跨国互联网绩效是衡量一个国家基础设施投资、全球化和开放程度的重要指标。我们对29个国家和地区的跨国互联网绩效进行了大规模的测量研究,发现六个国家的绩效令人惊讶地低。其中五个是非洲国家,最后一个是中国大陆,这是一个重要的异常值,下游和上游业绩之间存在重大差异。然后,我们对中国大陆不寻常的跨国互联网表现进行了全面的调查,我们称之为“中国的大瓶颈”。我们的研究结果表明,这种瓶颈是普遍存在的,影响了我们测量的79%的接收者-发送者对。超过70%的线对每天遭受超过5小时的极慢速度(低于1~Mbps)。在大多数测试中,瓶颈似乎位于中国境内,表明处理跨国流量的网络基础设施薄弱。这一现象对中国用户的浏览习惯以及外国互联网服务接触中国客户的能力产生了深远的影响。
Transnational Internet performance is an important indication of a country's level of infrastructure investment, globalization, and openness. We conduct a large-scale measurement study of transnational Internet performance in and out of 29 countries and regions, and find six countries that have surprisingly low performance. Five of them are African countries and the last is mainland China, a significant outlier with major discrepancies between downstream and upstream performance. We then conduct a comprehensive investigation of the unusual transnational Internet performance of mainland China, which we refer to as the "Great Bottleneck of China''. Our results show that this bottleneck is widespread, affecting 79% of the receiver--sender pairs we measured. More than 70% of the pairs suffer from extremely slow speed (less than 1~Mbps) for more than 5 hours every day. In most tests the bottleneck appeared to be located deep inside China, suggesting poor network infrastructure to handle transnational traffic. The phenomenon has far-reaching implications for Chinese users' browsing habits as well as for the ability of foreign Internet services to reach Chinese customers.
