I am writing a paper on our practical experiences in managing Bellcore's
internal computer network. It now consists of several dozen Ethernets
interconnected by DEC Lan Bridges, Vitalink Translans, point-to-point T1
interlocation links multiplexed on dedicated DS-3 fiber, and a few IP
gateways. It now serves roughly 1,000 hosts, almost all of which speak
TCP/IP and related protocols.

I believe this to be one of the largest networks of its type, and I
would like to compare it to other corporate computer networks. Can
anyone give me a feel for what other large companies have in the way of
internal computer networks? I'd interested primarily in dedicated, high
speed (>= 56 kbps) networks with 500 hosts or more.  Slow speed "data
PBXes" (e.g., Datakit and similar toys) designed primarily for terminal
switching don't count.

Thanks,

Phil Karn
