Azure 網路來回行程延遲統計資料

本文提供 Azure 區域之間的來回延遲統計數據，以協助您優化雲端架構和部署決策。 資料來自 Azure 全球基礎結構的持續網路監視，並且代表真實世界的效能測量。

使用這些統計資料來：

• 規劃多區域部署 以獲得最佳效能
• 選擇 能夠為您的用戶將延遲降至最低的區域
• 基於延遲考慮設計災害復原策略
• 評估特定區域配對之間的預期效能

什麼是來回延遲？

來回延遲是數據封包從網路某個點到另一個點再返回所花費的時間。 在 Azure 的內容中，它會測量封包在兩個 Azure 區域之間移動所花費的時間。 此計量對於需要低延遲通訊的應用程式至關重要，例如即時數據處理、遊戲和金融交易。

如何測量延遲？

Azure 會使用持續監視 Azure 骨幹網路效能的內部網路探查來測量來回延遲。 這些探查會在 Azure 區域之間傳送數據封包，並記錄封包前往目的地和返回所花費的時間。 測量會以 1 分鐘間隔收集，提供一段時間網路效能的詳細檢視。

本文中顯示的延遲統計數據是以這些度量的第 50 個百分位數 （P50） 為基礎，代表往返時間的中位數。 這表示測量往返時間的一半低於此值，提供一般網路效能的可靠指標。

依區域往返延遲資料

以下分頁顯示 Azure 區域間 30 天窗口內每月 P50 往返時間百分位數。 延遲值以毫秒（ms）為單位。

目前的資料集資料自 2026年7月30 日開始，涵蓋截至 2026年7月30日的30天期間。

為了方便閱讀，分頁會將每個表格劃分為 Azure 區域的群組。 分頁會依區域組織資料，然後在每個表格的第一欄依來源區域排列。 例如，美國東部索引標籤也會顯示從所有來源區域到兩個美國東部區域的延遲：美國東部和美國東部 2。

每個延遲值都是方向性的。 不同區域之間的延遲可能與反向延遲不同，因為流量可能走不同的網路路徑。 比較區域時，使用與流量流向相符的數值。

如何閱讀延遲表

每個表格第一欄列出 來源 區域，頂列則列出 每個目標 區域。 若要查找延遲值，請先找到來源區域所在的列，然後沿著該列讀到目的區域所在的欄。 此值是以毫秒為單位的 P50（第 50 百分位數，或中位數）往返時間。

例如，在 美國東 部分頁中，來源 美國東部 的列與目的地 東美國2 的欄位顯示延遲為8毫秒。 由於延遲具有方向性，反向路徑使用不同的數值：來源 東美國2 的列與目的 東美國 的列顯示9毫秒。 一定要使用與流量流向相符的數值。

若要測量您自己的工作負載之間的延遲，而不是區域之間的延遲，請參閱 Test VM network latency，以在您的 Azure 訂閱中執行 VM 對 VM 的延遲測試。
