Throughput of high-speed TCP in optical burst switching networks

High-speed TCP (HSTCP) has been proposed to achieve high throughput in the high bandwidth and long-delay environment. The throughput of HSTCP is studied when the backbone network adopts the optical burst switching (OBS) technology. The study shows that small burst assembly time and a large burst loss ratio in OSB can reduce the throughput of HSTCP significantly, but HSTCP still performs much better than TCP.
