The IESG has approved the following document: - 'Realm-Based Redirection In Diameter' (draft-ietf-dime-realm-based-redirect-13.txt) as Proposed Standard This document is the product of the Diameter Maintenance and Extensions Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-dime-realm-based-redirect/ Technical Summary The Diameter protocol allows a Diameter redirect agent to return to the message sender one or more individual hosts as destinations of the redirected message. However, in some circumstances an operator may wish to redirect messages to an alternate domain without specifying individual hosts. This document specifies a mechanism by which this can be achieved. New applications may incorporate this capability by reference to the present document. This memo updates Sections 6.13 and 6.14 of RFC6733 with respect to the usage of the Redirect-Host-Usage and Redirect-Max-Cache-Time AVPs. Working Group Summary The working group reached a consensus on the document. There are existing Service requirements for such a mechanism and the document is the result of the discussion between Diameter experts. The document has been reviewed several times, with no major issues raised as soon as the document was stable. Document Quality The proposed mechanism is a slight modification of the existing mechanism defined in the Diameter base protocol (RFC 6733). The technical content of this document relies then tightly to the existing standard specification. The problem statement has been discussed between experts inside a design team discussing Diameter enhancements and the resulting document is aligned with the output of this discussion. Several reviews of the document have been performed and the last version captures the technical agreement reached inside the Dime WG. Personnel Lionel MORAND is the document shepherd. The responsible area director is Benoit Claise. The IANA Expert(s) for the registries in this document are Lionel Morand (primary) and Jouni Korhonen (secondary).
