Configuring Bandwidth

Last updated: 2020-12-15 10:52:00

    After a CCN instance is created and associated with network instances, you need to configure a bandwidth limit in both associated regions to enable communications. For a monthly-subscribed CCN instance, you also need to purchase bandwidth for the regions. Please note that the monthly-subscribed CCN instance is currently in beta. To try it out, please contact sales.

    Prerequisites

    Purchasing Bandwidth (for Monthly-subscribed CCN Instances)

    If you create a monthly-subscribed CCN instance with default bandwidth, you can use a bandwidth of 10 Kbps free of charge in all regions. If you require a higher bandwidth, please purchase bandwidth in the regions to enable communications.

    1. Log in to the VPC console and click Cloud Connect Network in the left sidebar.

    2. On the CCN instance list page, click the ID/Name of the target monthly-subscribed CCN instance to enter its details page. Click the Bandwidth Management tab.

    3. On the Bandwidth Management page, click Purchase Bandwidth. Perform the following operations in the pop-up window.

      1. Select the two regions associated with the CCN instance, and configure the bandwidth limit and usage period.

        Note:

        A bandwidth up to 10,000 Mbps can be configured.

      2. Click Confirm.

    Configuring Inter-region Bandwidth Limit (for Pay-as-you-go CCN Instances Billed by Monthly 95th Percentile)

    You can configure the inter-region bandwidth limit for pay-as-you-go CCN instances to control the bandwidth costs.

    Note:

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

    1. Log in to the VPC console and click Cloud Connect Network in the left sidebar.
    2. On the CCN instance list page, click the ID/Name of the target pay-as-you-go CCN instances to enter its details page. Click the Bandwidth Management tab.
    3. Configure the bandwidth limit depending on the speed limit mode of the CCN instance:
      • Set inter-region bandwidth limit
        Click Change Bandwidth. Select Region A and Region B from the drop-down list, and set the bandwidth cap. You can also click Add to configure multiple bandwidth limit rules. After the configuration is complete, click OK.
      • Set the region outbound bandwidth limit
        Click Adjust bandwidth speed limit. In the pop-up window, select desired regions in the Add region outbound speed limit list on the left and set the bandwidth cap on the right. Click OK.
    4. (Optional) Perform the following steps to change the bandwidth limit type to meet your requirements.
      1. Click Change on the right of Speed limit mode.
      2. Select a bandwidth limit type from the drop-down list in the pop-up window.

        Note:

        Changing the bandwidth limit type 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.

        Bandwidth Limit Description
        Region bandwidth out The outbound bandwidth cap of a single region to other regions
        Inter-region bandwidth The inbound and outbound bandwidth cap between regions. Monthly-subscribed CCN instances only support inter-region bandwidth limit.
      3. Click OK.
