ECN作为TCP拥塞控制的一种决定性手段，已经被提出了很多年。然而，它在互联网上的部署比预期的要慢得多。在本文中，我们从不同的角度调查的ECN（显式拥塞通知）在互联网上的部署状态。我们使用Alexa发布的Web域名数据集作为待测试的主机。我们与每个主机协商一个支持ECN和一个不支持ECN的连接，并收集属于该连接的所有数据包。通过分析TCP/IP数据包的报头字段，我们挖掘出部署率，连通性，往返时间的变化和生存时间之间的非ECN能力和ECN能力的连接，以及IPv6能力的Web服务器的比率。特别是，很明显，连接性与域（互联网上的区域）不同。我们希望从这项研究中获得的发现将激励ISP和管理员在其网络系统中启用ECN。
ECN, as a decisive approach for TCP congestion control, has been proposed for many years. However, its deployment on the Internet is much slower than expected. In this paper, we investigate the state of the deployment of ECN (Explicit Congestion Notification) on the Internet from a different viewpoint. We use the data set of web domains published by Alexa as the hosts to be tested. We negotiate an ECN-Capable and a Not ECN-Capable connections with each host and collect all packets belonging to the connections. By analyzing the header fields of the TCP/IP packets, we dig out the deployment rate, connectivity, variation of round-trip time and time to live between the Not ECN-Capable and ECN-Capable connections as well as the rate of IPv6-Capable web servers. Especially, it is clear that the connectivity is different from the domains (regions on the Internet). We hope that the findings acquired from this study would incentivize ISPs and administrators to enable ECN in their network systems.
