Transfer acceleration efficiently speeds up the uploads and downloads of objects in a bucket over long distances. For example, if you are located in the Chinese mainland, you can enable transfer acceleration when you upload objects to or download objects from a bucket that is located outside the Chinese mainland. This way, the data uploads or downloads are accelerated. After transfer acceleration is enabled for a bucket, acceleration endpoints are generated for the bucket. You are charged transfer acceleration fees when you use the acceleration endpoints to upload data to or download data from the bucket. After you enable transfer acceleration for a bucket, the default endpoint of the bucket remains available. You are not charged transfer acceleration fees when you use the default endpoint to upload data to or download data from the bucket.
Unit price
This topic describes the billable items and billing methods of transfer acceleration. For more information about the unit price of the billable items, see Object Storage Service pricing.
Billable items
You are separately charged transfer acceleration fees and fees for outbound traffic over the Internet. For example, if you use an acceleration endpoint to download 1 GB of data from a bucket located in the China (Hangzhou) region to the Germany (Frankfurt) region, you are charged transfer acceleration fees (AccO2MOut) for 1 GB of data and fees for outbound traffic over the Internet for 1 GB of data.
Note
You are billed on an hourly basis for the following billable items. Bills are generally generated after a billing cycle ends. The time when bills are generated is determined by the system.
Upload acceleration traffic
Billing item | Code | Billing rule |
Billing item | Code | Billing rule |
Transfer acceleration | AccM2MIn | You are charged fees based on the traffic that is generated when you use an acceleration endpoint to upload data between regions in the Chinese mainland. |
AccM2OIn | You are charged fees based on the traffic that is generated when you use an acceleration endpoint to upload data from regions in the Chinese mainland to regions outside the Chinese mainland. |
AccO2MIn | You are charged fees based on the traffic that is generated when you use an acceleration endpoint to upload data from regions outside the Chinese mainland to regions in the Chinese mainland. |
AccO2OIn | You are charged fees based on the traffic that is generated when you use an acceleration endpoint to upload data between regions outside the Chinese mainland. |

Billing methods
Instructions for selecting a billing method
We recommend that you refer to the following table to learn about the features and scenarios of different billing methods. This helps you select an appropriate billing method.
Billing method | Description | Feature | Scenario |
Billing method | Description | Feature | Scenario |
Pay-as-you-go | By default, you are charged for all billable items based on the pay-as-you-go billing method. You are charged for the actual usage of each billable item. Pay-as-you-go allows you to use resources first and pay for them afterwards. | The usage of the upload or download acceleration traffic fluctuates and is difficult to predict. | Unstable amount of data to be transmitted: The amount of data to be uploaded or downloaded over long distances is small, and the data scale is difficult to predict. Temporary or one-time accelerated upload or download requirements
|
Transfer acceleration plan | A transfer acceleration plan is a favorable billing method that can be used to offset fees for various billable items of transfer acceleration. When bills are being settled, transfer acceleration plans have higher priority than the pay-as-you-go billing method. Before you can use transfer acceleration plans to offset fees, you must purchase transfer acceleration plans. | The usage of the upload or download acceleration traffic is stable and predictable. | Business on a global scale Frequent uploads and downloads of large amounts of data or large objects over long distances (such as data transmission from regions in the Chinese mainland to regions outside the Chinese mainland)
