A basic bandwidth plan provides Internet bandwidth and Alibaba Cloud internal network bandwidth for Global Accelerator (GA) instances billed by the pay-by-bandwidth metering method. After purchasing a plan, associate it with a GA instance to enable acceleration.
Basic bandwidth plans do not support data transfer between the Chinese mainland and areas outside the Chinese mainland.

Bandwidth types
Basic bandwidth plans come in three types. The type determines which endpoints can be accelerated and the applicable acceleration scope.
| Bandwidth type | Acceleration target | Supported endpoints | Acceleration scope |
|---|---|---|---|
| Basic | Applications on Alibaba Cloud | Standard GA instance: public IP addresses (Alibaba Cloud), Elastic Compute Service (ECS) instances, elastic network interfaces (ENIs), Classic Load Balancer (CLB) instances (formerly SLB), Application Load Balancer (ALB) instances, Network Load Balancer (NLB) instances, Object Storage Service (OSS) buckets, vSwitches. Basic GA instance: CLB instances, secondary ENIs, ECS instances, NLB instances. | By default, both the acceleration area and the endpoint are in the Chinese mainland. |
| Enhanced | Applications on Alibaba Cloud and outside Alibaba Cloud | Standard GA instance: public IP addresses (Alibaba Cloud), ECS instances, ENIs, CLB instances, ALB instances, NLB instances, OSS buckets, vSwitches, custom IP addresses, custom domain names. Basic GA instance: N/A. | By default, both the acceleration area and the endpoint are in the Chinese mainland. |
| Premium | Applications on Alibaba Cloud and outside Alibaba Cloud | Standard GA instance: public IP addresses (Alibaba Cloud), ECS instances, ENIs, CLB instances, ALB instances, NLB instances, OSS buckets, vSwitches, custom IP addresses, custom domain names. Basic GA instance: CLB instances, secondary ENIs, ECS instances, NLB instances. | By default, both the acceleration area and the endpoint are outside the Chinese mainland. To accelerate traffic between the Chinese mainland and other areas, select China (Hong Kong) as the acceleration region. |
Only Basic and Premium bandwidth plans can be associated with Basic GA instances that use the pay-by-bandwidth billing method. For details on supported endpoint types, see Overview and Add and manage endpoint groups and endpoints for a basic GA instance.
Purchase a basic bandwidth plan
Log on to the GA console.
In the left-side navigation pane, click Bandwidth.
On the Bandwidth page, click Purchase Basic Bandwidth Plan.
On the Global Accelerator Bandwidth Plan buy page, configure the following parameters and click Buy Now.
Parameter Description Bandwidth type The bandwidth type for the plan. Valid values: Basic, Enhanced, and Premium. Peak bandwidth The maximum bandwidth for the plan. Unit: Mbit/s. Resource group The resource group to assign the plan to. The resource group must already exist in Resource Management under the current Alibaba Cloud account. For details, see Create a resource group. Duration The subscription duration. Select Auto-renewal to renew the plan automatically.
Associate a basic bandwidth plan
After purchasing a basic bandwidth plan, associate it with a GA instance. Each GA instance can be associated with one bandwidth plan at a time.
Only subscription Basic and Premium bandwidth plans can be associated with Basic GA instances.
Prerequisites
Before you begin, ensure that you have:
A GA instance with the pay-by-bandwidth billing method. For details, see Create and manage a standard GA instance.
A purchased basic bandwidth plan (see Purchase a basic bandwidth plan).
Steps
Log on to the GA console.
In the left-side navigation pane, click Bandwidth.
On the Bandwidth page, find the basic bandwidth plan and click Bind Instance in the Bind Instance column.
In the Bind Instance dialog box, configure the following parameters and click OK.
Parameter Description Instance type The type of GA instance to associate the plan with. Valid values: Standard Instance and Basic Instance. Resource group The resource group to which the GA instance belongs. Select instance The GA instance to associate the plan with.
After the plan is associated, its status changes to In Use.
Upgrade or downgrade a basic bandwidth plan
Modify the peak bandwidth or bandwidth type of a basic bandwidth plan. Changes take effect immediately.
Limits
Upgrade: The new peak bandwidth must not exceed the maximum bandwidth supported by the associated GA instance. For instance specifications, see Overview of standard GA instances.
Downgrade: The total bandwidth allocated across all acceleration regions must not exceed the new peak bandwidth after the change.
By default, you can only increase bandwidth. To enable downgrade, first apply for the Console Downgrade quota in the Quota Center console. For details, see the "Adjust quotas" section of Manage GA quotas.
Upgrade a basic bandwidth plan
Use Change Configurations to increase the peak bandwidth or change the bandwidth type from Basic to Enhanced.
Log on to the GA console.
In the left-side navigation pane, click Bandwidth.
On the Bandwidth page, find the plan and click Change Configurations in the Bandwidth Limit column.
On the Upgrade/Downgrade page, modify Peak Bandwidth and Bandwidth Type, accept the Terms of Service, and click Buy Now.
Downgrade a basic bandwidth plan
Use Downgrade to decrease the peak bandwidth or change the bandwidth type from Enhanced to Basic.
Log on to the GA console.
In the left-side navigation pane, click Bandwidth.
On the Bandwidth page, find the plan and click Downgrade in the Bandwidth Limit column.
In the Downgrade Basic Bandwidth Plan message, confirm the downgrade details and click OK.
On the Downgrade page, specify the new specifications, accept the Terms of Service, and click Buy Now.
Replace a basic bandwidth plan
Replace the bandwidth plan associated with a GA instance without interrupting traffic forwarding. After replacement, the original plan is disassociated from the GA instance and the new plan is associated with the GA instance.
Prerequisites
Before you begin, ensure that you have:
A second basic bandwidth plan in the Idle state.
The new plan's bandwidth is greater than or equal to the total bandwidth allocated to all acceleration areas.
Steps
Log on to the GA console.
In the left-side navigation pane, click Bandwidth.
On the Bandwidth page, find the plan associated with the GA instance and click Replace in the Actions column.
In the Replace Basic Bandwidth Plan dialog box, configure the following parameters and click OK.
Parameter Description Resource group The resource group of the new bandwidth plan. Bandwidth plan to use The bandwidth plan to switch to. Only plans in the Idle state are selectable.
Disassociate a basic bandwidth plan
Disassociate a basic bandwidth plan from a GA instance to free it for use with another instance.
Before disassociating, delete all acceleration areas and listeners configured on the GA instance. For deletion steps, see the "Delete an acceleration area" section of Add and manage acceleration areas and the "More operations" section of Add and manage intelligent routing listeners.
Log on to the GA console.
In the left-side navigation pane, click Bandwidth.
On the Bandwidth page, find the plan and click Unbind in the Actions column.
In the Unbind Bandwidth Plan message, click OK.
Cancel a subscription
To unsubscribe from a subscription basic bandwidth plan, make sure you meet the unsubscription requirements before proceeding. For details, see Refund policies.
