      Specification of the Controlled-Load Network Element Service


Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This memo specifies the network element behavior required to deliver
   Controlled-Load service in the Internet.  Controlled-load service
   provides the client data flow with a quality of service closely
   approximating the QoS that same flow would receive from an unloaded
   network element, but uses capacity (admission) control to assure that
   this service is received even when the network element is overloaded.

1. Introduction

   This document defines the requirements for network elements that
   support the Controlled-Load service.  This memo is one of a series of
   documents that specify the network element behavior required to
   support various qualities of service in IP internetworks.  Services
   described in these documents are useful both in the global Internet
   and private IP networks.

   This document is based on the service specification template given in
   [1]. Please refer to that document for definitions and additional
   information about the specification of qualities of service within
   the IP protocol family.
