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.
