4 Capacity Admission Control

This chapter presents a taxonomy and review of the mechanisms available for capacity admission control in IP networks.

4.1 Introduction

Connection-oriented network technologies such as time division multiplexing (TDM) and asynchronous transfer mode (ATM) have an implicit admission control capability which is used in establishing the path between sender and receiver, to ensure that there are sufficient resources for the connection. In contrast, IP is connectionless, and has no implicit admission control capability.

In Chapter 3, we described how to deploy the Differentiated Services architecture (Diffserv); Diffserv is by far the most widely deployed IP QOS architecture today, in both enterprise and SP networks. Diffserv ...
