which reminds me....
Mr. ENGINEER: (yelling and hitting the send button repeatedly) 'ELLO
NOC!!!!! Testing! Testing! Testing! Testing! This is your nine o'clock
(Takes RFC 791 out of the binder and thumps it on the counter. Throws it up
in the air and watches it plummet to the floor.)
Mr. ENGINEER: Now that's what I call a dead protocol.
NETWORK OPERATOR FROM HELL: No, no.....No, 'e's truncated!
Mr. ENGINEER: TRUNCATED!?
NOFH: Yeah! You truncated him, just as he was bein' refactored!
Datagrams truncate easily, major.
Mr. ENGINEER: Um...now look...now look, mate, I've definitely 'ad
enough of this. That packet is definitely deceased, and when I deployed
it not 'alf an hour ago, you assured me that its total lack of
throughput was due to it bein' tired and shagged out following a
NOFH: Well, he's...he's, ah...probably pining for the big iron.
Mr. ENGINEER: PININ' for the BIG IRON?!?!?!? What kind of talk is
that?, look, why did he fall flat on his back the moment I got 'im
through the router?
NOFH: The 4-byte prefers keepin' on it's back! Remarkable protocol,
id'nit, squire? Lovely octets!
Mr. ENGINEER: Look, I took the liberty of examining that packet when I
dispatched it, and I discovered the only reason that it had been
sitting in its queue in the first place was that it had been SWAPPED
NOFH: Well, o'course it was swapped there! If I hadn't swapped that
packet, it would have nuzzled up to that DMZ, bent it apart with its
handshake, and VOOM! Feeweeweewee!
Mr. ENGINEER: "VOOM"?!? Mate, this packet wouldn't "voom" if you put
four million hop counts on it! 'E's bleedin' demised!
NOFH: No no! 'E's pining!
Mr. ENGINEER: 'E's not pinin'! 'E's passed on! This packet is no more!
He has ceased to be! 'E's expired and gone to meet 'is archive! 'E's a
null set! Bereft of destination, 'e rests in /dev/null! If you hadn't
swapped 'im to the top of the queue 'e'd be pushing off the stack! 'Is
traceroutes are now 'istory! 'E's off the wire! 'E's kicked the bit
bucket, 'e's shuffled off the interwebs, run 'init 0' and joined the
bleedin' choir deprecated!! THIS IS AN EX-PACKET!!

swallows a v4 datagram does that count as packet loss or tunneling?

difference between African and European avian carriers, and we know what happens if that
question is asked at the wrong time.
