What Do I Do If My Service Traffic Exceeds the Protection Bandwidth?

If your actual service traffic exceeds the protection bandwidth you purchased, your traffic may be limited, packets may be discarded randomly, and CFW may be bypassed automatically. Some of your services may be unavailable, frozen, or may respond very slowly.

In this case, purchase more protection capacity as needed to provide sufficient protection bandwidth. If your service traffic fluctuates greatly, determine the protection bandwidth to purchase based on the maximum value of Outbound 95th Percentile Bandwidth or Inbound 95th Percentile Bandwidth in the Operations Dashboard of the Dashboard page.

For details about how to purchase an expansion package, see Adding the EIP Protection Capacity.

• You can configure high traffic warning in CFW. An alarm will be sent if your service traffic reaches the specified proportion of purchased bandwidth. For more information, see Alarm Notification.
