Configuring Bandwidth

Last updated: 2021-09-29 15:01:30

    After creating and associating a CCN instance with network instances, you need to configure bandwidth to enable communications. If the CCN billing mode is pay-as-you-go by monthly 95th percentile, configure a bandwidth cap in both regions the CCN instance connects to.


    Setting Cross-region Bandwidth Cap (for Pay-as-you-go CCN Instances Billed by Monthly 95th Percentile)

    You can configure a cross-region bandwidth cap for pay-as-you-go CCN instances billed by monthly 95th percentile to control the bandwidth costs.


    The default bandwidth cap is 1 Gbps. If you require a higher bandwidth, please submit a ticket.

    1. Log in to the CCN console and access the CCN management page.

    2. On the CCN instance list page, click the ID/Name of the target pay-as-you-go CCN instances billed by monthly 95 percentile to enter its details page. Click the Bandwidth Management tab.

    3. (Optional) Perform the following steps to change the bandwidth limit mode to meet your requirements.

      1. Click Change on the right of the Bandwidth limit mode.

      2. Select a bandwidth limit mode from the drop-down list in the pop-up window.


        Changing the bandwidth limit mode will delete existing configurations. The bandwidth cap will be set to 1 Gbps by default. If you require a higher bandwidth, please submit a ticket.
