Abstract

The guiding principles in the design of IP network management were simplicity and no centralized control. The best effort service paradigm was a result of the original management principles and the other way around. New methods to distinguish the service given to one set of packets or flows relative to another are well underway. However, as IP networks evolve the management approach of the past may not apply to the Quality of Service (QoS)-capable network envisioned by some for the future. This document examines some of the areas of impact that QoS is likely to have on management and look at some questions that remain to be addressed.

Abstract

   The guiding principles in the design of IP network management were

   simplicity and no centralized control.  The best effort service

   paradigm was a result of the original management principles and the

   other way around.  New methods to distinguish the service given to

   one set of packets or flows relative to another are well underway.

   However, as IP networks evolve the management approach of the past

   may not apply to the Quality of Service (QoS)-capable network

   envisioned by some for the future.  This document examines some of

   the areas of impact that QoS is likely to have on management and look

   at some questions that remain to be addressed.

1. Introduction

   Simplicity above all else was one of the guiding principles in the

   design of IP networks.  However, as IP networks evolve, the concept

   of service in IP is also evolving, and the strategies of the past may

   not apply to the full-service QoS-capable network envisioned by some

   for the future.  Within the IP community, their exists a good deal of

   impetus for the argument that if the promise of IP is to be

   fulfilled, networks will need to offer an increasing variety of

   services.  The definition of these new services in IP has resulted in

   a need for reassessment of the current control mechanism utilized by

   IP networks.  Efforts to provide mechanisms to distinguish the

   service given to one set of packets or flows relative to another are

   well underway, yet many of the support functions necessary to exploit

   these mechanisms are limited in scope and a complete framework is
