Single FASP and TCP flows sharing a 10 Mbps bottleneck bandwidth (100 ms RTT). A FASP flow is started with a target rate at link capacity (9.95 Mbps) and runs steadily. After two minutes, a TCP flows starts up and stabilizes at 2.3 Mbps, TCP's self-limited rate. FASP detects the presence of TCP and immediately reduces rate to the remaining available bandwidth (7.7 Mbps) without inhibiting TCP. When FASP terminates, TCP stays roughly at the same rate.
