When you use an Enterprise Edition transit router to connect network instances, you are charged a connection fee and a data transfer fee based on the types of the network instances. This topic describes how connection fees and data transfer fees are charged when you use Enterprise Edition transit routers.

Billing rules

Transit routers are provided with two editions based on regions: Basic Edition and Enterprise Edition. Only Enterprise Edition transit routers are charged. For more information about the regions that support Enterprise Edition transit routers, see Regions and zones that support Enterprise Edition transit routers.

When you use an Enterprise Edition transit router to connect network instances, you are charged a connection fee and a data transfer fee based on the types of the network instances.
  • When you connect an Enterprise Edition transit router to a virtual private cloud (VPC), you are charged a connection fee and a data transfer fee.
  • When you connect an Enterprise Edition transit router to a virtual border router (VBR), you are charged a connection fee.
    Note You are not charged a data transfer fee when you connect a transit router to a VBR. For more information about when Alibaba Cloud starts charging the data transfer fee for VBRs, see the announcements of Alibaba Cloud.
  • When you connect an Enterprise Edition transit router to a Cloud Connect Network (CCN) instance, you are not charged a connection fee or data transfer fee.

Enterprise Edition transit routers are billed based on the following rules:

  • Billable items:
    • Connections: You are charged a connection fee based on the total number of VPCs and VBRs that are connected to all your Enterprise Edition transit routers.
    • Data transfer: You are charged a data transfer fee based on the total amount of data transferred from a VPC to an Enterprise Edition transit router. Data transfer from an Enterprise Edition transit router to a VPC is free of charge.
  • Billing method: pay-as-you-go

    The pay-as-you-go billing method allows you to pay for the resource usage after each billing cycle ends.

  • Billing cycle: 1 hour

    If you use an Enterprise Edition transit router for less than 1 hour, you are charged for 1 hour.

Billing example

The following example shows how Enterprise Edition transit routers are billed:

A company uses Cloud Enterprise Network (CEN) to connect the following network instances. The network instances can communicate with each other.

Billing example
Fees that are charged in Area A, Area B, and Area C:
  • Area A:
    • You are charged a connection fee for connecting the Enterprise Edition transit router in the China (Hangzhou) region to the VPC in the China (Hangzhou) region.
    • You are charged a data transfer fee for transmitting data from the VPC in the China (Hangzhou) region to the Enterprise Edition transit router in the China (Hangzhou) region.
  • Area B: You are charged a connection fee for connecting the Enterprise Edition transit router in the China (Hangzhou) region to the VBR in the China (Hangzhou) region. You are not charged for transmitting data between the Enterprise Edition transit router in the China (Hangzhou) region and the VBR in the China (Hangzhou) region.
  • Area C: To enable the network instances across regions in mainland China to communicate with each other, you must purchase a bandwidth plan for these regions. Then, allocate bandwidth for the cross-region data transmission between the China (Hangzhou) and China (Qingdao) regions. For more information about the billing of CEN bandwidth plans, see Billing of bandwidth plans. No bandwidth plan is required if you do not want to transmit data across regions.
