The IESG has approved the following document: - 'Diameter S-NAPTR Usage' (draft-ietf-dime-extended-naptr-09.txt) as a Proposed Standard This document is the product of the Diameter Maintenance and Extensions Working Group. The IESG contact persons are Dan Romascanu and Ron Bonica. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-dime-extended-naptr/ 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. Personnel Sebastien Decugis is the Document Shepherd for this document. Dan Romascanu is the Responsible Area Director.'
