would need to occur under the guidelines of RFC 4775. We would like to request that any RTSP extensions that may be in the scope of RTSP 2.0 or require IETF review (per RFC 4775) be discussed in IETF MMUSIC working group to seek wider community reviews and expert comments. We would therefore appreciate if you let us know if any group within your organization is working on technical specifications that make use of RTSP and if any protocol extensions are being considered. In the case extensions are being worked on, we would appreciate if you could provide any details (requirements, mechanisms, draft solution, etc.). Sincerely, Joerg Ott (MMUSIC co-chair) Jean-Francois Mule (MMUSIC co-chair) Reference: [1] Bradner S., Carpenter B., Narten T., "Procedures for Protocol Extensions and Variations", RFC 4775, December 2006. http://tools.ietf.org/html/rfc4775 |
