使用并行 TCP 连接来提高批量传输的吞吐量是高性能计算社区中的常见做法。然而，跨并行连接的数据传输的有效性、公平性和效率尚不清楚。本文考虑系统性非拥塞相关的数据包丢失对并行 TCP 传输的有效性、公平性和效率的影响。结果表明，并行连接可有效提高聚合吞吐量，并提高网络瓶颈的整体效率。在存在与拥塞相关的丢失的情况下，并行流从其他单流中窃取带宽。提出了一个简单的修改，可以减少存在拥塞时的公平问题，但保留有效性和效率。
The use of parallel TCP connections to increase throughput for bulk transfers is common practice within the high performance computing community. However, the effectiveness, fairness, and efficiency of data transfers across parallel connections is unclear. This paper considers the impact of systemic non-congestion related packet loss on the effectiveness, fairness, and efficiency of parallel TCP transmissions. The results indicate that parallel connections are effective at increasing aggregate throughput, and increase the overall efficiency of the network bottleneck. In the presence of congestion related losses, parallel flows steal bandwidth from other single stream flows. A simple modification is presented that reduces the fairness problems when congestion is present, but retains effectiveness and efficiency.
