I've gotten about 20 requests for a SPUDNET map since the gateway at
ucla-cs opened up, and I noticed an address request in net.net-people the
other day, so I'm posting an abbreviated guide to SPUDNET here (Most of
this is drawn from the SPUDNET Protocol Guide SXL-14).  Further questions
can be directed to me or to the SPUDNET moderator, Douglas Trainor
(trainor!ucla-cs).

These are the current major SPUDNET sites (as of 4/85):

Name            Poll            Notes

ucla-cs         Demand          Gateway to USENET.
dddrcf          Daily
cldh            Daily           Abandoned Bell switching center (?)
ihop            Morning
berke           Morning         Limited traffic allowed.
russet          Demand          SPUDNET administration site, also has
				limited gate to USENET through vvlxtr.
bbring          Twice daily     Ring of Apple-II bboards.
bigmac          Daily           Goldman's.
opark.6         ??              Been down lately.
lexhax          Midnight        Timekeeper for SPUDNET.
idaho           Demand          Mail only.
lthouse         Daily

These are the secondary sites.  Unless marked otherwise they are polled
once a day on an if demand basis by one or more of the major sites:

bbvxen  hslpc   klingon shltz   croesus*
lnwdl   ppvax   qbert   rehier  bigman
yloh    elbib   kyle    psato   buranim**

Polling protocol is as given is SXL-7.  A program implementing this in
xlisp was posted to net.sources several months ago.  A C version is
under development at aqfc@lexhax.spud.  Pathing is done at each site
according to an algorithm that guarantees least time in transit between
major sites (but does not guarantee quickest travel to secondary sites).
A description and implementation of this algorithm was presented at
the Second Symposium on Network Traffic Analysis (Terre Haute, 1983) and
is available from the author at edmond@ianian.spud.

If there is sufficient interest perhaps we should start up net.spud, which
I'll arrange to port to SPUDNET.
