Obviously the subject line is self-evidently true. However... every time 
I hear Rocky Sharpe sing "Return to Sender", I inexplicably find myself 
thinking about ICMP, the Internet Control Message Protocol. (??!)

   I gave a message to my local gateway,
   He forwarded it to the next hop.
   But 84 milliseconds later,
   It came right back to me.

   She wrote upon it:
   ICMP destination unreachable.
   No such network.
   No such protocol.

Perhaps I should seek professional help...

(But do I need a therapist or a lyricist? :-P )

You need a network professional. 84 ms as round trip for local gateway
is far too long. That would be a network therapist.

LOL, I concur. :)

Who said it was returned by the /local/ gateway? It could be returned by 
any node along the route.

First line of the lyrics:

   I gave a message to my local gateway,

That's where I got it from, though it seems that actually the reply is 
coming from the next hop.

Still, 84 ms is kinda slow for a single hop away.  I'd be talking to the 
ISP. :)

  Theoretically the local gateway could be at the other side of the
Atlantic (although I assume that this would be highly difficult to
set up in practice).

Depends on the networking technology in use.

I've done work with MMV statellite connections, and IIRC, the satellite 
(in geostationary orbit) was the gateway in at least one test case.

I say again: ICMP replies can come from /any/ hop along the route, not 
just the first or second hop.

Exhibit A: traceroute.

Also... At one point we had the misfortune to use a satellite-based 
Internet connection. The /bandwidth/ was fine, but latency was about 200 
ms to ping Google. They had a big expensive HTTP proxy cache on the 
local end to try to hide the latency - which /obviously/ had absolutely 
no effect on the huge array of non-HTTP services we need to run... But 
hey, what do you expect if you try to use a residential broadband 
service set up by three blokes in a van when what you actually need is 
an enterprise-class connection?
