Performance of ATM available bit rate for bursty TCP sources and interfering traffic

The Available Bit Rate (ABR) service has been shown to enable persistent, g reedy data sources to efficiently utilize ATM network resources. However, t he throughput for bursty TCP over ABR data traffic in the presence of inter fering traffic may not be as good as for persistent ABR sources without int erfering traffic. This paper shows that in a comparison of rate based ABR s chemes (EPRCA and ERICA) and a credit based ABR scheme (QFC), QFC performan ce is significantly better than rate based ABR schemes for bursty data traf fic with bursty interfering traffic.
