Otmar,

Part of this issue has been other priorities on my part.  I am guilty of not taking the time to respond to these tickets, but I do care about them.  Each of the questions make sense, and I finally responded to them.  

Why others are not, is beyond me.  So, you say the architecture is a "collection of vague statements."  Like all work within the working group, it is development by committee.  This is a "working group item."  This means, suggest wording to fix it.  There are those who talk and those who do.  Let's fix it, otherwise it will just float around until it dies (which, the defibrillator has already been used.)

I know from experience there is a lot of peering going on.  Whether SSPs call it "IP transit," "peering," "IP termination," etc.  It's happening.  People need to share there experiences, as well as help the industry move past the LERG and NPAC.  These are legacy databases, which are anchors to innovation.

Also, for some reason all of the IETF vendor representatives do not seem to want to evolve peering.  They are all happy with PSTN replacement.  Personally, this is not what I had in mind when it comes to peering.  I do not want to see us simply replicating the PSTN.  I've heard a similar statement in other SIP groups, but yet here we are.  While I agree we needed to get some basic frameworks around supporting voice in a peering scenario, the way we support voice does not have to simply replicate the PSTN.  If I said this in the past, then shame on me.  The landscape is changing, and we need to use our collective brain power to make sure it goes in the right direction.

Before I get to far down this path, there have been innovative discussions and drafts in the IETF applying to peering.  Unfotunately, due to scattered application, they have been discussed in many different forums.  Some examples include ViPR (http://tools.ietf.org/html/draft-rosenberg-dispatch-vipr-overview-02), Session ID (http://tools.ietf.org/html/draft-kaplan-sip-session-id-02), Performance metrics (http://tools.ietf.org/html/draft-ietf-pmol-sip-perf-metrics-05), "Re: [dispatch] Thoughts on SIP routing, TRIP, and ENUM (Long!) (http://www.ietf.org/mail-archive/web/dispatch/current/msg01686.html), Egress Route in ENUM (http://tools.ietf.org/html/draft-malas-dispatch-sip-egress-route-00), etc.

Peering is being dealt with in the IETF, but it's just not all addressed in the Speermint working group (which, may be fine...not the point of this rant).

Regards,

Daryl

I haven't seen any action in the trac pages since Adam posted them.

As I raised the questions documented in these tickets, I'm left to wonder whether

* the questions themselves just make no sense, or

* the group is not prepared to propose an architecture that nails down some of the decisions one faces when actually implementing a peering scheme.

As it stands, the current architecture draft is a collection of vague statements -- suitable perhaps for an executive level power-point presentation -- but of very little use to any techie who is tasked with building a real-world SSP network and its interconnections.

As I see it, speermint is stuck in power-point space.
