Hi,

 

A couple of things:

 

First, as no additional comments were given o= n draft-kaplan-straw-b2bua-taxonomy, the chairs have now concluded to finalize the WGLC. The chairs will now take the next steps in moving= the document forward.

 

We want to give a big Thank You to everyone who prov= ided comments, and to Hadriel for addressing them and producing a new versi= on of the draft.

 

This also means that we will not discussed the do= cument in Orlando (it is on the published agenda, http://tools.ietf.org/wg/straw/agenda?item=3Dagenda-86-straw.html).<= o:p>

 

 

Second, our next delivery on the charter (http://datatra= cker.ietf.org/wg/straw/charter) is a document defining the requirements= for B2BUAs with respect to loop detection/prevention.

 

Hadriel has written a draft on the topic, http://tools.ietf.org/html/draft-kaplan-straw-b2bua-loop-detection-01, = so we encourage people to take a look. Hadriel is also going to present it in Orlando.

 

If anyone else is planning to submit a draft for the= delivery, we ask him/her to indicate that asap, because the intention is to adopt a document as base of the work soon.<= /o:p>

 

Thanks!

 

Regards,

 

Christer & Victor

I don't understand. draft-kaplan-straw-b2bua-loop-detection essentially means that a B2BUA should act as a proxy wrt Max-Forwards. If Max-Forwards is being used to target a box along the signaling path for purpose doing loopback testing, then the zero value should mean this is the endpoint for the loopback test. If the intent had been to reach the next hop beyond the B2BUA then the initial Max-Forwards value should have been one greater.

By default the receiver (proxy/B2BUA/whatever) would reject the request with a 483(Too Many Hops) error response. This looks would need a new I-D specifying those semantics. Not really. A proxy is permitted to respond to an OPTIONS when Max-Forwards is zero. That is intended to provide a traceroute like capability. And it sets a precedent. In *this* case the B2BUA, because it is a UA, can process a request with Max-Forwards of zero. (The additional semantics are really when it decides to forward the request with a decreased max-forwards.)

I guess you have a different architecture for the box in mind than I do. I was thinking that if the box normally acts as a media relay, then it probably does so as part of *its* server transaction. But of course there are an infinite number of ways to decompose the functions. > I don't have an opinion on the topic. > > If Max-Forwards was 1, the B2BUA would not pull in its media server unless caused by something else. > > If the B2BUA doesn't answer calls from a media perspective (i.e. it instead sends INVITE to media server to play treatments, auto attendant, et cetera), that means such a B2BUA will not "support end-to-end and hop-by-hop media-loopback test calls" through the use of Max-Forwards. Yeah, if it doesn't do media then it presumably doesn't do media loopback.

I= f an individual draft isn't desired to specify the new preferred behavior, = one option is to update draft-kaplan-straw-b2bua-loop-detection to 1) defin= e an option-tag to indicated the preferred behavior or 2) indicate the pref= erred behavior when SDP contains RFC 6849's loopback attribute. RFC 3261 section 8.1.1.6: "The Max-Forwards header field serves to limit the number of hops a request can transit on the way to its destination. It consists of an integer that is decremented by one at each hop. If the Max-Forwards value reaches 0 before the request reaches its destination, it will be rejected with a 483(Too Many Hops) error response." RFC 3261 section 16.3: "If the request contains a Max-Forwards header field with a field value of zero (0), the element MUST NOT forward the request. If the request was for OPTIONS, the element MAY act as the final recipient and respond per Section 11. Otherwise, the element MUST return a 483 (Too many hops) response." Draft-kaplan-straw-b2bua-loop-detection-01 section 5: "Being a UAS, B2BUAs MUST also check the received Max-Forwards header field and reject or respond to the request if the value is zero, as defined in [RFC3261]."

The B2BUAs I've seen send a 483 if they aren't final target of the INVITE. How does a proxy know to send a 200 response to an OPTIONS rather than an error when Max-Forwards is zero? Because it is one of the valid behaviors. In the current case, presumably the fact that the request is for media loopback. That isn't the normal sort of request. Presumably someone sending it knows what they are doing, including paying attention to Max-Forwards.

Hi,

 

Due to the IETF meeting, people who had provided WGL= C comments were given some extra time in order to verify that their comment= s had been addressed.

 

Mary has indicated that her comments have been addre= ssed (a couple of minor editorial fixes will still be done).

 

We will do the PROTO write-up very soon, and we will= assume that those that do not speak up DO feel that their comments have be= en addressed.

 

Thanks!
