[net.general] USENET topology

dyer (06/07/82)

Is there any way to discover the topology of USENET; i.e., what's
connected to what?

My specific need is to mail to someone who is connected through "mhuxm",
a Bell Labs, Murray Hill machine.  But, I would like to not have to ask
these questions at all, or at least infrequently.  The ARPAnet keeps an
up-to-date (reasonably) map of what's where (and connectivity isn't even
needed by users!).  Is there anything comparable; any tool; anything at all
available?

First, to answer dyer's question: a path from wivax to mhuxm is

     wivax.decvax.harpo.eagle.mhuxt.mhuxa.mhuxh.mhuxm

This is the way the net routes it.  According to the net map I have
(explained below), this is about the 'shortest' path.

I was given a copy of a 'USENET Logical Map' dated Feb 1, 1982 by
Bill and Karen Shannon.  I was told that the folks at Berkeley keep
it up to date.  How about it Berkeley?????  How do we get it??

(Apologies if this has already been answered; I'm behind on net.general!)

Me again.  I just re-read my article and want to clarify that the Shannon's
did not give me the netmap; they are the 'authors' of said network map.
