Note

For billing details of services associated with resource plans, see the DCDN Pricing page.
Resource plans for outbound traffic, static HTTPS requests, and Edge WAF can be shared between Alibaba Cloud CDN and DCDN.

Resource plan	Description	Purchase URL
Outbound traffic	Offsets DCDN outbound traffic. WebSocket traffic is excluded. Important To use this resource plan to offset outbound traffic costs, your metering method must be `pay-by-data-transfer`. If your current metering method is `pay-by-bandwidth`, the remaining quota in the resource plan is frozen until you switch back to `pay-by-data-transfer`.	DCDN resource plans
Static HTTPS requests	Offsets static HTTPS requests for all domain names with HTTPS acceleration enabled.What is HTTPS acceleration?
Dynamic requests	Offsets dynamic HTTP requests for all accelerated domain names and dynamic HTTPS requests for all domain names with HTTPS acceleration enabled.
IP application acceleration (TCP/UDP) traffic	Offsets outbound traffic generated by IP application acceleration.What is IP application acceleration? Important IP application acceleration supports both `pay-by-data-transfer` and `pay-by-bandwidth` metering methods. This resource plan can only offset costs if your metering method is `pay-by-data-transfer`.
WebSocket traffic	Offsets outbound traffic generated by the WebSocket service.Configure WebSocket Important The WebSocket service supports both `pay-by-data-transfer` and `pay-by-bandwidth` metering methods. This resource plan can only offset costs if your metering method is `pay-by-data-transfer`.
DDoS mitigation plan	To enable Anti-DDoS, you must purchase a protection plan of a specific edition (Insurance or Unlimited).DDoS mitigation Important After you enable the protection service and add a domain name, an additional pay-as-you-go fee for scrubbed traffic applies. This fee is based on the DCDN outbound traffic generated by the domain name. For pricing details on scrubbed traffic, see Billing of DDoS mitigation.	Anti-DDoS

Outbound traffic

You can purchase multiple outbound traffic resource plans. If you have multiple plans, the one expiring soonest is deducted first. The system calculates outbound traffic usage every hour. Usage within the quota is deducted from the remaining balance. Overage is billed on a pay-as-you-go basis.

DCDN provides eight outbound traffic resource plans based on acceleration region. Each plan offsets usage only within its specified region; cross-region deductions are not supported.

Acceleration region	Description
Chinese mainland	For acceleration in the Chinese mainland.
Asia Pacific 1	For acceleration in Hong Kong (China), Macao (China), Taiwan (China), Japan, and Southeast Asian countries and regions excluding Vietnam and Indonesia.
Asia Pacific 2	For acceleration in India, Indonesia, South Korea, and Vietnam.
Asia Pacific 3	For acceleration in Australia and New Zealand.
North America	For acceleration in North America.
Europe	For acceleration in Europe.
Middle East and Africa	For acceleration in the Middle East and Africa.
South America	For acceleration in South America.

Static HTTPS requests

You can purchase multiple resource plans for static HTTPS requests. If you have multiple plans, the one that expires soonest is deducted first. The system calculates static HTTPS request usage every hour. Usage within the quota is deducted from the remaining balance. Overage is billed based on the number of static HTTPS requests.

Dynamic requests

A dynamic requests resource plan offsets both dynamic HTTP and dynamic HTTPS requests. You can purchase multiple plans. If you have multiple plans, the one expiring soonest is deducted first. The system calculates dynamic request usage every hour. Usage within the quota is deducted from the remaining balance. Overage is billed based on the number of dynamic HTTP and HTTPS requests.

IP application acceleration (TCP/UDP) traffic

This resource plan covers outbound traffic for IP application acceleration and currently supports deductions only in the Chinese mainland region. You can purchase multiple plans, and the one that expires soonest is deducted first.

The system calculates IP application acceleration (TCP/UDP) traffic usage every hour. Usage within the quota is deducted from the remaining balance. Overage is billed based on a tiered pricing model.

WebSocket traffic

This resource plan covers WebSocket outbound traffic. Like standard outbound traffic plans, WebSocket traffic plans are region-specific and available for eight acceleration regions. Each plan offsets usage only within its specified region. You can purchase multiple plans, and the one that expires soonest is deducted first.

The system calculates WebSocket traffic usage every hour. Usage within the quota is deducted from the remaining balance. Overage is billed based on a tiered pricing model.

Edge WAF requests plan (old version)

After you enable the WAF feature, Edge WAF inspects all requests to the specified domain name and aggregates the request count at the account level. The system calculates WAF request usage every hour. Usage within the quota is deducted from the remaining balance. Overage is billed based on the number of Edge WAF requests.

The Edge WAF requests plan (old version) currently supports deduction only in the Chinese mainland region. You can purchase multiple plans, and the one that expires soonest is deducted first.

Edge WAF SeCU plan (new edition)

The new edition of Edge WAF is a pay-as-you-go service billed by Security Capacity Units (SeCUs). All billable items are converted into SeCUs.

You can purchase multiple Edge WAF SeCU plans. If you have multiple plans, the one that expires soonest is deducted first. The system calculates SeCU consumption every hour. Usage within the quota is deducted from the remaining balance. Overage is billed based on the number of consumed SeCUs.

DDoS mitigation plan

DDoS protection helps defend your accelerated domain names against DDoS attacks. To enable Anti-DDoS, you must purchase a protection plan of a specific edition (Insurance or Unlimited).

After you enable the protection service and add a domain name, an additional pay-as-you-go fee for scrubbed traffic applies. This fee is based on the DCDN outbound traffic generated by the domain name. For pricing details on scrubbed traffic, see Billing of DDoS mitigation.
