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

  1. Log on to the Global Accelerator console.
  2. On the Instances page, click Purchase Basic Bandwidth Plan.
  3. On the buy 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.

    The following types of basic bandwidth plans are supported: basic, enhanced, and premium.

    Peak Bandwidth Select the bandwidth limit of the basic bandwidth plan.
    Duration Select a subscription duration of the basic bandwidth plan.

Associate a basic bandwidth plan

After you purchase a basic bandwidth plan, you must associate the bandwidth plan with a Global Accelerator (GA) instance. You can allocate bandwidth to an acceleration region only after you associate the basic bandwidth plan with a GA instance.

Each GA instance can be associated only with one basic bandwidth plan.

Make sure that a GA instance and a basic bandwidth plan are purchased before you associate the basic bandwidth plan with a GA instance. For more information, see Create and manage GA instances and Purchase a basic bandwidth plan.

  1. Log on to the Global Accelerator console.
  2. On the Instances page, find the GA instance that you want to manage and click its ID.
  3. On the page that appears, click the Bandwidth Manage tab.
  4. In the Basic Bandwidth Plan section, find the basic bandwidth plan that you want to manage and click Bind in the Actions column.
    After the basic bandwidth plan is associated with the GA instance, the basic bandwidth plan changes to the In Use state.

Replace a basic bandwidth plan

You can replace a basic bandwidth plan that is associated with a GA instance. This allows you to use the 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 the required bandwidth plan, the original one is disassociated from the GA instance and the required one is associated with the GA instance.

Make sure that the required basic bandwidth plan is purchased. The bandwidth provided by the basic bandwidth plan is equal to or more than the total bandwidth that is allocated to the specified acceleration area. For more information, see Purchase a basic bandwidth plan.

  1. Log on to the Global Accelerator console.
  2. On the Instances page, find the GA instance that you want to manage and click its ID.
  3. On the page that appears, click the Bandwidth Manage tab.
  4. In the Basic Bandwidth Plan section, find the basic bandwidth plan that you want to replace and click Replace in the Actions column.
  5. 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 Active 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 the basic bandwidth plan. Before you disassociate the basic bandwidth plan, delete all the acceleration areas and listeners that are configured. For more information, see Delete an acceleration area and Delete a listener.

  1. Log on to the Global Accelerator console.
  2. On the Instances page, find the GA instance that you want to manage and click its ID.
  3. On the page that appears, click the Bandwidth Manage tab.
  4. In the Basic Bandwidth Package section, find the bandwidth plan, and click Unbind in the Actions column.
  5. In the Unbind Bandwidth Plan message, click OK.

Change specifications

You can modify the bandwidth limit of a basic bandwidth plan. The modification immediately takes effect.

Before you change the specification of a basic bandwidth plan, take note of the following information:
  • You can only upgrade a basic bandwidth plan. To downgrade a basic bandwidth plan, make sure that your account is included in the whitelist. To enable this feature, submit a ticket.
  • To downgrade a basic bandwidth plan, make sure that the total allocated bandwidth across all acceleration regions is no more than the bandwidth limit of the downgraded plan.
  • When you upgrade or downgrade a basic bandwidth plan, make sure that the bandwidth limit of the upgraded or downgraded basic bandwidth plan does not exceed the bandwidth limit 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. On the Instances page, find the GA instance that you want to manage and click its ID.
  3. On the page that appears, click the Bandwidth Manage tab.
  4. In the Basic Bandwidth Plan section, find the basic bandwidth plan that you want to manage and click Change Configurations in the Bandwidth Limit column.
  5. On the Upgrade/Downgrade page, change the bandwidth limit of the basic bandwidth plan, select global accelerator bandwidth package Terms of Service, and then click Buy Now to complete the payment.
    Note You can only change the bandwidth type of a basic bandwidth plan from basic to enhanced. You cannot change the enhanced bandwidth type and premium bandwidth type to other bandwidth types.
