[Dime] Limited flexibility with NAPTR queries

["Asveren, Tolga" <tasveren at sonusnet.com>]

Something, which is bothering me recently is the limited flexibility when using NAPTR service fields to locate Diameter servers. The current values placed in the registry allow to find *a* Diameter server in a given domain. It doesn't help much if one is looking for a server for a specific application in a given domain. This could work in environments where each domain (or better said each domain which envisions use of DNS to locate its servers) has a relay/redirect as the main contact point.


My initial thoughts are:
a) We can have registry entries for each Diameter application (could be hard to manage ?)
b) We can explain in the bis document that NAPTR query should resolve to a relay/redirect for the domain, if the domain supports more than one Diameter application.

Or am I missing something?

   Thanks,
   Tolga
