XCON WG IETF-73 Meeting Instant Messaging Sessions with a Centralized Conferencing (XCON) System draft-boulton-xcon-session-chat-02 Authors: Chris Boulton (firstname.lastname@example.org) Mary Barnes (email@example.com)
Overview XCON Conference Framework Done –Primarily focused on voice/video conferences XCON Protocol well underway Framework introduces generic elements applicable to multiple signalling protocols and media types –Conference Object –Cloning Tree Model Text-based “chat” as an alternative media type provides a valid proof point for the XCON Framework: –In conjunction with other media (e.g. Voice, Video) –Standalone (e.g. Chat Rooms) Independent of the work in SIMPLE WG: draft-ietf-simple- chat Protocol agnostic: Intent is to have no impact on existing IM/chat protocols
IM Client Conferencing System Basic Model Conferencing System is point of Inter-working for various IM chat clients – protocol agnostic
Current Status -02 updated to reflect move of detailed call flows to draft-barnes-xcon-examples Current focus of document is on the advanced operations. –Nicknames –Logging –History –Alternate Venue
Issues/Discussion 1.Suggestion to focus on ensuring applicability to other chat solutions (e.g., XMPP) rather than just MSRP –Proposal: ensure reference to chat protocol is fairly generic with examples such as XMPP (along with MSRP). –Consider applicability of currently proposed inter-working (e.g., XMPP-MSRP) Intent (of this doc) is that the conferencing server is a natural inter-working point 2.Suggestion to change terminology: XCON IM Sessions -> XCON Group chat
Issues/Discussion – Nicknames Proposal: Rather than define (in this WG) a very general Nickname mechanism, propose to scope nicknames unique within a conferencing system Nickname element is already defined in XCON data model Suggest conferencing system allocates nicknames: –When creating a user for XCON, add the option to specify a "nickname“ or infer that the inclusion of a proposed nickname implies a request for a nickname. –(In the future) IF the conferencing client has other mechanisms for getting a "nickname", conferencing system can handle checks for consistency. –In the case that the client is also using MSRP, client could just use the "nickname" provided when they setup the chat using XCON (when they create or update a userId)
Additional considerations 1.Nicknames: Look into nickname mechanisms of other protocols, such as XMPP, for consistency to minimize any inter-working problems Consider impact to call signaling protocols that might have nickname mechanisms – e.g., if a mechanism was added later to SIP. 2.Consider approaches for other features: Logging, History, Alternate Venue Again considering mechanisms used by other chat protocols – maximizing potential for inter-working is key.
Way Forward Need WG feedback Update document based on feedback Add details to chat call flows on use of Nicknames, since no normative protocol changes.
