Why Is the Traffic Usage in a Traffic Package Different from That Shown in Analytics?

Possible causes:

1. CDN statistics on the Analytics page are 1 hour later than real-time data. However, there is a 4-hour delay before traffic can be billed. Therefore, the bill time is later than the statistical time. As a result, traffic displayed on the Analytics page is greater than that deducted from the current traffic package.
   For example, if 20 MB of traffic is consumed from 12:00:00 to 13:00:00,

   • a bill is generated at 17:00:00 for this.
   • the 20 MB of traffic is added to the Analytics page at 14:00:00.

     However, the 20 MB of traffic is billed until 17:00:00. As a result, the data will be inconsistent.

     

     If you are billed by traffic on a pay-per-use basis, traffic deducted may also be different from that displayed on the Analytics page.

2. The Analytics page on the CDN console displays the logged traffic statistics of acceleration domain names. These statistics are obtained from logs at the application level. However, the billable traffic (the actual network traffic) is 7% to 15% higher than the displayed statistics on the Analytics page because TCP/IP packet headers and TCP retransmissions also need to be counted in. Therefore, the billable traffic will be typically 10% higher than the statistics displayed on the CDN console. As a result, the used traffic in the traffic package is higher than that displayed on the Analytics page.
