It got dropped by someone; It got lost on the way (wrong detour) and will arrive later; How does the SEQ number order recover from this situation.

Web13 apr. 2024 · Because segments (or packets) travel in IP datagrams, they can be lost or delivered out of order, so the receiver uses the sequence numbers to reorder the segments. The receiver collects the data from arriving segments and reconstructs an exact copy of the stream being sent. WebIn the example above, the receiver would send an ACK segment with a cumulative ACK value of 2,000 and a SACK option header with sequence numbers 3,000 and 11,000. The sender would accordingly retransmit only the second segment with sequence numbers 2,000 to 2,999.

WebThe TCP sender sends an initial window of 3 segments. Suppose the initial value of the sender->receiver sequence number is 408 and the first 3 segments each contain 870 bytes. The delay between the sender and receiver is 7 time units, and so the first segment arrives at the receiver at t=8. As shown in the figure below, 1 of the 3 segment (s ...
