HOL Blocking:
• HOL Blocking method Head that the heat Blocking.
You are watching: What is hol blocking? does it occur in input ports or output ports?
• It typically occurs at input ports.
• The phenomenon that HOL blocking occurs as soon as two packets are destined come the same position in the output queue.
• as soon as the switching towel chooses a packet, the other packet have to wait. If the packet which is in waiting state has another packet behind the then that packet likewise must stay in wait state.
• The packet in ~ the head that the heat blocks the second packet. Therefore, the second packet experiences HOL blocking.
The complying with figure explains the HOL Blocking:
The light color packet is headed by the dark fancy packet. Therefore, it experience HOL Blocking.
