This may be a duplicate posting, my apologies if it is. How would you expect a MPA receiver to handle an out of order TCP segment with markers disabled and CRC off? Does it just buffer it until the gap is filled? Also, if CRCs are enabled and we are processing an out of order PDU without markers, what is the behavioral expectation of a failed CRC check? A matched CRC would be sufficient to determine FPDU alignment, but a failed CRC appears only to say that you may not have FPDU alignment. That is, if I created a test that produced a gap in the TCP sequence and then sent an unaligned FPDU within a TCP segment, followed by the missing information I would expect the receiver to: (1) Not drop the connection, (2) Advance the ACK through the unaligned segment when the missing information was sent. Is this the correct understanding? Barry Reinhold Lamprey Networks [email protected] (603) 868-8411
