I guess..
down there some line code <ethernet mostly for ethereal>
all the mumbo jumbo B8ZS or whatver becomes something on the NIC
that new something has ether headers.
ether headers has a demux saying upper layer IP
that IP has a demux  in it called something a protocol type
that protocol type if icmp has icmp packet types

if ip proto type=udp/tcp then udp/tcp has a demux called ports

to me it also seems like any type of basic code flow/protocol can be written
as a combo of case structures and </>/=/!= operators...as a person I really
admire for his simplistic and logical thinking  put this stuff here:
