Billing Rules

Items Charged

Billing ItemDescription
UWAN Instance FeeWhen creating a UWAN virtual router, the corresponding instance fee is charged according to the selected UWAN instance model. It is calculated based on the instance type, quantity, and purchase cycle.
UWAN Bandwidth Access FeeThe UWAN instance and the external network are billed separately. If the external network opts for bandwidth-based billing, an bandwidth access fee will be incurred. The bandwidth fee is calculated as the configured line bandwidth value * bandwidth unit price * purchase cycle.
UWAN Traffic Access FeeThe UWAN instance and the external network are billed separately. If the external network chooses traffic-based billing, an traffic access fee will be generated. Traffic is post-paid and calculated daily based on the actual traffic usage.

Billing Modes

Billing ModeBilling MethodBilling UnitApplicable Scenarios
Fixed BandwidthPre-paymentUSD/month, with a minimum purchase duration of 1 monthSuitable for scenarios with stable bandwidth
Traffic BillingPost-paymentUSD/month (instances should be pre-paid, with a minimum purchase duration of 1 month);
USD/GB, traffic fees are calculated based on the total actual traffic used per day		Suitable for scenarios with bursty business

  • Fixed Bandwidth Billing

Billing Method

Billing method: Prepaid;

Billing Cycle

The billing cycle is monthly/yearly, and the bill is generated immediately upon purchase;

Billing Algorithm

The total cost = (Monthly unit price of the instance + Monthly unit price of the bandwidth * Bandwidth quantity) * (Effective time / Total duration of the billing month);

If there is an upgrade or downgrade adjustment of the bandwidth within the bandwidth package in a month, the billing before the time node of the adjustment will still be calculated according to the original fixed bandwidth, and the billing after that will be calculated according to the new fixed bandwidth. At the same time, corresponding refund or supplementary payment operations will be carried out;

The billing time is accurate to the second;

If the user's purchase cycle is not an integer natural month, the final bandwidth fee for that month = the original bandwidth fee * the number of effective days / the number of days in the billing month.

Billing Example

For example: Customer A purchased a UWAN with a configuration of 300M in the bandwidth billing mode at 10:30:00 a.m. on August 5th. Then the bill of Customer A for this month is as follows:

The unit price of the UWAN instance: 12.86 USD per month;        

The monthly unit price of the bandwidth: approximately 15.71 USD/M/month; 

The bandwidth value: 300M;    

The coefficient of the effective time of the current month: 26 days, 13 hours and 30 minutes, 0 seconds / 31 days = (2,246,400 + 46,800 + 1,800) / 2,678,400 = 0.8569; 

(There are 31 days in August in total. The user made the purchase at 10:30:00 a.m. on August 5th. The actual usage time of the customer is from 10:30:00 a.m. on August 5th to 24:00 on that day plus the whole days from August 6th to August 31st, which is 26 days, 13 hours and 30 minutes, 0 seconds in total, and 2,295,000 seconds in total.)

The actual bill for this month: (12.86 + 300 * 15.71) * 0.8569 = 4048.69 USD

  • Traffic Billing

Billing Method

Billing method: instance prepaid + traffic postpaid;

Billing Cycle

The UWAN instance is prepaid in units of months or years; The UWAN traffic is postpaid in units of days;

Billing Algorithm

The total cost = instance fee + traffic fee; the instance fee is settled once at the purchase cycle, and the traffic fee is settled daily.

Instance fee = number of instances * unit price of instance * (effective time / total billing month duration).

Traffic fee = daily total traffic * unit price of traffic.

Billing Example

For example: Customer B purchased a UWAN with a configuration of 300M in the traffic billing mode at 10:30:00 a.m. on August 5th. Then the bill of Customer B for this month is as follows:

The upper limit of the bandwidth: 300M;

The monthly unit price of the UWAN instance is: 12.86 USD/instance/month; 

The unit price of the UWAN traffic: 0.13 USD/GB;   

The monthly traffic usage: 10,000 GB;
        
The coefficient of the effective time of the current month: 26 days, 13 hours and 30 minutes, 0 seconds / 31 days = (2,246,400 + 46,800 + 1,800) / 2,678,400 = 0.8569;

The instance bill for this month: 12.86 * 0.8569 + 0.13 * 10,000 = 1311.02 USD
