Head-of-line blocking (HOL blocking) is a performance-limiting phenomenon that occurs when a line of packets are held up by the first packet.The switches with input buffering can suffer HOL blocking because only the oldest packet is available for forwarding (FIFO). The more recent arrivals cannot be forwarded if the oldest packet cannot be forwarded because its destination output is busy (Congestion). The phenomenon can have severe performance-degrading effects. With HoL Prevention, the new arrivals could potentially be forwarded around the stuck oldest packet to their respective destinations..
