Abstract

   This specification documents an extension to the Diameter Overload
   Indication Conveyance (DOIC) [RFC7683] base solution.  This extension
   adds a new overload control abatement algorithm.  This abatement
   algorithm allows for a DOIC reporting node to specify a maximum rate
   at which a DOIC reacting node sends Diameter requests to the DOIC
   reporting node.

Requirements

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
