A basic bandwidth plan provides bandwidth for data transfer over the Internet and within Alibaba Cloud. This topic describes how to purchase and manage basic bandwidth plans.

Purchase a basic bandwidth plan

You can purchase subscription or pay-as-you-go basic bandwidth plans based on your business requirements. For more information about the billing rules, see Subscription bandwidth plans and Pay-as-you-go bandwidth plans. By default, you cannot use pay-as-you-go basic bandwidth plans. If you want to use these bandwidth plans, submit a ticket.

  1. Log on to the Global Accelerator console.
  2. In the left-side navigation pane, click Bandwidth.
  3. On the Bandwidth page, click Purchase Basic Bandwidth Plan.
  4. On the Global Accelerator_Basic Bandwidth Plan (Subscription) page, configure the basic bandwidth plan based on the following information, click Buy Now, and then complete the payment.
    Parameter Description
    Bandwidth Type Select a bandwidth type for the basic bandwidth plan.

    Valid values: Basic, Enhanced, and Premium.

    Peak Bandwidth Specify a maximum bandwidth value. Unit: Mbit/s.
    Duration Select a subscription duration for the basic bandwidth plan.

    You can select Auto-renewal to enable auto-renewal for the basic bandwidth plan.

  5. If you have acquired the permissions to use pay-as-you-go basic bandwidth plans, select a type of basic bandwidth plan based on your business requirements from the Purchase Basic Bandwidth Plan drop-down list on the Bandwidth page.
    • Click Purchase Basic Bandwidth Plan (Subscription). On the Global Accelerator_Basic Bandwidth Plan (Subscription) page, configure the basic bandwidth plan, click Buy Now, and then complete the payment.

      For more information, see Step 4.

    • Click Purchase Basic Bandwidth Plan (Pay-As-You-Go). On the Global Accelerator_Basic Bandwidth Plan (Pay-As-You-Go) page, set the following parameters, click Buy Now, and then complete the payment.
      Parameter Description
      Bandwidth Type Select a bandwidth type for the basic bandwidth plan.

      You can select only Premium.

      Billing Method Select a metering method for the basic bandwidth plan.

      You can select only Pay By Data Transfer.

      Bandwidth Specification Select a bandwidth specification for the basic bandwidth plan.
      Valid values: 20 Mbit/s, 50 Mbit/s, 100 Mbit/s, 200 Mbit/s, 500 Mbit/s, and 1000 Mbit/s.
      Note By default, you can select only 20 Mbit/s for pay-as-you-go basic bandwidth plans. If you want to select other specifications,submit a ticket.

Associate a basic bandwidth plan

After you purchase a basic bandwidth plan, you must associate the bandwidth plan with a Global Accelerator (GA) instance. Then, you can add acceleration areas and allocate bandwidth for acceleration.
Note After you associate a pay-as-you-go basic bandwidth plan with a GA instance, you do not need to allocate bandwidth to acceleration regions. The bandwidth of each acceleration region is the same as the bandwidth of the pay-as-you-go basic bandwidth plan.

You can associate one basic bandwidth plan with each GA instance.

Before you associate a basic bandwidth plan, take note of the following items:
  • Make sure that you have created a GA instance and a basic bandwidth plan. For more information, see Create and manage GA instances and Purchase a basic bandwidth plan.
  • You can associate only subscription basic bandwidth plans that use basic or premium bandwidth with basic GA instances.
  • If a standard GA instance uses Anycast elastic IP addresses (Anycast EIPs) as accelerated IP addresses, you can associate only pay-by-data-transfer basic bandwidth plans that use premium bandwidth with the GA instance.
  1. Log on to the Global Accelerator console.
  2. In the left-side navigation pane, click Bandwidth.
  3. On the Bandwidth page, find the basic bandwidth plan that you want to manage and click Bind Instance in the Bind Instance column.
  4. In the Bind Instance dialog box, select an instance type and a GA instance, and click OK.
    After the basic bandwidth plan is associated with the GA instance, the basic bandwidth plan changes to the In Use state.

Upgrade or downgrade a basic bandwidth plan

You can modify the maximum bandwidth and bandwidth type of a subscription basic bandwidth plan, or modify the bandwidth specification of a pay-as-you-go basic bandwidth plan. The modifications take effect immediately.

Before you upgrade or downgrade a basic bandwidth plan, take note of the following information:
  • By default, you can only upgrade basic bandwidth plans. To downgrade basic bandwidth plans, submit a ticket.
  • By default, you can select only 20 Mbit/s for pay-as-you-go basic bandwidth plans. To upgrade pay-as-you-go basic bandwidth plans, submit a ticket.
  • To downgrade a subscription basic bandwidth plan, make sure that the total allocated bandwidth across all acceleration regions does not exceed the maximum bandwidth of the downgraded bandwidth plan.
  • When you upgrade or downgrade a basic bandwidth plan, make sure that the maximum bandwidth of the upgraded or downgraded basic bandwidth plan does not exceed the maximum bandwidth that is supported by the current GA instance. For more information about GA instance types, see Overview.
  1. Log on to the Global Accelerator console.
  2. In the left-side navigation pane, click Bandwidth.
  3. On the Bandwidth page, find the basic bandwidth plan that you want to manage and click Change Configurations or Downgrade in the Bandwidth Limit column.
    • Change Configurations: You can specify a higher maximum bandwidth value or change the bandwidth type from Basic to Enhanced.
    • Downgrade: You can specify a lower maximum bandwidth value or change the bandwidth type from Enhanced to Basic.
    Note You cannot change the bandwidth type of basic bandwidth plans that use premium bandwidth.
  4. On the Upgrade/Downgrade page or Downgrade page, modify the maximum bandwidth and bandwidth type of a subscription basic bandwidth plan, or modify the bandwidth specification of a pay-as-you-go basic bandwidth plan, select the Terms of Service, click Buy Now, and then complete the payment.

Replace a basic bandwidth plan

You can replace a basic bandwidth plan that is associated with a GA instance. This allows you to use a basic bandwidth plan that meets your requirements. The GA instance continues to forward network traffic when you replace the basic bandwidth plan.

After you replace the original basic bandwidth plan with another basic bandwidth plan, the original basic bandwidth plan is disassociated from the GA instance and the new basic bandwidth plan is associated with the GA instance.

Before you replace a basic bandwidth plan, make sure that another basic bandwidth plan is purchased. The bandwidth provided by the new basic bandwidth plan must be equal to or more than the total bandwidth that is allocated to acceleration areas. For more information, see Purchase a basic bandwidth plan.

  1. Log on to the Global Accelerator console.
  2. In the left-side navigation pane, click Bandwidth.
  3. On the Bandwidth page, find the basic bandwidth plan that you want to manage and click Replace in the Actions column.
  4. In the Replace Basic Bandwidth Plan dialog box, select the basic bandwidth plan that you want to use and click OK.
    You can only select a basic bandwidth plan that is in the Idle state.

Disassociate a basic bandwidth plan

You can disassociate a basic bandwidth plan from a GA instance. If your GA instance is associated with a basic bandwidth plan, you must disassociate the bandwidth plan before you can associate the GA instance with another basic bandwidth plan.

Make sure that no acceleration areas and listeners are configured for the GA instance from which you want to disassociate a basic bandwidth plan. If acceleration areas and listeners are configured, delete the acceleration areas and listeners. For more information, see Delete an acceleration area and Delete a listener.

  1. Log on to the Global Accelerator console.
  2. In the left-side navigation pane, click Bandwidth.
  3. On the Bandwidth page, find the basic bandwidth plan that you want to manage and click Unbind in the Actions column.
  4. In the Unbind Bandwidth Plan message, click OK.
