  2. Sliding window protocol - Wikipedia

    en.wikipedia.org/wiki/Sliding_window_protocol

    A sliding window protocol is a feature of packet-based data transmission protocols. Sliding window protocols are used where reliable in-order delivery of packets is required, such as in the data link layer ( OSI layer 2 ) as well as in the Transmission Control Protocol (i.e., TCP windowing ).

  3. Automatic repeat request - Wikipedia

    en.wikipedia.org/wiki/Automatic_repeat_request

    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.

  4. Stop-and-wait ARQ - Wikipedia

    en.wikipedia.org/wiki/Stop-and-wait_ARQ

    A diagram of the Stop-and-Wait ARQ protocol and its operation in various cases. Stop-and-wait ARQ, also referred to as alternating bit protocol, is a method in telecommunications to send information between two connected devices. It ensures that information is not lost due to dropped packets and that packets are received in the correct order.

  5. Transmission Control Protocol - Wikipedia

    en.wikipedia.org/wiki/Transmission_Control_Protocol

    TCP uses a sliding window flow control protocol. In each TCP segment, the receiver specifies in the receive window field the amount of additionally received data (in bytes) that it is willing to buffer for the connection. The sending host can send only up to that amount of data before it must wait for an acknowledgment and receive window update ...

  6. SCTP packet structure - Wikipedia

    en.wikipedia.org/wiki/SCTP_packet_structure

    The Stream Control Transmission Protocol (SCTP) has a simpler basic packet structure than TCP. Each consists of two basic sections: The common header, which occupies the first 12 bytes. In the adjacent diagram, this header is highlighted in blue. The data chunks, which form the remaining portion of the packet.

  7. Flow control (data) - Wikipedia

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

    Sliding window flow control is a point to point protocol assuming that no other entity tries to communicate until the current data transfer is complete. The window maintained by the sender indicates which frames it can send. The sender sends all the frames in the window and waits for an acknowledgement (as opposed to acknowledging after every ...

  8. 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.

  9. Retransmission (data networks) - Wikipedia

    en.wikipedia.org/wiki/Retransmission_(data_networks)

    Retransmission, essentially identical with automatic repeat request (ARQ), is the resending of packets which have been either damaged or lost. Retransmission is one of the basic mechanisms used by protocols operating over a packet switched computer network to provide reliable communication (such as that provided by a reliable byte stream, for example TCP).
