Azure 网络往返延迟统计信息

本文提供 Azure 区域之间的往返延迟统计信息，以帮助优化云体系结构和部署决策。 数据来自 Azure 全球基础结构的持续网络监视，并表示实际性能度量。

使用这些统计信息可以：

  • 规划多区域部署 以实现最佳性能
  • 选择 最大程度地减少用户延迟的区域
  • 设计具有 延迟注意事项的灾难恢复策略
  • 特定区域对之间的基准预期性能

什么是往返延迟？

往返延迟是指数据包从网络中的一个点到另一个点又一次传输所需的时间。 在 Azure 的上下文中，它测量数据包在两个 Azure 区域之间传输所需的时间。 此指标对于需要低延迟通信的应用程序至关重要，例如实时数据处理、游戏和金融交易。

如何测量延迟？

Azure 使用持续监视 Azure 主干网络性能的内部网络探测来测量往返延迟。 这些探测在 Azure 区域之间发送数据包，并记录数据包到达目的地和返回所花费的时间。 测量以 1 分钟间隔收集，提供随时间推移的网络性能的详细视图。

本文中提供的延迟统计信息基于这些度量的第 50 百分位数（P50），表示往返时间的中值。 这意味着，测量往返时间的一半低于此值，提供典型网络性能的可靠指标。

按区域排序的往返延迟数据

30 天时段内 Azure 区域之间的月度百分位 P50 往返时间如下选项卡所示。 延迟以毫秒 (ms) 为单位。

当前数据集于 2025 年 6 月 30 日拍摄，涵盖 2025 年 6 月 29 日结束的 30 天时间段。

为了便于阅读，每个表都拆分为 Azure 区域组的选项卡。 选项卡首先按区域分组，然后按每个表的第一列中的源区域分组。 例如，“美国东部”选项卡还显示从所有源区域到“美国东部”两个区域的延迟：“美国东部”和“美国东部 2”。

重要说明

跨 Azure 区域的每月延迟数字不会定期更改。 预计每 6 到 9 个月更新一次这些表。 下表中未列出所有公共 Azure 区域。 当新区域联机时，我们会在提供延迟数据后立即更新本文档。

可以使用 Azure 订阅中的测试虚拟机在区域之间执行 VM 到 VM 延迟。
