This topic describes the billing methods of CDN basic services and related precautions.

CDN basic services have two billing options, including PayByTraffic and PayByBandwidth. For more information about pricing, see CDN pricing.

Billing methods

Billing method Description Scenario
Peak bandwidth CDN basic services are billed based on the daily peak bandwidth. A bandwidth value is calculated at five minute intervals. A total of 288 values can be obtained each day. The maximum value is used for billing purposes. The CDN traffic curve is relatively flat, and the daily bandwidth utilization exceeds 30%.
Traffic CDN basic services are billed based on the daily outbound traffic from CDN nodes. Large fluctuations and bandwidth spikes exist in the CDN traffic curve. The daily bandwidth utilization is less than 30%.
Note
  • Bandwidth utilization = Used traffic (GB)/(Peak bandwidth (Mbit/s) × 10.54). If the bandwidth is 1 Mbit/s and the daily bandwidth utilization is 100%, the generated traffic is 10.54 GB.
  • Only the outbound traffic (downstream traffic) from CDN nodes is billed.

Precautions

  • The billed traffic is more than the traffic recorded in logs. The traffic recorded in CDN logs is the traffic recorded in application-layer logs. TCP/IP packet headers and TCP retransmissions consume traffic. Therefore, the generated network traffic is higher than the traffic recorded in application-layer logs.
  • If you spend more than CNY 100,000 on CDN services per month, you can choose a monthly billing method. This method is more cost-effective. You can contact us by submitting a ticket or dialing the pre-sales number (95187 ext. 1).
