### Adjusting Hosting Plan Traffic Settings

Parallels Business Automation - Standard provides special tools for traffic accounting by classes. A network class is a range of IP addresses for which traffic is counted and charged.

Parallels Business Automation - Standard traffic accounting allows having up to 15 traffic classes including two default ones (Class 1 and Class 2). Different traffic rates can be set for each traffic class in the frame of different hosting plans. Class 1 is for non-chargeable Container internal traffic and therefore, it is not even shown within hosting plans settings. Traffic pricing starts from the Class 2.

The default traffic Class 2 that matches any IP address cannot be disabled and thus, it is always available for all hosting plans the traffic accounting is applicable.

To enable traffic accounting for a hosting plan subscribers, you must enable one or more traffic classes for this hosting plan. Please note that to be available for the use in the frame of a hosting plan (i.e., to be shown within a hosting plan settings), a traffic class must be enabled globally. You can create more and/or enable existing traffic classes in Service Director - Service Level manager - Traffic Classes.

The list of all globally enabled traffic classes plus the default Class 2 that is always enabled is shown first on the Traffic step of a hosting plan creation wizard and after a hosting plan is created, the traffic accounting can be adjusted under the Traffic tab in a hosting plan properties.

Note: For Plesk Client or Plesk Domain hosting plans, only Class 2 is applicable.

Traffic is always accounted monthly, without respect to the subscription period a customer selects. And traffic limits are set per month. Customers pay for traffic usage over the included value (if overusage takes place) each month. A billing month in this case means the same day next month. For example, if customer has set up a subscription on October 5, then the traffic is accounted for the October 5 - November 5 period and the traffic overusage invoice (if needed) will be issued on November 5.

Adjust the traffic accounting settings for the hosting plan:

To enable traffic accounting by classes for this hosting plan, check the Enable this traffic class for this hosting plan box at a traffic class form.

Important: Please keep in mind that Containers traffic accounting for Parallels Virtuozzo Containers for Windows is possible only by the Class 2.

The Create an overusage invoice at the end of every billing month instead of limiting traffic with the included value checkbox serves for switching the traffic accounting from the metered mode (the box checked) to the non-metered mode (the box cleared). The metered traffic accounting mode allows using traffic over the Included amount but up to the Maximum amount and paying for the traffic used over the Included amount at the end of month. The non-metered traffic accounting mode allows using traffic only up to the Included amount and in case a customer needs more traffic, he/she must order more at an additional fee, but no greater than the Maximum amount; after an order is paid, traffic will be provided.

To set the traffic limits and prices, specify the values in the fields next to a traffic type name:

Select the units to measure traffic from the Units drop-down menu.

If you do not want to limit traffic for the hosting plan subscribers, check the Unlim box next to the corresponding traffic type. If you want to set limits and prices, clear the Unlim box and enter limits and rates.

Enter the monthly traffic amount included in the hosting plan price into the Included amount field.

Enter the monthly traffic limit into the Maximum amount field. This will be the maximal traffic value allowed for customers subscribed for this hosting plan.

Enter the price per additional traffic unit (selected from the Units drop-down menu) into the Overuse rate/Cost for additional field.
