IMO, this language is about right. I think there's still an open issue about where the SDP bit lives. Can we close on that? > > I think the arguments can be summarised as follows. > > - Keeping SDP in MMUSIC helps ICE focus on core ICE things > - MMUSIC has a lot of SDP knowledge needed to get things right I agree that a focused ICE group is a good idea. And there are already many "core" items the group will potentially start working on, so reducing the amount of extra items is in general a good idea. One point made at the Prague meeting for having also ICE SDP in ICE WG is that often SDP related to a protocol has been done jointly in the WG defining the protocol and SDP directorate has been used to make sure the SDP parts get proper review. On the other hand, now protocols using *ICE* would be done in different WGs, so perhaps MMUSIC with SDP should be considered as such. Regarding the charter text, I think it looks good, but I'm not sure if we need the first "history" paragraph. Maybe rather mentioned WebRTC and it's key role only with other protocols in the later paragraph?

Until recently the protocol had seen rather limited deployment. ICE was slow to achieve widespread adoption, as other mechanisms were alreadybeing used by the VoIP industry. This situation has changed drastically asICE is mandatory to implement in WebRTC, a set of technologies developed at the IETF and W3C to standardize Real Time Communication on the Web. >>> >>> Interactive Connectivity Establishment (ICE) is at the same time a NAT traversal technique, a multihomed address selection technique, and a dual stack address selection technique that works by including a multiplicity of IP addresses and ports in both the request and response messages of a connectivity establishment transaction. The IP addresses and ports provided by each side are paired and tested by peer-to-peer connectivity checks until one of these pair is selected to transport data. ICE follows the end to end principle where the clients themselves discovers, test and choose the network path to use. It makes no assumptions regarding network topology on the local or remote side. >>> >>> ICE was originally defined for the Offer-Answer (RFC 3264) protocol used by SIP (RFC 3261). Later XMPP (XEP-0176), RTSP (draft-ietf-mmusic-rtsp-nat), RTCWeb (draft-ietf-rtcweb-jsep) and other realtime media establishment protocol have used the protocol. ICE is also used by non-realtime media protocols, like HIP (RFC 5770) and RELOAD (RFC 6940). >>> >>> The goal of the ICE Working Group is to consolidate the various initiatives to update ICE to make it more suitable for the WebRTC environment but also to all the current usages of ICE. Current work in this area includes an updated version of the ICE RFC (ICEbis), Trickle ICE and dualstack/multihomed fairness. It is worth noticing that this work will make ICE more flexible, robust and more suitable for changing mobile environments without major changes to the original ICE RFC. The ICE workgroup will consider new workitems that follow this pattern. >>> >>> ICE is an application controlled protocol that leverages a set of network defined protocols. The STUN (RFC 5389), TURN (RFC 5766) and related protocol work done in the TRAM working group must be closely synchronized with the work in this working group. To avoid interoperability issues and unwanted behavior it is desired to increase the interaction with other working groups dealing with network protocols closer to the wire. Example of such work may be, but not limited to; issues regarding multi-homing, multi subnet and prefixes, QoS, transport selection and congestion control. From the application side, the users of ICE, there is a need to make sure what is specified is actually usable. Getting input from the application working groups will be helpful (RTCWEB, HIP, MMUSIC, P2PSIP). >>> >>> >>> >>> Milestones >>> >>> - Jan 2016 Submit Dual-stack Fairness with ICE as Proposed Standard >>> draft-ietf-mmusic-ice-dualstack-fairness >>> - Apr 2016 Submit a revision of ICE (RFC 5245) as Proposed Standard >>> draft-ietf-mmusic-rfc5245bis >>> (draft-ietf-mmusic-ice-sip-sdp remains in MMUSIC) >>> - Jan 2016 Submit Trickle ICE as Proposed Standard >>> draft-ietf-mmusic-trickle-ice >>> (draft-ietf-mmusic-trickle-ice-sip remains in MMUSIC) >>> >>> ————— STOP ——————— >>> >>> .-. >>> Pål-Erik >>> _______________________________________________ >>> Ice mailing list >>> Ice@ietf.org >>> https://www.ietf.org/mailman/listinfo/ice > > _______________________________________________ > Ice mailing list > Ice@ietf.org > https://www.ietf.org/mailman/listinfo/ice >
