The invention includes a method and apparatus for performing packet policing by operating an input queue as a leaky bucket queue. The method includes storing a received packet in a shared memory shared by a plurality of input queues and a plurality of output queues, storing a corresponding packet pointer for the packet in one of the plurality of input queues, transferring the packet pointer from the one of the plurality of input queues to one of the plurality of output queues associated with an output port to which the packet is assigned, and transmitting the packet from the output port using the packet pointer. The packet pointer identifies a storage location in the shared memory. The packet pointer is removed from the one of the plurality of output queues and used for retrieving the packet from the shared memory.
