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

摘要

The Available Bit Rate (ABR) service has been shown to enable persistent, greedy data sources to efficiently utilize ATM network resources. However, the throughput for bursty TCP over ABR data traffic in the presence of interfering traffic may not be as good as for persistent ABR sources without interfering traffic. This paper shows that in a comparison of rate based ABR schemes (EPRCA and ERICA) and a credit based ABR scheme (QFC), QFC performance is significantly better than rate based ABR schemes for bursty data traffic with bursty interfering traffic.
