您将根据所选流量包计费，超出流量包的部分将按小时计费。我们强烈建议您选择符合实际业务需求的流量包。拖动选择所需的流量包大小。\ 您还可以设置公网带宽的上限，以防止额外高额费用。如果您不设置带宽上限，将使用默认值。 ## 固定带宽计费

您将按固定带宽计费。拖动选择所需的带宽上限，适用于业务稳定且流量波动较小的情况，使用无限流量。 ## 突发 95 计费

您先使用带宽，然后按月付费。如果您有基础承诺速率，需要先预付该部分费用。系统每月采样每个实例的峰值带宽，并丢弃最高 5% 的样本。剩余的最大值即为您的实际带宽使用量。 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
