Sequence and Acknowledgement Example
Each side maintains its own sequence numbers and they do not have to start at 0.
- They are in the range of 0 through 2,147,483,6478
ACK No. = Sequence number + good bytes read in the segment + 1.
Acknowledgments can be piggybacked onto transmitted segments.
Senders can time-out waiting for a response and resend the segment.
