Cloud Enterprise Network billing-Cloud Enterprise Network(CEN)-阿里云帮助中心

To enable network interconnectivity using Cloud Enterprise Network (CEN), first create a transit router (TR) in CEN, then use the TR to connect your network instances. CEN charges for these network instance connections as follows:

Intra-region connections incur a connection fee and a traffic processing fee.
Inter-region connections incur an inter-region bandwidth fee.

Billing items

Billing item	billing rule	Formula	Minimum billing cycle	Billing method
Connection fee	Billed based on the number and duration of intra-region connections. Intra-region connections include VPC connections, ECR connections, VBR connections, and VPN connections. Duration is the time elapsed from when a network instance connection is created until it is deleted.	Unit price (CNY/connection/hour) × number of intra-region connections × usage duration (hours)	1 hour. If usage is less than 1 hour, it is billed as 1 hour.	Pay-as-you-go
Traffic processing fee	Billed based on traffic ingressing into the transit router from intra-region connections. Multicast traffic is not subject to this rule. For details, see Multicast billing.	Unit price (CNY/GB) × volume of traffic ingressing into the transit router from intra-region connections (GB)	1 hour
Inter-region bandwidth fee	Select pay-by-data-transfer: Billed based on inter-region traffic egressing from each transit router. Charges are settled by the Cloud Data Transfer (CDT) service.	Unit price (CNY/GB) × volume of inter-region traffic egressing from the transit router (GB)	1 hour
Inter-region bandwidth fee	When billed by bandwidth: First purchase a bandwidth plan, then allocate bandwidth from the plan to your inter-region connections. Each bandwidth plan is billed based on its bandwidth value and subscription duration.	Unit price (CNY/Mbps/month) × bandwidth value (Mbps) × subscription duration (months)	1 month	Subscription

How to choose a billing method for inter-region bandwidth fees?

Billed by data transfer: Best for workloads with frequent and unpredictable traffic peaks. Examples: temporary scaling, testing, video conferencing, and real-time gaming.
Billed by bandwidth: Best for stable, long-running workloads. Examples: file transfer, data migration, and data synchronization.

Note

For proof of concept (POC) testing of inter-region bandwidth, we recommend billing by data transfer. This option provides 1 Gbps bandwidth by default. If your total inter-region data transfer charges during a billing cycle are less than CNY 0.01 (assuming the link type is “Gold” with an inter-region traffic fee of CNY 0.48/GB, this equals approximately 20 MB of traffic), the amount is rounded down to zero, letting you complete testing without paying inter-region traffic fees. For more information, see How are rounded-down amounts calculated in bills, and what are the rounding rules?.

Connection fees and traffic processing fees are billed hourly on the hour. If you delete a network instance connection between hourly boundaries, you still incur charges for the full current hour. For example, if you delete a transit router connection at 10:35, you are billed for the full 10:00–11:00 hour.

Billed by bandwidth

When billed by bandwidth:

Inter-region links support only the “Gold” link type.
Tiered pricing applies. Total cost is the sum of fees for each tier. Visit the bandwidth plan purchase page to view pricing for your desired bandwidth.

Unit prices per tier are shown below:

Connected areas	Inter-region bandwidth tiered unit price (CNY/Mbps/month)
Connected areas	(0–100 Mbps]	(101–1000 Mbps]	>1000 Mbps
Chinese mainland–Chinese mainland	220	80	50
Asia-Pacific–Asia-Pacific	180	120	100
Asia-Pacific–North America	470	280	240
Asia-Pacific–Europe	470	280	240
Asia-Pacific–Middle East	1100	670	580
North America–North America	180	120	100
North America–Europe	470	280	240
North America–Middle East	1100	670	580

Chinese mainland–North America	1110	670	580
Chinese mainland–Europe	1000	610	530
Chinese mainland–Middle East	1100	670	580

Inter-region bandwidth tiered pricing example

Assume you purchase one bandwidth plan instance connecting two regions within the Chinese mainland, with a peak bandwidth of 110 Mbps and a subscription duration of 1 month. The cost is:

CNY 220/Mbps/month × 100 Mbps × 1 month + CNY 80/Mbps/month × 10 Mbps × 1 month = CNY 22,800

Note

Starting March 31, 2021, Alibaba Cloud offers a free trial of CEN prepaid bandwidth plans for new Alibaba Cloud account holders. The trial lasts 1 month and includes up to 5 Mbps of free bandwidth. For more information, see Free trial for CEN prepaid bandwidth plans.

Link types

Inter-region links support two types—“Gold” and “Platinum”—each offering different service levels:

Link type	Service availability	Use cases
Gold	99.95%	Suitable for workloads insensitive to link quality. Examples: data synchronization, file transfer.
Platinum	99.995%	Suitable for workloads highly sensitive to jitter and latency, requiring high link quality. Examples: stock trading, online voice, video conferencing, real-time gaming.

Billing examples

Example 1: Intra-region VPC interconnectivity

As shown above, assume you create one transit router in the China (Hangzhou) region and connect two VPCs (VPC1 and VPC2) within the same region. Over one month, VPC1 sends 100 GB of traffic through the transit router to VPC2, while VPC2 sends no data to VPC1. Billing is calculated as follows:

Connection fee:

Two VPC connections (intra-region) at CNY 0.35/connection/hour (Chinese mainland)
Assume 30 days per month: 30 × 24 = 720 hours
CNY 0.35/connection/hour × 2 connections × 720 hours = CNY 504

Traffic processing fee:

Unit price: CNY 0.13/GB
The traffic flowing from VPC1 into Transit Router is 100 GB, and the traffic flowing from VPC2 into Transit Router is 0 GB.
CNY 0.13/GB × (100 GB + 0 GB) = CNY 13

Total for 1 month:

Connection fee: CNY 504
Traffic processing fee: CNY 13
Total payable: CNY 504 + CNY 13 = CNY 517

Example 2: Inter-region VPC interconnectivity

As shown above, assume you create two transit routers in one CEN—one in China (Hangzhou) and one in China (Shanghai). Each region has one VPC (VPC1 and VPC2), each connected to its local transit router. The two transit routers are linked via an inter-region connection. Over one month, VPC1 sends 100 GB of traffic to VPC2, while VPC2 sends no data to VPC1. Billing is calculated as follows:

Connection fee:

Two VPC connections (intra-region) at CNY 0.35/connection/hour (Chinese mainland)
Assume 30 days per month: 30 × 24 = 720 hours
CNY 0.35/connection/hour × 2 connections × 720 hours = CNY 504

Traffic processing fee:

Unit price: CNY 0.13/GB
Traffic ingressing into transit routers: 100 GB from VPC1 to transit router 1, 0 GB from VPC2 to transit router 2
CNY 0.13/GB × (100 GB + 0 GB) = CNY 13

Inter-region bandwidth fee:

Assume billing by data transfer with “Gold” link type. The inter-region traffic unit price is CNY 0.48/GB (within the Chinese mainland).
Inter-region traffic egressing from transit routers: 100 GB from transit router 1 to transit router 2, 0 GB from transit router 2 to transit router 1
CNY 0.48/GB × (100 GB + 0 GB) = CNY 48

Total for 1 month:

Connection fee: CNY 504
Traffic processing fee: CNY 13
Inter-region bandwidth fee: CNY 48 (billed by data transfer)
Total payable: CNY 504 + CNY 13 + CNY 48 = CNY 565

Note

In the same scenario, if billed by bandwidth, the inter-region bandwidth fee for Chinese mainland connections is CNY 220/Mbps/month. Assuming a bandwidth plan of 10 Mbps, the inter-region bandwidth fee would be CNY 220/Mbps/month × 10 Mbps = CNY 2,200. Adding connection and traffic processing fees, the 1-month total would be CNY 504 + CNY 13 + CNY 2,200 = CNY 2,717.

FAQ

CCN connections are intra-region connections but can only be created with Basic Edition transit routers. They do not incur connection or traffic processing fees.
