             Specification of Guaranteed Quality of 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 describes the network element behavior required to deliver
   a guaranteed service (guaranteed delay and bandwidth) in the
   Internet.  Guaranteed service provides firm (mathematically provable)
   bounds on end-to-end datagram queueing delays.  This service makes it
   possible to provide a service that guarantees both delay and
   bandwidth.  This specification follows the service specification
   template described in [1].

Introduction

   This document defines the requirements for network elements that
   support guaranteed 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.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119.

   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.
