==== - 在过去,中国与国际互联网连接的“国际出口带宽”(international-export bandwidth)曾经确实是一个相对薄弱环节。比如:有报道指出,中国的人均国际出口带宽曾经在可比国家中排名较靠后。 新浪科技<ref>{{cite web|title=新浪科技|url=https://tech.sina.com.cn/t/2018-09-28/doc-ihkmwytp5747341.shtml|publisher=tech.sina.com.cn|date=2018-09-28|access-date=2025-12-10}}</ref> ==== * 虽然出口带宽整体在增长,但增长速度 往往赶不上国内网民 / 内容 /访问量增长的速度。也就是说,即便总带宽增长了,因为需求量和使用量也增长得快,所以在高峰期、跨国访问、长距离数据传输时,可能仍然会出现“拥堵”、“延迟高”、“丢包” 的体验。 新浪科技<ref>{{cite web|title=新浪科技|url=https://tech.sina.com.cn/t/2018-09-28/doc-ihkmwytp5747341.shtml|publisher=tech.sina.com.cn|date=2018-09-28|access-date=2025-12-10}}</ref> * 此外,中国的国际出口带宽及海缆登陆点相对其他国际通信枢纽国家/地区(例如美国、新加坡、日本、香港等)而言,在历史上布局和资源相对少一些。也就是说,在国际通信基础设施分布和冗余性上,有相对“集中 / 突出瓶颈”的风险。 新浪科技<ref>{{cite web|title=新浪科技|url=https://tech.sina.com.cn/t/2018-09-28/doc-ihkmwytp5747341.shtml|publisher=tech.sina.com.cn|date=2018-09-28|access-date=2025-12-10}}</ref> 因此,当你在中国大陆 — 特别是在网络高峰期、大量跨国访问需求时 — 有可能确实会感觉“国际出口很挤”“连接不稳定/慢/延迟高/丢包多”。
