We do have a uniform network in our main area, although not big (some
It consists of a 100Mhz backbone (actually 2 100 backbones right now
because of switching to a unregistered network and one extra 10Mhz in
our main area, 10Mhz in the rest) with all large machines/servers with
100 Mhz network cards but the rest with 10Mhz connections to switchboxes
that have typically 24 10mhz connectors (10baseT) and one 100mhz connector
to the backbone.
These are all 3Com (the hubs and switches, our routers are Ciscos) and can
be controlled with appropriate software from a windows/unix machine.
Switchboxes can be controlled as groups or one switchbox can be split up
into groups with various access limitations, giving you the ability to
design a kind of network clusters within the uniform network.
Although I have some reservations about this kind of setup, the
software used to manage the hubs and switchboxes gives great control and
overview over the network, Including a database of the machines on the
net, making it usually easy to spot troublesome machines and analyze packets.
