Methods and apparatus for implementing flow control with reduced buffer usage for network devices. In response to detection of flow control events, transmission of a data unit or segment such as an Ethernet frame is preempted in favor of a flow control message, resulting in aborting transmission of the frame. Data corresponding to the entirety of the frame is buffered at the transmitting station until the frame has been transmitted (or after a delay), enabling retransmission of the aborted frame. Preemption of frames in favor of flow control messages results in earlier responses to flow control events, enabling the size of buffers to be reduced.

Over the years, batons have not changed much in size or shape. The ends of the baton are still rubber with a steel shaft in between. Little has been done to prevent the baton from slipping out of the twirler's fingers due to moisture or to keep the baton from rolling away when dropped. The primary essence of this patent is to reduce rolling action and bounce when dropped as well as slippage due moisture. This patent introduces a newly designed ball and tip that is in the general shape of a tetrahedron that transitions into a frustum shape that connects the ends to the shaft. The functional shape of baton ends appears to be an equilateral triangle when viewed looking down the axis of the baton shaft. The effect of this design is that three flat surfaces on each end of the baton are oriented so that the flats are in the same plane with each other, which creates resistance to rolling. A non-slip surface has also been created in the center of the baton to reduce the tendency of the baton to slip in wet conditions but will not harm the twirlers fingers. Low resilient synthetic rubber ends have as well been incorporated into the design to diminish the bounce effect when dropped.
