====== General description ======
{{indexmenu_n>1}}
The bandwidth control for subscribers is similar to [[dpi:dpi_options:opt_shaping|the overall bandwidth control]]. All options are available:
  - Bandwidth limitation by the traffic classes (for example: limit torrents
  - Traffic's prioritization within the subscriber's bandwidth with borrowing (HTB) or as "pipes" (TBF)

Protocols are divided into 8 classes. This number is limited by number of priorities set up by the option [[dpi:dpi_options:opt_priority|"Protocol dependent prioritizing of traffic"]].
Placing of a particular protocol into its class is controlled by the same option: ([[dpi:dpi_options:opt_priority:dscp_table|class <-> priority]]).

The assignment of traffic control policies for subscribers is supported by [[dpi:dpi_components:platform:subscriber_management|Subscriber Management,SM]].

Application of tariff plans per subscriber is possible using the [[dpi:dpi_components:platform:dpi_billing|PUSH method]] or via RADIUS for [[dpi:bras_bng:general_setup#fastdpi_l3_bras_setup|BRAS L3]] and [[dpi:bras_bng:general_setup#fastdpi_l2_bras_setup|BRAS L2]].
