General description

Subscriber traffic is defined by a list of IP addresses or CIDR. Subscriber traffic can have Subcribers channel policing for IPv4 and IPV6 applied, but it is also subject to the policing of the General or Virtual channel in which the Subscriber resides. For more details, see General description of policing.

Policing is applied to 8 traffic classes, configured via Traffic prioritization depending on protocols and directions.

The mapping of a protocol to its class is also regulated by the option (class <-> priority). This approach makes it possible to combine external and internal policers in a compatible way.

Two policing mechanisms are available to choose from:

TBF without hierarchy (Token Bucket Function), used to limit/block a specific policing class. Bandwidth limitation with burst support.

HTB with hierarchy for 8 classes (Hierarchical Token Bucket), used for prioritization by traffic classes. Bandwidth limitation with borrowing.

Creation and assignment of policing (tariff plan) is performed via Subscriber Management (SM) commands.

Applying tariff plans to a subscriber is possible either using the PUSH method or through RADIUS for BRAS.
