    Outbound Bandwidth Cap (Downstream Bandwidth)

    The public network bandwidth cap refers to the upper limit of outbound bandwidth by default, i.e. the bandwidth going out from CVM instances. The public bandwidth cap varies for different network billing mode. See below for details:

    Inbound Bandwidth Cap (Upstream Bandwidth)

    The inbound bandwidth of the public network refers to the bandwidth that flows into CVM instances.

    • If the bandwidth you purchased is greater than 10 Mbps, Tencent Cloud will assign a public network inbound bandwidth equals to the purchased bandwidth.
    • If the bandwidth you purchased is less than 10 Mbps, Tencent Cloud will assign 10-Mbps public network inbound bandwidth.

    Bandwidth Peaks

    The bandwidth peak is applicable to both bill-by-traffic and bill-by-bandwidth, but it means differently in these two cases as follows:

    Bill-by-traffic Bill-by-bandwidth (including hourly bill-by-bandwidth and monthly-subscribed bandwidth)
    The bandwidth peak is only a bandwidth cap, instead of a commitment indicator. It may be limited when there is a scramble for bandwidth resources. The bandwidth peak is a commitment indicator. It will not be limited when there is a scramble for bandwidth resources.

    Increasing the Bandwidth Cap

    You can choose one of the following adjustment methods based on your needs:

    If you cannot adjust your instance or network billing mode, submit a ticket to request to increase the bandwidth cap. We will get back to you as soon as possible.

    Adjusting the network billing mode (bill-by-bandwidth)

    1. Change the billing mode of bill-by-traffic instances to bill-by-bandwidth. For detailed operations, see Adjusting the Network Configuration.
    2. Log in to the CVM console.
    3. Locate the instance for which you want to adjust the bandwidth and choose More > Resource Adjustment > Adjust Network on the right.
    4. In the Adjust Network window that appears, set the target bandwidth cap and click OK.

    Adjusting the network billing mode (bill-by-bandwidth-package)

    1. Change the billing mode of bill-by-traffic instances to bill-by-bandwidth-package.
    2. Log in to the CVM console.
    3. Locate the instance for which you want to adjust the bandwidth and choose More > Resource Adjustment > Adjust Network on the right.
