The data won't be identical for a number of reasons:
- it's not possible to guarantee that both sides to see identical
packets especially over longer horizon spanning hardware and software
failures
- even if both sides see the same traffic after retrasmission for a
shorter period, the order of arrival may change the operation, e.g. if
you use NAT with the port number assigned sequentially wrt the order of
arrival.
- arp issues
