At a former work place (was an e-commerce web development company) had ~500 end users comfortably sharing a T1 (less spam :). Where I currently work, I'd estimate that ~300-400 comfortably share a T1 line. The work is not web related, email traffic through the line is appr 10,000 a day (5,000 spam). I'd have to ask the network guys how much traffic there actually is to. Set up MRTG to monitor bandwidth utilized from day one. MRTG is a free bandwidth montioring tool that helps with utilization trends (runs on Linux and Windows with perl).
Couple things to incorporate. Underestimate usage if posible. Set email attachment limits NOW (5 megs is reasonable) if you don't already have them. Also, if you don't have them, set attachment type blocks as well. This will avoid email viruses. I put the blocks on down to a server level, that way, if a client gets infected, he bombs himself and I don't get stupid questions (I can email an exe to Bob at work but not to home, etc). If it's executable, then block it, they can zip it up otherwise and if they don't know how, they can learn. Consider also a web caching server, many queries will be to the same sites as people find the latest 'neat' site and send others to it. I realize you didn't ask about email, etc, but realize, once the pipe is out there, people will use it in unexpected ways. If they are not going to be getting pop mail through it, then make sure you block it at the firewall from day one! In fact, if it's JUST for web, open up 80, 443 and only what you need, otherwise, getting it locked down once it opens, will be almost imposible. Have fun. -sp Ref> http://www.7-zip.org/ http://people.ee.ethz.ch/~oetiker/webtools/mrtg/index-2.html http://www.swinc.com/resource/exch_faq_appxj.htm http://www.squid-cache.org/ -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Craig Caughlin Sent: Saturday, August 30, 2003 4:05 PM To: LEAF (LEAF) Subject: RE: [leaf-user] OT - How many users will a T1 line service?

That highly depends upon he expected usage. Are they just going to browse the web and pop email or are they going to do heavy downloading and/or audio streaming?
