A method and arrangement for reclaiming buffers used to store frames, following the transmission of a frame, checks to determine whether the transmission of a frame is the last copy of that frame to be transmitted. If it is the last copy, or the only copy, the buffers storing that frame are reclaimed for reuse after the contents of each buffer are transmitted. If the frame is not the last copy, or it cannot be determined whether it is the last copy, then the frame is transmitted and a count of the number of transmitted copies of that frame is decremented. Once all of the copies have been transmitted, the buffer reclaiming process is initiated.
