Raw notes follow: ------------------------------ Notes on SIMPLE at IETF 70 Reported by Dean Willis Chairs, Robert Sparks, Hisham Khartabil "Note Well" presented Topic: Agenda Bash / Status by Chairs slides presented Agenda accepted as presented. Issue: Status Noted that prescaps-ext has an issue that needs to be considered by group. This is essentially a presence-able XML encoding of RFC 3840/3841 preferences and capabilities. This may have privacy implications, like revealing the kind of phone. Do we care? This probably needs to be reflected in the security considerations section of the draft. Issue: draft-ietf-simple-chat-00 MSRP-based chat solution that is future-compatible with XCON. Nicknames have been a contentious issue that is now at an impasse. Mary noted that this is a general problem and XCON needs an answer. Miguel answers that the simple-chat solution was intended to be a tightly constrained subset. Poll: Who wants this? OMA appears to still have a dependency. Several people are planning implementations. Hisham doesn't want this tied to XCON. Adam continued this explanation, reinforcing its separation from XCON. Problem restated as "how to inform the conference server of the nickname that will be exposed to other users?". So the issue is that the current draft only works for IM chat and not for XCON. Geir Arne Sandbakken has volunteered to coordinate a resolution of the problem. Poll: Can we agree to move forward with a non-general mechanism if we can't come to closure on a more general one in the next month? That is, we will adopt the existing mechanism if we don't find something better. Topic: Interdomain Scaling Analysis Led by Avshalom Houri slides presented. Slide: What Can Be Done Henning raises issues about changing the model, which conveys a lot of useless information, needs to be changed in order to impact the order of the scaling problem. Henry asks if p2p would reduce the problem? Some debate ensued on whether the problem is the total bandwidth or the central server load. Discussion: What next? Poll: Ready for WGLC? No objections were noted. Chair proposed a January WGLC. Topic: View Sharing Led by Jonathan Rosenberg slides presented Question: Interest in pursuing this? Several speakers expressed interest. Noted that there is a configured relationship between domains here. Discussion seems generally favorable. Chairs and authors will discuss and review the requirements and referring to SIP. Poll: If you will participate in talking about this draft wherever it lands, please hum . . (much support shown). Topic: AMI Extensions to PDF Led by henning Schulzrinne Slides presented Discussion: Several speakers in favor. Possible issue that list of games is inadequate. Poll: Who read interdomain draft that JDR submitted? Several: Who would review ow? A few. Chair will take proposal to list for WG finalization. Poll: Who read view-sharing draft? Many. Conclusion: Plan to take on as WG item.
