When a Diameter server or agent becomes overloaded, it needs to be
able to gracefully reduce its load, typically by advising clients to
reduce traffic for some period of time.  Otherwise, it must continue
to expend resources parsing and responding to Diameter messages,
possibly resulting in a progressively severe overload condition.  The
existing Diameter mechanisms are not sufficient for managing overload
conditions.  This document describes the limitations of the existing
mechanisms.  Requirements for new overload management mechanisms are
also provided.

This document is a product of the Diameter Maintenance and Extensions Working Group of the IETF.
