  2. Selective Repeat ARQ - Wikipedia

    en.wikipedia.org/wiki/Selective_Repeat_ARQ

    Selective Repeat is part of the automatic repeat request (ARQ). With selective repeat, the sender sends a number of frames specified by a window size even without the need to wait for individual ACK from the receiver as in Go-Back-N ARQ. The receiver may selectively reject a single frame, which may be retransmitted alone; this contrasts with ...

    The Transmission Control Protocol uses a variant of Go-Back-N ARQ to ensure reliable transmission of data over the Internet Protocol, which does not provide guaranteed delivery of packets; with Selective Acknowledgement (SACK), it uses Selective Repeat ARQ. IEEE 802.11 wireless networking uses ARQ retransmissions at the data-link layer. [1]

    Go-Back-N ARQ is a specific instance of the automatic repeat request (ARQ) protocol, in which the sending process continues to send a number of frames specified by a window size even without receiving an acknowledgement (ACK) packet from the receiver.

    Three types of ARQ protocols are Stop-and-wait ARQ, Go-Back-N ARQ, and Selective Repeat ARQ. ARQ is appropriate if the communication channel has varying or unknown capacity , such as is the case on the Internet.

  6. Flow control (data) - Wikipedia

    en.wikipedia.org/wiki/Flow_control_(data)

    Selective repeat is a connection oriented protocol in which both transmitter and receiver have a window of sequence numbers. The protocol has a maximum number of messages that can be sent without acknowledgement. If this window becomes full, the protocol is blocked until an acknowledgement is received for the earliest outstanding message.

    The extremely popular HDLC protocol uses a 3-bit sequence number, and has optional provision for selective repeat. However, if selective repeat is to be used, the requirement that n t +n r ≤ 8 must be maintained; if w r is increased to 2, w t must be decreased to 6. Suppose that w r =2, but an unmodified transmitter is used with w t =7, as is ...
