Abstract

This memo captures Diffserv working group agreements concerning new

and improved terminology, and provides minor technical

clarifications. It is intended to update RFC 2474, RFC 2475 and RFC

2597. When RFCs 2474 and 2597 advance on the standards track, and

RFC 2475 is updated, it is intended that the revisions in this memo

will be incorporated, and that this memo will be obsoleted by the new

RFCs.

1. Introduction

As the Diffserv work has evolved, there have been several cases where

terminology has needed to be created or the definitions in Diffserv

standards track RFCs have needed to be refined. Some minor technical

clarifications were also found to be needed. This memo was created

to capture group agreements, rather than attempting to revise the

base RFCs and recycle them at proposed standard. It updates in part

RFC 2474, RFC 2475 and RFC 2597. RFC 2598 has been obsoleted by RFC

3246, and clarifications agreed by the group were incorporated in

that revision.

2. Terminology Related to Service Level Agreements (SLAs)

The Diffserv Architecture [2] uses the term "Service Level Agreement"
