Does TCP have a one-to-one responsibility to the ULP so the local-ULP knows what packets the remote-TCP has accepted? On a stream socket I can: 1) Establish a connection to a remote host 2) Physically DISCONECT the NAU from the ethernet 3) Issue n TCP writes and receive n GOOD return status 4) On the n+1 write or close I (may) get an error This may mean the n-10,n-11,n-12 reached their destination but n-1,n-2 didn't...or any other combination.I have no way of knowing.Can someone please explain where the "reliable communication" is? Thanks , Jeff Busma JDB@JPL-VLSI.ARPA
