Re: [Dime] RE: Diameter base protocol messages used by DCCA

[Anders Kristensen <andersk at cisco.com>]

OK, so at least there's a way to tell which app the AAR really is for. 
In my view it's a poor solution, though, since the code maintaining peg 
counts could very well belong to a generic Diameter stack which doesn't 
necessarily know about the particulars of DCCA. It's sort of reasonable 
to expect the stack to do something on the basis of Auth-Application-Id 
but not really for DCCA specific AVPs. It makes it unnecessarily 
difficult to layer the server code.

Thanks,
Anders
