A method and apparatus for sending a frame of data from a first channel to a second channel a memory buffers m for storing a frame, in which n have an available status and p have an unavailable status, comprises reserving to the first channel the n buffers having the available status when q of the buffers reserved to the first channel is less than a capacity of reserve module buffers r, when a frame is received, storing the frame in i and changing the status to unavailable, selectively assigning the frame to the second channel based on s of the q buffers; if the frame is assigned to the second channel, the frame is sent to the second channel from the i buffers and the status of the i buffers is changed to available; if is not assigned to the second channel, the frame is discarded and the status of the i buffers is changed to available.
