Amazon Web Services · 2026-06-01 · via Recent Announcements

AWS Direct Connect 现已在专用连接上支持虚拟接口(VIF)速率限制器,该功能可帮助您防止因 VIF 上意外流量激增导致的网络拥塞。此类拥塞可能耗尽所有可用带宽,从而影响同一连接上其他 VIF 的工作负载。

使用 VIF 速率限制器,您可以在专用连接上为最多 10 个 VIF 设置最大带宽分配,在使用链路汇聚组时,可从 50 Mbps 到 1.6 Tbps 的广泛可用容量增量中进行选择。速率限制适用于进出 AWS 网络的流量。如果速率受限 VIF 上的流量超过配置的容量,多余的数据包将被丢弃,从而防止该 VIF 消耗同一连接上其他 VIF 所需的带宽。一项新的流量利用率指标(以 VIF 配置容量的百分比形式表示)以及丢包数将发布到 Amazon CloudWatch,在这里,您可以根据阈值配置警报。这些新指标可帮助您轻松了解 VIF 如何使用其带宽分配,并据此进行相应调整。

VIF 速率限制器已在支持 AWS Direct Connect 专用连接的所有 AWS 区域的商业和中国分区推出。您可以通过 AWS Direct Connect 控制台、API 或 SDK 配置速率限制器。

要了解更多信息,请参阅 AWS Direct Connect 用户指南中的“VIF 速率限制器”。
