FWIW, I think the "flapping" is a Multinet problem. I have no problems
with simh and DECnet connections over the local Ethernet.
Not surprising. Multinet is a design error. With enough effort it can be made to work to
some extent, but it's by far the least desirable of all your communication
possibilities.
Multinet over UDP is especially evil. Multinet over TCP isn't quite as bad, so if you
must use Multinet, be sure to use the TCP flavor.
However, anything else is better. GRE and Johnny's bridge software are two good
options. Another one, if you use SIMH, is to use a DDCMP connection. All these options
are correctly designed and should work well. If the network connection is lossy, DDCMP is
probably the best option.
