I could use some help doing ascii art for network diagrams.  These would
be very useful for ascii versions of internet-drafts (working papers I
release as part of my research).  Here is what I've tried:


This is my basic network diagram.  Just a bunch of interconnected
routers with some sources and receivers designated.  Note that my
routers just look like spools of thread!  Ideally, they would be nice
round spheres and the interconnections would stand out better.

      R1      R2


From this basic diagram, I illustrate a sequence of events.  In this
case, the two receivers are joining a multicast group via explicit
grafts...each sends a message up into the network, and I try to
illustrate the path the messages take.  The M's stand for where R1's
message should go, the N's for R2's message.  A number followed by M or
N indicates a sequence of events...first R1's message travels the first
hop.  Then R2's etc.  You should be able to get the idea...

want:
