摘要： A network device includes a memory with a first queue and a second queue. A timing module generates a first priority timing signal or a second priority timing signal based on a clock signal. The clock signal is shared between the network device and other network devices in a non-arbitrary network. The network device includes a deblocking shaper or a blocking shaper. The deblocking shaper (i) forwards first protected data from the first queue, and (ii) generates a deblocking signal based on a first frame signal and the first priority timing signal. The blocking shaper (i) forwards one of second protected data and unprotected data from the second queue, and (ii) generates a first blocking signal based on a second frame signal and the second priority timing signal. A selector module selects the first frame or the second frame based on the deblocking signal and the first blocking signal.

摘要： A method for sending a frame of data from a first channel to a second channel comprises reserving q of n available buffers of m total buffers to the first channel. A frame that is received from the first channel in i of the q buffers is stored and the status is changed to unavailable. The frame is selectively assigned to the second channel based on a number of the buffers j assigned to the second channel and a number of the buffers h neither reserved nor assigned to any channel, wherein i+j≦m and h+q≦n. The i buffers storing the frame are assigned to the second channel if the frame is assigned to the second channel. The status of the i buffers is changed to available if the frame is subsequently sent over the second channel.
