<font size=3>Just for the record about DECNet:<br><br>
At the peak of population, I managed naming and addressing assignments
for a DECNet network with just over 8000 nodes. Local routers were mostly
Digital Equipment, some wide area used Cisco. After a major split
in the network, the remaining 3500 or so Phase IV nodes coexisted happily
with AppleTalk, IPX, and IP hosts on a Cisco backbone. My
multiprotocol workstation was an Apple Macintosh IIci. Of course, by now
the routing network is all IP based with several tens of thousands of
routes in the default-free internal network.<br><br>

Years ago, I worked on a academic network where we had a mix<br>
of IPX, DECnet, Appletalk, and IP(v4). Not all of the routers<br>
actually routed each protocol -- DECnet wasn't routable, and I
recall<br>
some routers that routed IPX, while bridging
IP...</blockquote><Snip><br>
I remember old DECNET, DDCMP, IPX and NetBios days.<br>
I used to have a couple of 19.2 kilobaud async lines, 2 arcnets and<br>
an ethernet (thinwire technology but on RG13U cables, almost yellow
wire<br>
and UHF connectors - PL-259 like CB-radio).<br><br>
DDCMP could route, IPX could and NetBios was riding on either IPX or<br>
DDCMP so it did not matter.<br>

In its best times the network was seeing some 1000 hosts. Everything<br>
was running 10 MBit ethernet. there were 9 segments and no
routers.<br><br>
I have seen you could put some 30 NetBios PCs into a single segment<br>
or more than 200 DECNET hosts if they were connected via switches
and<br>
thinwire transceivers.<br><br>
Today without thinwire or yellow cable and with switches that can do<br>
1 Gbit between switches and 100 Mbit to devices you should be able
to<br>
keep some 1000 hosts within a single switched network.<br>
