Abstract :
New services have been defined to allow the Internet to address the demands of new multimedia applications. Meeting the quality of service requirements for these services involves implementing new features on routers and bandwidth management is a key aspect of this effort. In this paper we compare the use of the ABR versus the CBR service to provide bandwidth and real-time commitments to the multimedia traffic on Internet backbones over ATM. We discuss effective throughput and delay trade-offs for a traffic mix using best effort (BE) and non-BE services. We also extend the class based queueing features to trigger bandwidth re-negotiations
