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
