[sip-overload] Sec 5 and 6 Re: WG Last Call for draft-ietf-soc-overload-control-12

Sec 5.10.2 Rejecting Requests at an overloaded server.

I agree with the concept
“It would be fair to devote the same amount
   of processing at the overloaded server to the combination of
   rejection and processing from a non-participating client as the
   overloaded server would devote to processing requests from a
   participating client.”

But how is the server to know how much it “would devote to processing 
requests from a  participating client.” Especially under the loss scheme.

It seems to me that it would make more sense to estimate
R = ratio of (processing required to reject a request) to (processing 
required to process a request)

Then for the loss algorithm, if the server would have set oc=x, it should 
reject (1+R)x % of the requests from the non participating client.

For the rate algorithm,   if the server would have set oc=x, it should 
reject anything over x/ (1+R) requests per second from the non 
participating client.

Sec 6.2
“some algorithm called "A".”

Is there any way to be sure that, when the client says “A” and the server 
says “A”, they mean the same thing?

Dear WG partecipants, 

Volker and I would like to initiate a second 2 weeks WG Last Call on 
draft-ietf-soc-overload-control-12 (" Session Initiation Protocol (SIP) 
Overload Control") 
http://tools.ietf.org/id/draft-ietf-soc-overload-control-12.txt

The first WGLC that we run ( 
http://www.ietf.org/mail-archive/web/sip-overload/current/msg00731.html )
has produced a significant amount of feedback and comments that have been 
discussed and addressed in subsequent versions

Please send your reviews, as well as expression of support regarding 
document readiness for IESG (or not) either to the *soc* mailing list (
sip-overload@ietf.org), 
or directly to the WG chairs (Murray Kucherawy and myself). 

Comments like "I've read the document and it is Ok to publish" or 
"I've read the document and it has the following issues"
are useful and would be gratefully accepted by chairs. 

The WG LC will end on Friday, February 19th. 

Thank you, 
Salvatore as an SoC co-chair.
