Just getting started, there are probably some easier reads out there but
that book will definitely give you the goods on TCP/IP...
Regarding your question/statement, you are accurate that the raw Ethernet
frame format has DA, SA, EtherType, Data, and FCS - to be a valid frame it
just has to be
Ethernet Version II does not have a length field, as you say, although IEEE
802.3 does. But Ethernet Version II still supports variable frame sizes. It
just makes the NIC work a little harder. The NIC listens until clocked bits
have stopped coming in and then it knows it's at the end of the
Great answer, but be careful with that raw term which to Novell people
means the Ethernet raw format, aka ETHERNET_802.3, ask novell-ether, which
is dest, src, length, immediately followed by the IPX header. The frame is
only recognizable because an IPX header starts with an XNS checksum,
3 matches
