A network device including first and second queues, a timing module, and deblocking and blocking shapers. The first and second queues respectively store first and second frames. The timing module generates: a first priority timing signal indicating when transmission of the first frame is permitted; and a second priority timing signal indicating when transmission of the second frame is not permitted. The deblocking shaper, based on the first priority timing signal, permits transmission of the first frame during a predetermined window. The blocking shaper includes a counter indicating an amount of time until a start of the predetermined window. The blocking shaper, based on the second priority timing signal, a value of the counter and a size of the second frame, determines whether to permit transmission of the second frame prior to the predetermined window or block forwarding of the second frame until after the predetermined window. |
