Cloud Enterprise Network (CEN) allows you to upgrade, downgrade, and renew bandwidth plans. For example, you can change the bandwidth value of a bandwidth plan or renew a bandwidth plan based on your business requirements. This topic describes how to resize or renew a bandwidth plan, and the rules for resizing or renewing a bandwidth plan.

Rules for upgrading or downgrading a bandwidth plan

After you perform an upgrade or a downgrade, the new bandwidth immediately takes effect. Take note of the following rules for upgrades and downgrades:

  • Upgrade rules
    Upgrade fee = Cost of the upgraded plan - Cost of the original plan
    • Cost of the upgraded plan = Hourly price (Monthly price of the upgraded plan/Number of calendar days in the month/24 hours) × Remaining subscription duration in hours
    • Cost of the original plan = Hourly price (Monthly price of the original plan/Number of calendar days in the month/24 hours) × Remaining subscription duration in hours

    Examples

    On May 1, Alice purchased a subscription bandwidth plan of 2 Mbit/s for three months. The bandwidth plan enables network communication between regions inside the Chinese mainland. In the following examples, one month equals 30 days. The monthly price of the bandwidth plan is USD 68. In this case, the fee for a three-month subscription is USD 204.

    One month later, Alice upgraded the bandwidth plan to 4 Mbit/s. The monthly price of a 4 Mbit/s bandwidth plan is USD 136. In this case, the upgrade fee is USD 136. The system calculates the upgrade fee based on the following formula:

    Upgrade fee = Hourly price of the upgraded plan (USD 136/30 days/24 hours) × 2 months (60 days × 24 hours) - Hourly price of the original plan (USD 68/30 days/24 hours) × 2 months (60 days × 24 hours) = USD 136.

      Note
      • After you enable auto-renewal, the auto-renewal feature takes effect the next day.
      • After auto-renewal is enabled, the system deducts fees from your account balance to pay for the order nine days before your instance expires. Make sure that you have a sufficient balance in your payment account. Auto-renewal supports coupons.
    • If you no longer want to renew a bandwidth plan, click Nonrenewal. In the Set as Nonrenewal message, click OK.
      Note After you cancel the subscription to a bandwidth plan, you will receive only one notification before the bandwidth plan expires. When the subscription duration ends, the bandwidth plan automatically expires. You can change the renewal mode of the bandwidth plan before it expires.
