The job of moving the packets to particular ports is performed by switching fabrics. Switching can be approached in number of ways: 4.1 Switching via Memory: Head-of-line blocking (HOL blocking) in computer networking is a performance-limiting phenomenon that occurs when a line of packets is held up in a queue by a first packet. Examples include input buffered network switches, out-of-order delivery and multiple requests in HTTP pipelining. See more A switch may be composed of buffered input ports, a switch fabric and buffered output ports. If first-in first-out (FIFO) input buffers are used, only the oldest packet is available for forwarding. If the oldest packet cannot be … See more Head-of-line blocking can occur in reliable byte streams: if packets are reordered or lost and need to be retransmitted (and thus arrive out-of-order), data from sequentially later parts of the … See more • Bufferbloat • FIFO • HTTP pipelining • Network scheduler See more Out-of-order delivery occurs when sequenced packets arrive out of order. This may happen due to different paths taken by the packets … See more One form of HOL blocking in HTTP/1.1 is when the number of allowed parallel requests in the browser is used up, and subsequent requests need to wait for the former ones to complete.
