Have you guys ever banded together to solve a few math
problems with
this network?
I would be interested in learning how to do it.
That would be LOTS of fun. I'm in!
I'm even more interested if we could do it with (or
including) PDP-11s. Many of my PDP-11s have serious floating
point hardware.

10 and 20 are way too high. The problem is that the default cost for QNA
and UNA circuits is 3 (or 4 - I don't remember). Everybody connected to
Johnny's bridge therefore sees a cost of 3 to everybody else on the bridge,
even though that connection actually requires a hop over to Sweden (psilo)
and back again. Any two machines with Johnny's bridge would never use the
Multinet connection, even if it were a direct link between the two.
Cost don't impact performance. .. ....
I guess that the "problem" here is that most people have local
machines on the same segent that is bridged.
Having a "to low" metric makes it impoissible to prefer a better path
that have serveral hops, over the bridge.....
This sounds strange but.....
Reliable - PTP link 10
Unreliable PTP link 20
Ethernet bridged 30
Would most likely render the optimal performance.
Why?
The ethernet bridge would, in my eyes be preferred to two or three reliable PTP links. The ethernet link is very fast for most people (unless they themself are on an ISP with severe limitations, in which case any other link will suffer equally), and has, with one or two exceptions proved very reliable.

Hi Bob,
In case an old version (19.28) is ok you can try the following.
I recently copied that version which compiles under 6.1 to a machine
with 8.4 and it works. As usual, if X is not available you get the
terminal version. At RULLFS:: you may find EMACS.ZIP and GNU_STARTUP.COM.
I zipped the contents of SYS$SYSDEVICE:[GNU].
In LOGIN.COM:
@SYS$COMMON:[SYS$STARTUP]GNU_STARTUP EMACS-19.28 NOLOGICALS,NOVERBOSE
which gives you
EMACS == "@SYS$SYSDEVICE:[GNU.LIB.EMACS.VMS]KEPTEDITOR EMACS"
In case something is missing, the V6.1 machine still boots :)

Of course not, but two hops via the bridge (as compared to one hop via
Multinet) does...
Bob
But 10 or 20 on SG1 for the multinet link to you would make you in control
over all of it. You could chise your bridge, my Multinet or the SG1 multinet.
I can give you login on STUPI...

Bob and I are experimenting with Multinet in TCP mode, seems fine, but
I would like to se some traffic on the link, and it's assymetric.

Would it be possible to change the metric on SG1 on TCP-0-2 to for

Actually, what hapen if we set all multinet UDP links to 20
and TCP links to 10 ? Things would then be symetric and take the most
reliable path.... or?

It's normally the running of tasks that takes memory.
The nodename server is managed by a program called SCP. To start it,
you do "SCP START".
NETINS asks me to start NNS. If I say YES, NCP START SYS says GEN is
too fragmented. If I say NO and fiddle with the pool it comes up fine.
Ah. The memory is too fragmented because NT.NNS is started before the main network stuff. Yes, changing the order is a good idea here. But it's not the installing that is the problem, but the fact that the task is actually started before the network.
