A basic bandwidth plan provides bandwidth for data transfer over the Internet and within internal networks of Alibaba Cloud. However, basic bandwidth plans are not applicable to data transfer between the Chinese mainland and areas outside the Chinese mainland. To accelerate data transfer, you must purchase a basic bandwidth plan.

Bandwidth types

The following types of bandwidth are supported by basic bandwidth plans: basic, enhanced, and premium. The acceleration type, accelerated backend service, and acceleration scope of a basic bandwidth plan vary based on the bandwidth type, as described in the following table.
