Global Accelerator:Add and manage acceleration areas

Background information

If you specify Global Accelerator 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 Global Accelerator instance. For information about the types of accelerated IP addresses, see the "Accelerated IP addresses" section of the Overview topic.

Prerequisites

• A standard Global Accelerator instance is created. For more information, see Create and manage standard GA instances.

• If the bandwidth metering method of the Global Accelerator instance is Pay-By-Bandwidth, make sure that you purchased a basic bandwidth plan and associated it with your GA instance. For more information, see Purchase and manage basic bandwidth plans.

Add an acceleration area

1. Log on to the GA 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. Then, click Add Acceleration Area.

4. In the Add Acceleration Area dialog box, configure the parameters and click OK. The following table describes the parameters.

   Parameter	Description
   Select Acceleration Region	Select the region that requires acceleration from the drop-down list. For more information about the acceleration areas and regions, see Overview. Note The number of acceleration regions that can be added for a subscription Global Accelerator instance is determined by the maximum bandwidth of the bandwidth plan and the specifications of the GA instance. For more information about the number of acceleration regions that are supported by each instance type, see Overview of standard GA instances.
   Assign Bandwidth	Select a bandwidth allocation method. This parameter is available to Global Accelerator instances that support multiple acceleration regions. Allocate Bandwidth by Region: This method is suitable for scenarios in which you want to allocate different bandwidth to different acceleration regions. Allocate Bandwidth: This method is suitable for scenarios in which you want to allocate the same bandwidth to different acceleration regions. You need to only configure bandwidth for one acceleration region.
   Bandwidth	Specify bandwidth for the acceleration region. Unit: Mbit/s. If the bandwidth metering method of the Global Accelerator instance is pay-by-bandwidth, the sum of the bandwidth of all acceleration regions cannot exceed the maximum bandwidth of the subscription basic bandwidth plan that is associated with the GA instance. You must allocate at least 2 Mbit/s of bandwidth. If the bandwidth metering method of the Global Accelerator instance is pay-by-data-transfer, the bandwidth that you can allocate to each region ranges from 2 Mbit/s to 10,000 Mbit/s. Note For subscription Global Accelerator instances, we recommend that the sum of bandwidth for all acceleration regions does not exceed the maximum bandwidth that is supported by the Global Accelerator instance. For more information about the limits and examples of bandwidth allocation, see the "Accelerated IP addresses" section of the Overview topic.
   IP Protocol	Select the IP version that is used to connect to Global Accelerator. 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 GA supports only IPv6 clients in the following regions: China (Qingdao), China (Beijing), China (Hangzhou), China (Shanghai), China (Shenzhen), China (Heyuan), China (Guangzhou), China (Chengdu), China (Hong Kong), Singapore, US (Virginia), and Germany (Frankfurt). In the same acceleration region of a GA instance, you can select one of the following IP versions: IPv4 and IPv6. If you select IPv6 as the IP version of an acceleration region, only IPv6 clients in the region can connect to GA.
   ISP Line Type	Select an ISP line type for the Global Accelerator. This parameter is available only to Global Accelerator instances whose bandwidth metering method is pay-by-data-transfer. BGP (Multi-ISP) (default): provides high-quality BGP lines worldwide. BGP lines from different Internet service providers (ISPs) are used at the same time and the optimal BGP line is automatically selected to ensure network stability. Supported ISPs are China Telecom, China Unicom, China Mobile, China Mobile Tietong, China Netcom, CERNET, NRTA, Dr.Peng Group, and Founder Broadband. All acceleration regions support BGP (Multi-ISP). BGP Pro: BGP (Multi-ISP) Pro lines optimize data transmission to the Chinese mainland and improve connection quality for international services. Compared with BGP (Multi-ISP) lines, when BGP (Multi-ISP) Pro lines provide services to users in the Chinese mainland (excluding data centers), cross-border connections are established by using services provided by ISPs in the Chinese mainland. This reduces network latency. BGP (Multi-ISP) Pro is available only in the China (Hong Kong) and Japan (Tokyo) regions.

   If the information about an acceleration region is displayed in the list of acceleration regions, the acceleration region is added.

   For pay-as-you-go Global Accelerator instances, two accelerated IP addresses that belong to different zones are allocated to each acceleration region. They can receive client traffic at the same time to ensure high availability of the acceleration areas. The bandwidth of each accelerated IP address is equal to the bandwidth that is allocated to the acceleration region.

   Note

   An acceleration area takes effect approximately 2 minutes after it is added.

Modify an acceleration area

You can modify the bandwidth of an acceleration area for a standard Global Accelerator instance.

1. Log on to the GA 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 Edit Bandwidth.

4. In the Modify Bandwidth dialog box, change the bandwidth allocation method and the bandwidth of the acceleration region, and then click OK.

Delete an acceleration area

You can delete an acceleration area. After you delete the acceleration area, Global Accelerator no longer provides acceleration services for this area.

1. Log on to the GA 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 and acceleration region that you want to delete and click Actions in the Delete column.

4. In the Delete Accelerated IP Address message, click OK.
