Abstract

   This specification documents an extension to the Diameter Overload
   Indication Conveyance (DOIC) 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 sent to the DOIC reporting
   node.
