Re: [Sip] Terminology (was RE: Fwd:I-DACTION:draft-rosenberg-sip-target-uri-delivery-01.txt
Hi Mary,
A couple of question:
1. Does the 4244bis definition of "retarget" cover the
freephone case, when the R-URI is replaced with the AoR of B - not with the
contact of B - no matter whether it's done based on location service,
configuration or whatever?
2. Related to the first question, when you say "...and thus
chaning the target of the request", what is the defintion of
"target"?
Regards,
Christer
When I
use "retarget" I am using the definition that I put into 4244bis. So, if
you could ignore the tag or change it to 'iscontact' or whatever, what would you
change in that definition? Also, consider that if you were to change everyplace
that I use "retarget"/"retargeted"/"retargeting" in 4244bis with 'iscontact' the
text would not make sense. So, even if we change the name of the tag, we still
need to understand the concept or define another term that means that the
request-uri in the incoming request (which should be the same as the last
hi-entry in the request) is being chnaged due to service lookup, configuration,
blah, blah, blah and that to meet the requirements in the target-uri document,
we want to tag this entry so that this request-uri is not "lost" - i.e., this is
the one the services identified in the target-uri document care about.
So,
right now, here's what's in 4244bis:
The term "retarget" is used in this
document to refer to the process
of a Proxy Server/User Agent
Client (UAC) changing a Uniform Resource
Identifier (URI) in a
request based on a lookup in a location service
and thus changing the target of the
request.
We
have previously discussed that we do need to expand the "based on a lookup in a
location service" to include configuration, etc., so let's not debate that.
But,
what explicitly is the concern with that definition?
Mary.
I'm fine with discussing implementation if everyone is meaning the
same if they use the same words.
As to the "retarget" term such
does not seem to be the case.
