TCP Segment Order
•Most TCP implementations will accept out-of-order segments (if there is room in the buffer).
•Once the missing segments arrive, a single ACK can be sent for the whole thing.
•Remember: IP delivers TCP segments, and IP is not reliable - IP datagrams can be lost or arrive out of order.
