4 The TCP segments in the tcp-ethereal-trace-1 trace file are all less that 1460 bytes. This is because the
computer on which the trace was gathered has an Ethernet card that limits the length of the maximum IP
packet to 1500 bytes (40 bytes of TCP/IP header data and 1460 bytes of TCP payload). This 1500 byte
value is the standard maximum length allowed by Ethernet. If your trace indicates a TCP length greater
than 1500 bytes, and your computer is using an Ethernet connection, then Wireshark is reporting the wrong
TCP segment length; it will likely also show only one large TCP segment rather than multiple smaller
segments. Your computer is indeed probably sending multiple smaller segments, as indicated by the ACKs
it receives. This inconsistency in reported segment lengths is due to the interaction between the Ethernet
driver and the Wireshark software. We recommend that if you have this inconsistency, that you perform
this lab using the provided trace file.
