Applications only know it made it to the socket queue, not that TCP ever sent it and got
an acknowledgment or that the remote application got the message. To do reliable communication
you need an end-to-end acknowledgment. This doesn't have to be on a per-packet basis but
on a per-transaction basis. Think of what SCP/FTP do for file transfer.
