Hi David, Best Regards! -Haibin
From: P2PSIP [mailto:[email protected]] On Behalf Of David Bryan Sent: Saturday, June 14, 2014 4:40 AM To: P2PSIP WG Subject: [P2PSIP] Concepts Draft I was recently asked to update the concepts draft and discuss the important issues. The pass that has been made is largely around normalizing the text to be compliant with the terminology of RFC 6940, but it certainly will need an additional pass after a few questions to the group: To move this draft forward, there are a few open issues/questions: MAJOR OPEN ISSUE: The initial wording in the high-level description about proving AoR to contact mapping reflects a very long and contentious debate about the role of the protocol, and reflected a pretense that this was an overlay only for P2PSIP. That is not really true in base anymore (see last paragraph of introduction) and the language has been very much genericized in base. Should we make this text more abstract and then use AoR->contact mapping as an example of the (original) use? On a related note, see the last paragraph of the Background section -- do we want to reword this? (my thought would be to make the text more generic, and mention that the AoR->contact mapping is the most popular usage...) [Haibin] I agree. And the last paragraph in background section needs rewording where it says DHT is just for a distributed SIP registrar. OPEN ISSUE: Should we include a section that documents previous decisions made, to preserve the historical debate and prevent past issues from being raised in the future, or simply rely on the mailing list to address these concerns? (I don't think we want to do this. Huge (and largely unneeded) can of worms, but it has been in the open issues section for some time and should be at least asked of the list) [Haibin] Is it a normal practice to document that? And for a concept draft? I do not think so. OPEN ISSUE: Should we include the use cases from draft-bryan-p2psip-app-scenarios-00 (now long expired)? There was some interest in doing so in previous versions, but no conclusion was reached. (given the current stage of the group, I would say these aren't likely to be useful anymore, but again, as it is currently listed as an open issue in the draft, need to check) [Haibin] It is usually good to have application scenarios, but with regarding to the current status of this group, it might be better to document those in a independent draft if we really need them. The final open issue is do we want to advance the draft? In discussion with the chairs and some folks, it seems the answer is yes, there is useful material and we should push the draft out, but I wanted to discuss. Assuming there is still interest, I'd also welcome any comments on the draft...I'm sure I missed a few spots where it no longer aligns with 6940. [Haibin] IMO, yes. BR, -Haibin
