Abstract
A policing engine for use in a telecommunication equipment shelf is operative to control the rate at which customer-sourced ATM packets are passed to buffers associated with different classes of service to which customers may subscribe. The policing engine examines the rate at which ATM cells are supplied to it from the line card ports, whether the cells are AAL5 cells, and how full are the buffers into which the cells are to be written. If cells are supplied to the policing engine at a rate faster than prescribed peak or sustained cell rates, or if the cell buffer begins to fill up, the policing engine controllably discards incoming cells, thereby effectively 'throttling' the cell flow rate through it.
