ARQ in Data Link Layer

HDLC frame structure uses ______ transmission of frames.

In HDLC, ______ Fields are used to delimit a frame at both ends.

In HDLC, ______ stuffing is used to avoid confusion with data containing the flag sequence.

In HDLC, the ______ Field identifies the secondary station that sent or will receive a frame.

HDLC Operation consists of exchange of information, supervisory and unnumbered frames have three phases : initialization by either side, set mode & seq ______ transfer with flow and error control using both I & S-frames.

In HDLC, flow and error control are piggybacked on ______ frames.

Frame Check Sequence Field (FCS) is used for ______ detection.

In HDLC's Normal Response Mode, the primary station ______ the transfer.

In HDLC, ______ frames are used to solicit response from peer.

In HDLC, the ______ bit is set to 1 to indicate response to soliciting command.

HDLC protocols are used for ______ control and error control.

HDLC introduced the need for ______ link protocols to handle flow control and error control.

Data Link Control Protocols need a layer of logic above ______ to manage exchange of data over a link.

Flow Control ensures the ______ entity does not overwhelm the receiving entity.

In Stop and Wait protocol, the source waits for ______ before sending the next frame.

Sliding Windows Flow Control allows multiple ______ frames to be in transit.

If the receiver's buffer is full, it can stop the flow by not sending ______.

The transmission time and propagation time influence ______ control.

When the receiver gets a damaged frame i, it rejects frame i and the transmitter ______ frames from i.

If the transmitter times out, it sends ack with ______ bit set.

In Go Back N protocol, the whole sequence of frames is ______ from the damaged frame.

Selective Reject protocol only ______ rejected frames are retransmitted.

Receiver can ACK frames without permitting further transmission by sending a ______ Not Ready.

If the transmitter has a timeout, it will ______ the frame if no ACK is received within the timeout.

In HDLC protocol, ______ stations control the operation of the link.

Automatic Repeat Request (ARQ) is a collective name for error control mechanisms, including ______ and Wait and Go Back N.

The receiver must maintain a large enough buffer in Selective Reject protocol to ______ retransmission.

In the Sliding Window protocol, the sequence number is bounded by the size of the field (______).

The receiver gets two copies of the frame and uses ______ numbering and ACK0/ACK1 to resolve the issue.

If the ACK is damaged, the transmitter will not recognize it and will ______ the frame.
