Well.... IP has only three (source address, destination address & protocol) TCP (a protocol on IP) also has: source port & destination port and a whole buch of state UDP (another protocol on IP) also has: source port & destination port ESP (IPSEC tunnel) has no concept of ports ICMP (has no concept of ports) next to ports TCP also has state info regarding the connection, ICMP has type & subtype codes, IPSEC has tunnel identifiers, etc. > > Anyway, isn't radius UDP? :-) UDP sockets don't have to care > what the remote address > and port are, but they still maintain an address and port of > their own...
