Re: [Sigtran] [M3UA] DAUD message RC

Hi Barry
	Thanks for ur reply. I should have been more specific in my first
mail. In the RC mandatory case(where multiple RKs and RCs are coordinated),
in DAUD message which RC should be sent 1) or 2) below. 

1) list of RCs corresponding(to identify the traffic flow of) to the
Destinations being Audited
2) RC of the Destination that is sending the DAUD message

Santhana,

It depends.

This is why the Routing Context parameter is classified as "Conditional" for
all of the Signalling Network Management
(SSNM) Messages. There are several cases, the first two of which are
enumerated in the description of the Routing
Context parameter, at the top of page 38 of the RFC:

A. Where a Routing Key has not been coordinated between the SGP and ASP,
sending of Routing Context is not required.

B. Where multiple Routing Keys and Routing Contexts are used across a common
association, the Routing Context(s) MUST be
sent to identify the concerned traffic flows for which the DUNA message
applies, ...

There is a third case, which is related to case A:
C. Where exactly one Routing Key has been configured for a given
association, sending of Routing Context is not required
on that association.

Case C is documented in Section 4.3.4.3. "ASP Active Procedures":
<snip>
In the case where an ASP Active message does not contain a Routing
Context parameter, the receiver must know, via configuration data,
which Application Server(s) the ASP is a member.

Hi all
            The RFC4666 says that DAUD message format is same as DUNA mesg.
Now when an ASP send DAUD message to SGP
about some Destinations, does it need to include all the associated RCs of
the Destinations which it is Auditing ?
