Translation of QoS parameters into ATM performance parameters in B-ISDN

Abstract

The quality of service (QoS) concept for broadband ISDN (B-ISN) is studied. The QoS parameters in the asynchronous transfer mode (ATM) layer and the AAL (ATM adaptation layer) are defined. The focus is on the translation of QoS parameters between layers, particularly from the AAL to the ATM layer, because the AAL must be designed to be service dependent and specific. The QoS parameters at the ATM layer resulting from the translation will be the performance requirements on a connection basis for the ATM network. The impact of QoS parameter translation on guaranteeing QoS in the ATM network is discussed.<>
