ATM virtual private networks: alternatives and performance comparisons

Abstract

The objective of ATM virtual private networks (AVPN) is to offer to a multi-site customer a transport service, based on the ATM backbone, which allows an efficient and flexible use of the provisioned resources and can adjust to changing traffic pattern scenarios. This objective can be reached by exploiting the virtual levels typical of the ATM (VP/VC), still guaranteeing the GOS through proper traffic control functionalities.<>
