I have a question concerning the TCP Spec RFC793
http://www.faqs.org/rfcs/rfc793.html page 37:
"If an incoming segment has a security level, or compartment, or
~~~~~~~~~~???? ~~~~~~~????
precedence which does not exactly match the level, and compartment,
~~~~~~????
and precedence requested for the connection, a reset is sent and
connection goes to the CLOSED state."
Can any high hand give me some explanation on what "security level,
compartment and precedence"
