Realm-Based Redirection In Diameter
RFC 7075, “Realm-Based Redirection In Diameter”, is a Proposed Standard document published in November 2013 by T. Tsou, R. Hao, T. Taylor. It updates RFC 6733. The canonical text is published by the RFC Editor.
Abstract
The Diameter protocol includes a capability for message redirection, controlled by an application-independent "redirect agent". In some circumstances, an operator may wish to redirect messages to an alternate domain without specifying individual hosts. This document specifies an application-specific mechanism by which a Diameter server or proxy (node) can perform such a redirection when the Straightforward-Naming Authority Pointer (S-NAPTR) is not used for dynamic peer discovery. A node performing this new function is referred to as a "Realm-based Redirect Server".
This memo updates Sections 6.13 and 6.14 of RFC 6733 with respect to the usage of the Redirect-Host-Usage and Redirect-Max-Cache-Time Attribute-Value Pairs (AVPs).
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
