  2. Go-Back-N ARQ - Wikipedia

    en.wikipedia.org/wiki/Go-Back-N_ARQ

    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.

  3. 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 ...

    Variations of ARQ protocols include Stop-and-wait ARQ, Go-Back-N ARQ, and Selective Repeat ARQ. All three protocols usually use some form of sliding window protocol to help the sender determine which (if any) packets need to be retransmitted. These protocols reside in the data link or transport layers (layers 2 and 4) of the OSI model.

  5. Flow control (data) - Wikipedia

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

    Sliding-window flow control is best utilized when the buffer size is limited and pre-established. During a typical communication between a sender and a receiver the receiver allocates buffer space for n frames (n is the buffer size in frames). The sender can send and the receiver can accept n frames without having to wait for an acknowledgement ...

    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 ...

    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.
