Technical Summary

   The Diameter base protocol specifies mechanisms whereby a given realm
   may advertise Diameter nodes and the supported transport protocol.
   However, these mechanisms do not reveal the Diameter applications
   that each node supports.  A peer outside the realm would have to
   perform a Diameter capability exchange with every node until it
   discovers one that supports the required application.  This document
   updates [RFC3588] and describes an improvement using an extended
   format for the Straightforward-NAPTR (S-NAPTR) Application Service
   Tag that allows for discovery of the supported applications without
   doing Diameter capability exchange beforehand.

Working Group Summary

   Since the WG consists of a few individuals, it is difficult to assess how
   solid is the WG consensus. However, the document was taken as WG item 
   with a strong consensus on its usefulness, and received good contributions 
   afterwards.

Document Quality

   There is currently no publicly announced implementations of this 
   mechanism, but there is known on-going implementation effort.
   S-NAPTR and Diameter are implemented protocols.
