摘要
在IEEE 802.11g无线局域网中,对TCP并行连接的性能进行了评估,并对总吞吐量饱和的情况进行了一定程度的研究。另一方面,QUIC (Quick UDP Internet Connections)是一种新的传输层协议,正在标准化的最后审查过程中,它在用户空间而不是内核空间上重新实现了类似于TCP的拥塞控制和重传控制。由于它是一个相对较新的协议,因此在许多环境中尚未对其性能进行评估。在本文中,我们根据并发连接节点的数量来评估在IEEE 802.11g网络上获得最高总吞吐量的条件。此外,还考虑了拥塞控制版本、CUBIC、Reno、时延和丢包率。结果证实了QUIC和TCP可以达到相同的吞吐量水平,并阐明了延迟和丢包率对无线局域网性能的影响,以及并发连接节点之间的公平性。
Performance Evaluation on Concurrent Connecting QUIC and TCP Nodes over Wireless LAN
In IEEE 802.11g wireless LAN, the performance of TCP parallel connections has been evaluated, and the condition that the total throughput is saturated has also been investigated to some extent. On the other hand, QUIC (Quick UDP Internet Connections), which is being in the final review process of standardization, is a new transport layer protocol that re-implements congestion control and retransmission control similar to TCP in the user space on UDP instead of the kernel space. Since it is a relatively new protocol, there are many environments where its performance has not been evaluated. In this paper, we evaluate the conditions in terms of the number of concurrent connecting nodes to obtain the highest total throughput on an IEEE 802.11g network. In addition, congestion control version, CUBIC, Reno, delay and packet loss ratio are taken into account. As a result, it was confirmed that QUIC and TCP can achieve the same level of throughput, and the influence of delay and packet loss ratio on the performance in the wireless LAN was clarified, as well as the fairness among concurrent connecting nodes.
