Add and manage acceleration areas

Background information

If you specify Elastic IP Address (EIP) as the type of accelerated IP address, you must specify an acceleration area for a GA instance. If you specify Anycast EIP as the type of accelerated IP address, you do not need to specify an acceleration area for a GA instance. For more information about the types of accelerated IP addresses, see Accelerated IP address.

Prerequisites

• A GA instance is created. For more information, see Create and manage GA instances.
• A basic bandwidth plan is purchased and associated with the GA instance. For more information, see Purchase and manage basic bandwidth plans.

Add an acceleration area

Add an acceleration area for a standard GA instance

1. Log on to the Global Accelerator console.
2. On the Instances page, find the GA instance that you want to manage and click the instance ID.
3. On the instance details page, click the Acceleration Areas tab, select the area that requires acceleration, and then click Add Region.
4. In the Add Acceleration Area dialog box, specify the following acceleration area information and click OK.

   Parameter	Description
   Regions	Select the region that requires acceleration. For more information about acceleration areas and acceleration regions, see Acceleration areas and regions.
   Bandwidth	Allocate bandwidth to the region. Unit: Mbit/s. Note You must allocate at least 2 Mbit/s of bandwidth to each acceleration region. The sum of bandwidth for all regions cannot exceed the bandwidth limit of the basic bandwidth plan that is associated with the GA instance. For example, if the bandwidth limit of your basic bandwidth plan is 10 Mbit/s and you allocated 6 Mbit/s to the China (Qingdao) region, the available bandwidth that you can allocate is 4 Mbit/s. If you associate a pay-as-you-go basic bandwidth plan with a GA instance, you do not need to specify the bandwidth. By default, the bandwidth allocated to each acceleration region is the same as the bandwidth limit of the pay-as-you-go basic bandwidth plan.
   Internet Protocol	Select the Internet protocol that is used to connect to GA. IPv4: assigns an accelerated IPv4 address. The accelerated IPv4 address is used to accelerate IPv4 services for IPv4 clients. IPv6: assigns an accelerated IPv6 address. The accelerated IPv6 address is used to accelerate IPv4 services for IPv6 clients. Note Only IPv6 clients in the following regions can connect to GA: China (Qingdao), China (Beijing), China (Hangzhou), China (Shanghai), China (Shenzhen), China (Heyuan), China (Guangzhou), China (Chengdu), China (Hong Kong), Singapore (Singapore), US (Virginia), and Germany (Frankfurt). In the same acceleration region of a GA instance, you can select one of the following IP address protocols: IPv4 or IPv6.

   You can click Add to add more regions and allocate bandwidth.

   Note The number of regions that can be added varies based on the specification of the GA instance. For more information about the number of acceleration regions supported by each specification , see Overview.

Add an acceleration area for a basic GA instance

You can add only one acceleration region for each basic GA instance and only accelerated IPv4 addresses are supported. By default, the bandwidth that is allocated to the acceleration region is the same as the bandwidth limit of the basic bandwidth plan that is associated with the basic GA instance.

1. Log on to the Global Accelerator console.
2. In the left-side navigation pane, click Basic Instance.
3. On the Instances page, find the GA instance that you want to manage and click the instance ID.
4. On the instance details page, click the Acceleration Areas tab, select the area that requires acceleration, and then click Add Region.
5. In the Add Acceleration Area dialog box, specify the following acceleration area information and click OK.

   Parameter	Description
   Regions	Select the region that requires acceleration. For more information about acceleration areas and acceleration regions, see Acceleration areas and regions.
   Bandwidth	By default, the bandwidth that is allocated to the acceleration region is the same as the bandwidth limit of the basic bandwidth plan that is associated with the basic GA instance. Unit: Mbit/s.
   Internet Protocol	Select the Internet protocol that is used to connect to GA. Only IPv4 is supported.

Modify an acceleration area

You can modify the bandwidth of an acceleration area for a standard GA instance. You cannot modify the bandwidth of an acceleration area for a basic GA instance. By default, the bandwidth of the acceleration region is the same as the bandwidth limit of the associated 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 the instance ID.
3. On the Acceleration Areas tab, click the tab of the acceleration area that you want to manage and click Edit Bandwidth.
4. In the Edit Acceleration Area dialog box, modify the bandwidth value and click OK.

Delete an acceleration area

You can delete an acceleration area. After the acceleration area is deleted, GA no longer provides acceleration services for this area.

Delete an acceleration area of a standard GA instance

1. Log on to the Global Accelerator console.
2. On the Instances page, find the GA instance that you want to manage and click the instance ID.
3. On the Acceleration Areas tab, find the acceleration area that you want to delete and click Delete in the Actions column.
4. In the Delete IP Addresses message, click OK.

Delete an acceleration area of a basic GA instance

1. Log on to the Global Accelerator console.
2. In the left-side navigation pane, click Basic Instance.
3. On the Instances page, find the GA instance that you want to manage and click the instance ID.
4. On the Acceleration Areas tab, find the acceleration area that you want to delete and click Delete in the Actions column.
5. In the Delete IP Addresses message, click OK.
