アブストラクト
  Our group has been conducting a series of experiments on various recently available high-speed transport protocols over long-distance, 10-gigabit-class, international testbed networks. The study reported here focuses on the scenario of multiple coexisting flows along an end-to-end 10-Gbps path, where TCP-based transport protocols are used. The results show that two coexisting high-speed flows cannot share network resources efficiently. For example, for some protocols, competition between two flows prevents the sum of their throughputs from fully utilizing available bandwidth, especially when flows have the same RTT, and causes considerable imbalance in the time-averaged throughput between two flows, especially when there are different RTTs.
