Karn) Newsgroups: comp.protocols.tcp-ip Subject: large corporate networks Message-ID: <8807052226.AA10904@thumper.bellcore.com> Date: 5 Jul 88 22:26:09 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 18 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
