各种新的传输协议已被提出的目的是有效地利用丰富的资源，在快速的长距离网络，和一些实验，以调查这些协议的性能已经被报道。然而，它们主要集中在单个连接或稳定条件下的吞吐量特性上，因此，应该针对实际使用来研究实际网络环境中的更多种类的吞吐量特性。因此，在本文中，一些实用的高速传输协议，高速TCP（HSTCP），可扩展的TCP，和简单的可用带宽利用率库（SABUL）与多个连接或竞争流量的变化的吞吐量特性进行了研究，通过实验的日本千兆网络（JGN），在日本的一个开放的测试平台，使用实现提供给公众。对于基于TCP的协议，接收端操作系统（TCP实现）的吞吐量性能的影响也进行了研究，这是从部署的角度来看，具有实际意义。在这些实验结果的基础上，给出了对快速长距离网络传输协议的一些考虑。
Various new transport protocols have been proposed with the aim of the efficient use of abundant resources in fast long-distance networks, and a number of experiments to investigate the performances of those protocols have already been reported. However, they have mainly focused on the throughput characteristics of a single connection or under a stable condition, and thus, more variety of throughput characteristics in actual network environments should be investigated aiming at practical use. Therefore, in this paper, the throughput characteristics of some practical high-speed transport protocols, high-speed TCP (HSTCP), scalable TCP, and simple available bandwidth utilization library (SABUL) with multiple connections or with changes of competitive traffic are investigated through experiments on the Japan gigabit network (JGN), an open testbed in Japan, using implementations available to the public. For TCP-based protocols, the influence of the receiver-side OS (TCP implementation) on throughput performance is also investigated, which is of practical importance from the deployment viewpoint. On the basis of the results of these experiments, some considerations on transport protocols for fast long-distance networks are given.
