摘要

并行传输控制协议(TCP)已被用于在高带宽延迟积(BDP)网络上有效地利用带宽进行数据密集型应用。另一方面,有人认为,一个基于单一的TCP连接经过适当的修改,如HSTCP,可以模拟和捕获并行TCP的鲁棒性,并可以很好地取代它。在这项工作中,已经进行了单基于和提议的并行TCP之间的比较,以显示其性能测量的差异,如吞吐量性能和吞吐量比,以及链路共享公平性也被观察到,以显示使用提议的并行TCP对现有单基于TCP连接的影响。实验结果表明,单TCP无法克服并行TCP,特别是在异构网络中,丢包现象非常普遍。此外,所提出的并行TCP不影响TCP的公平性,这使得并行TCP被强烈推荐用于有效利用带宽的数据密集型应用。

Test-Bed Based Comparison of Single and Parallel TCP and the Impact of Parallelism on Throughput and Fairness in Heterogenous Networks
Parallel Transport Control Protocol (TCP) has been used to effectively utilize bandwidth for data intensive applications over high Bandwidth-Delay Product (BDP) networks. On the other hand, it has been argued that, a single based TCP connection with proper modification such as HSTCP can emulate and capture the robustness of parallel TCP and can well replace it. In this work a Comparison between Single-Based and the proposed parallel TCP has been conducted to show the differences in their performance measurements such as throughput performance and throughput ratio, as well as the link sharing Fairness also has been observed to show the impact of using the proposed Parallel TCP on the existing Single-Based TCP connections. The experiment results show that, single-based TCP cannot overcome Parallel TCP especially in heterogeneous networks where the packet losses are common. Furthermore, the proposed parallel TCP does not affect TCP fairness which makes parallel TCP highly recommended to effectively utilize bandwidth for data intensive applications.
