Cloud Enterprise Network (CEN) can be used to connect network instances that are deployed in regions on a global scale. You are charged based on the region where a network instance is deployed. The Alibaba Cloud account that owns the network instance does not affect how fees are charged. You do not need to purchase a CEN bandwidth plan to connect network instances that are deployed in the same region. In this case, you can use the CEN service for free. To connect network instances across regions, you must purchase a CEN bandwidth plan and allocate bandwidth to the cross-region connection. This topic describes the billing of bandwidth plans.

The minimum bandwidth limit that you can specify for a bandwidth plan is 2 Mbit/s.
