Abstract: A network device includes a first port, a second port, and a traffic policer circuit. The traffic policer circuit is configured to provide a frame credit and a credit state associated with the frame credit, receive a start of a first frame of a first stream from the first port, and determine a first estimate frame length of the first frame based on the frame credit and credit state. After the first estimate frame length is generated and prior to an end of the first frame is received, the first frame is metered based on the first estimate frame length to mark the first frame with a first marking. After the end of the first frame is received, the frame credit and credit state are updated based on the first frame. The first frame is forwarded to the second port by policing the first frame based on the first marking.

Abstract: A network device includes a plurality of ports, a lookup circuit, and a traffic control circuit. The lookup circuit is configured to provide a first action for a first frame to be forwarded using a first forwarding path between a first set of two ports of the plurality of ports. The lookup circuit is further configured to and provide a second action for a second frame to be forwarded using a second forwarding path between a second set of two ports of the plurality of ports. The traffic control circuit configured to forward the first frame based on the first action and forward the second frame based on the second action.
