This paper describes FAST TCP, a new TCP congestion control algorithm for high-speed long-latency networks, from design to implementation. The paper highlights the approach taken by FAST TCP to address the four difficulties, at both packet and flow levels, which the current TCP implementation has at large windows. It also describes the architecture and characterizes the equilibrium and stability properties of FAST TCP. The paper presents experimental results comparing the first Linux prototype with TCP Reno, HSTCP, and STCP in terms of throughput, fairness, stability, and responsiveness. FAST TCP aims to rapidly stabilize high-speed long-latency networks into steady, efficient and fair operating points, in dynamic sharing environments, and the preliminary results are promising.
