WebQuestion: Compare GBN, SR, and TCP (no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel) by the receiving host (Host B) and the sending host (Host A) respectively. WebTimeout is a predetermined time interval after the sender sends the packet; if the sender does not receive an acknowledgement before the timeout, it usually re-transmits the …

WebThe sender maintains a timeout clock for each of the unacknowledged frame number and retransmit that frame after timeout. Acknowledgement will be piggybacked to the sender. But when there is no traffic in the reverse direction, piggyback is impossible, a special timer will time out for the ACK, so that the ACK is sent back as an independent packet.

WebDec 31, 2024 · Suppose all 3 ACKs sent by the reciever are lost. At this time, the receiver is waiting for a packet with sequence number 3. On the sender side, the send window is filled with outstanding packets. In case of a timeout, all the outstanding packets are resent and are correctly discarded by the reciever. We all know that ACKs are not resent. WebThese techniques include the use of sequence numbers, cumulative acknowledgments, checksums, and a timeout/retransmit operation. 254 CHAPTER 3 " " ₀" " TRANSPORT LAYER 3.4.4 Selective Repeat (SR) The GBN protocol allows the sender to potentially “fill the pipeline” in Figure 3.17 with packets, thus avoiding the channel utilization ...
