Upgrade or downgrade a Cloud Enterprise Network (CEN) bandwidth plan to adjust its bandwidth as your business requirements change. This topic describes the rules and procedure for resizing a bandwidth plan.
Rules for resizing a bandwidth plan
The following table describes the rules for resizing a bandwidth plan.
Item | Description |
Resize limits | Before you downgrade a bandwidth plan, make sure that the total bandwidth allocated to its inter-region connections does not exceed the bandwidth value to which you want to downgrade. You can adjust the bandwidth of an inter-region connection. For more information, see Modify connection bandwidth. |
Effective time | A resize operation takes effect immediately, but the change may be delayed for several minutes due to network conditions. |
Billing impact | If you upgrade a bandwidth plan, you must pay the price difference for the remaining time of the current billing cycle. If you downgrade a bandwidth plan, a refund may be generated. For more information, see Billing impact of resizing a bandwidth plan in this section. |
Scenarios | If the bandwidth of a bandwidth plan cannot meet your business requirements, upgrade the bandwidth plan. If the bandwidth exceeds your business requirements, downgrade the bandwidth plan. |
Billing impact of resizing a bandwidth plan
If you upgrade a bandwidth plan, you must pay the price difference for the remaining time of the current billing cycle. The upgrade fee is calculated based on the following formulas:
Upgrade order price = Price of the new configuration for the remaining duration - Price of the original configuration for the remaining duration
Price of the new configuration for the remaining duration = Hourly price (Monthly price of the new configuration / Total days in one month / 24 hours) × Remaining duration
Price of the original configuration for the remaining duration = Hourly price (Monthly price of the original configuration / Total days in one month / 24 hours) × Remaining duration
For more information, see Example of upgrade billing in this section.
If you downgrade a bandwidth plan, a refund may be generated. The refund is the difference between the price of the new configuration for the remaining billing cycle and the actual remaining value of the bandwidth plan before the downgrade. The actual remaining value is affected by the discounts and vouchers applied at the time of purchase. The amount displayed on the order page prevails. For more information, see Refunds for resource downgrades.
Example of upgrade billing
On May 1, you purchase a 2 Mbps bandwidth plan to connect regions in the Chinese mainland. The subscription duration is three months. To simplify the calculation, assume that one month has 30 days and that the monthly price of the bandwidth plan is USD 68. You must pay USD 204 in total.
After you use the bandwidth plan for one month, you want to upgrade the bandwidth plan to 4 Mbps. Assume that the monthly price of a 4 Mbps bandwidth plan is USD 136. You must pay an additional USD 136. The details of the upgrade order are as follows:
Upgrade order price = Hourly price (USD 136 / 30 days / 24 hours) × 2 months (60 days × 24 hours) - Hourly price (USD 68 / 30 days / 24 hours) × 2 months (60 days × 24 hours) = USD 136.
Procedure for resizing a bandwidth plan
Log on to the CEN console.
On the CEN Instance page, click the ID of the CEN instance that you want to manage.
On the details page of the CEN instance, choose . Find the bandwidth plan that you want to resize. In the Bandwidth column, click Downgrade or Upgrade.
In the Bandwidth section, adjust the bandwidth value of the bandwidth plan.
In the Terms of Service section, read and select Terms of Service, click Buy Now, and then complete the payment.
The resize takes effect immediately. Due to network conditions, the new bandwidth value may take several minutes to be displayed.
