=== 即使有防火墙,跨境访问依然是刚需,主要包括: === ===== 所有外贸企业的: ===== * 邮件 * ERP 系统 * 海外订单平台 * 亚马逊/Temu/Shopee 等电商系统 * 国际物流平台 全部需要跨境访问。 ===== 大量外企在中国设分部,必须连接: ===== * 总部 VPN * 海外服务器 * 全球数据中心 这些都是正常合法的跨境流量。 ===== 中国企业在国外的服务和数据中心非常多,例如: ===== * TikTok / 抖音国际版 * 阿里云海外节点 * 腾讯在新加坡/洛杉矶的数据中心 * 字节跳动在美欧的数据处理系统 * 游戏公司在全球的服务器 这类数据量非常大。 ===== 比如: ===== * Zoom(大量企业用) * Microsoft 365 * AWS / Azure / Google Cloud * 跨国公司内部视频会议 * 外国大学/研究机构资源访问 这些都是合法的跨境流量。 ===== 例如: ===== * App Store 程序下载 * Steam * GitHub 镜像同步 * Ubuntu/Debian 镜像同步 * 海外 CDN 的内容推送回国内 这些都会产生巨量跨境带宽。 ➡️ 所以,跨境流量大,是经济结构决定的,不会因为 GFW 存在而减少。
