A burst-level adaptive input-rate flow control scheme for ATM networks

Abstract

An input rate flow control mechanism, the burst level feedback scheme, is introduced and studied. Burst level information is used to gain performance improvement. An analytical methodology, based on queuing models, is presented for the analysis and performance evaluation of this scheme. Performance results are shown to illustrate the features of the analytical technique and to demonstrate the performance improvement obtained by the scheme. This input rate control method is shown to be effective for traffic regulation at the access to an asynchronous transfer mode (ATM) network loaded by highly bursty stations. The analytical tools developed allow the system designer to evaluate the proper level of input regulation that should be used to guarantee acceptable queue-size and delay levels at the source station's buffer and at the buffer of the shared network switch.<>
