Simulation model. We used QualNet 4.5.1; TCP SACK with delay-ACKs, Nagale algorithm, RFC1323, and Keepalive probes; maximum segment size was 1,500 bytes; send buffer size was 65,000 bytes; receive buffer size was 65,000 bytes; wired bottlenecklink bandwidth was 10 Mbps, while other links bandwidth were 100 Mbps.
