This past Sunday, Johnny and I spent a fair amount of time looking at circuit costs (and
performance) between SG1:: and JOCKE:: while testing his new Multinet-tunneling code. The
findings were a bit strange to say the least. At the moment, the LAN circuit costs here
are set to "4" to reflect what the VMS machines set their network interfaces to.
It seems that RSX sets costs to "3". Why are they different? Who knows!
The values are somewhat arbitrary; it doesn't really matter what scheme you use but if
you are inconsistent the routing may be surprising.
The routing spec has a suggested algorithm (100,000/line speed) which may have made sense
in the old days but for modern networks isn't terribly useful.
