Resource management and dimensioning in ATM networks

Abstract

A general overview of resource management aspects of ATM networks is presented, and mechanisms of load control have been considered. A general framework of resource management is first addressed. Two main aspects of traffic characterization are then examined from the traffic engineering point of view: teleservice characterization and user characterization. These form the basis of the analysis that follows. In particular, a bandwidth assignment proposal is presented and evaluated by simulation. Policing issues are discussed. The advantages of the proposed assigned method over the peak bit rate allocation method is proved for two typical dimensioning cases.
