  2. Contents • Introduction • Background • Overview of operation • Way Forward • Comments/Questions

  3. Introduction - General • XCON Conference Framework almost complete as an XCON WG item • Understandably discussions have primarily focused on voice/video conferences • Framework introduces generic topics applicable to multiple signalling protocols and media types • Conference Object • Cloning Tree Model • MSRP as an alternative media type provides a valid proof point for the XCON Framework

  4. Introduction - MSRP • MSRP has matured as a standard • Recognition as the primary session based Instant Messaging technology • Provides an ideal media type for XCON Framework proof point (from previous slide) • IM Conferencing has an important role to play in future XCON architectures • In conjunction with other media (e.g. Voice, Video) • Standalone (e.g. Chat Rooms)

  5. Document Background • -02 presented at IETF-64 as a ‘Work-In-Progress’ • Introduced the concept of an XCON Conference Object with MSRP as the media type • MSRP is peer-to-peer protocol • XCON Conference System acts as MSRP End Point to all participating clients (see diagram on next slide) • Interaction between Client  Server is a 1:1 mapping

  6. Document Overview • MSRP connection to Conference System is used to send messages to a Conference Instance

  7. Document Overview • MSRP SEND message is then distributed to relevant participants of the Conference Instance

  8. Changes since -02 version • Added text clarifying how the MSRP conferencing requirements (per the draft-niemi-simple-chat) are met • Updated references • Added text and examples describing the basic operations: create, join, delete • Added text and examples for advanced operations: Text sidebars and private messaging

  9. Document Scope • Document in ‘no-way’ impacts the core MSRP protocol • Simply applies XCON Framework principles • Document complements draft-niemi-simple-chat-06 by focusing on the framework aspects rather than the media details. • Nicknames aren’t addressed as they’re deemed a more general problem.

  10. Document Issues/discussion • Document complements draft-niemi-simple-chat-06 by focusing on the framework aspects rather than the media details. • Should we combine the two docs for a comprehensive solution? • Nicknames aren’t addressed as they’re deemed a more general problem. • Should we work towards a general solution or define a solution specific to MSRP?

  11. Way Forward • Update document based on feedback: • Editorial nits • Clarification around scope per issues discussion • Put in the queue for adding to XCON charter once other WG deliverables are completed

  12. ANY COMMENTS/Questions?
