The public network bandwidth can be billed by fixed bandwidth or by traffic usage.

By fixed bandwidth: You will be billed based on the bandwidth you specify. Your outbound bandwidth will not exceed the bandwidth specified.
By traffic usage: You will be billed on a pay-per-use basis. Only traffic used in the outbound direction will be billed.
To prevent excessive fees due to sudden traffic spikes, you can set a peak value for the outbound bandwidth.

You can select the billing mode based on bandwidth usage.
