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.
