Policer (Rate Metering) Overview
The IP-20 switching fabric supports hierarchical policing on the logical interface
level. You can define up to 250 rate meter (policer) profiles.
Note:
Policing on the service point level, and the service point and CoS level,
is planned for future release.
IP-20's policer mechanism is based on a dual leaky bucket mechanism (TrTCM).
The policers can change a frame’s color and CoS settings based on CIR/EIR +
CBS/EBS, which makes the policer mechanism a key tool for implementing
bandwidth profiles and enabling operators to meet strict SLA requirements.
The output of the policers is a suggested color for the inspected frame. Based on
this color, the queue management mechanism decides whether to drop the frame
or to pass it to the queue.
