Re: [M3UA] DAUD message RC

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.

Subject: [Sigtran] [M3UA] DAUD message RC


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 ?
