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:

• The following rules apply to instances created after 00:00, February 24, 2020:

  Network Billing Mode	Instance		Bandwidth Cap Range (Mbps)
  	Instance Billing Mode	Instance Configuration
  Bill-by-traffic	Pay-as-you-go instances	ALL	0 - 100
  Bill-by-bandwidth	Pay-as-you-go instances	ALL	0 - 100
  Bandwidth package	All		0 - 1000

• The following rules apply to instances created before 00:00, February 24, 2020:

  Network Billing Mode	Instance		Bandwidth Cap Range (Mbps)
  	Instance Billing Mode	Instance Configuration
  Bill-by-traffic	Pay-as-you-go instances	All	0 - 100
  Bill-by-bandwidth	Pay-as-you-go instances	All	0 - 100
  Bandwidth package	All		0 - 1000

Inbound Bandwidth Cap (Upstream Bandwidth)

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

• If the fixed bandwidth purchased by users is greater than 10 Mbps, Tencent Cloud assigns a public network inbound bandwidth that is equal to the purchased bandwidth.
• If the fixed bandwidth purchased by users is less than 10 Mbps, Tencent Cloud assigns 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:

Increasing the Bandwidth Cap

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

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

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.
4. In the Adjust Network window that appears, set the target bandwidth cap and click OK, as shown in the following figure.
