It definitely had subnet routing, and as I recall, the KL10's and other
machines with front end I/O processors generally used chaosnet routing
between the host itself and the rest of the network. i.e. the I/O
processor was on one subnet, the host on a second subnet and the rest of
the "LAN" was on the other side of the I/O processor. My recollection is
that unlike an IP router, a Chaosnet node had only one address, and
routing tables determined which device to send the data on.
And LCS definitely had multiple coax cable runs with each run a subnet
with routing between. But with a maximum of 256 subnets, routing was
much simpler.
I wonder how much benefit is available from using network switches
rather than collision detection and retransmit, though the virtual token
was supposed to reduce collisions somewhat.
