[K12OSN] another bandwidth question

[Santiago, Nicholas]

My pipe is actually only a cable modem (800k) and it serves our purposes
well for about 70 concurrent users across 150 workstations. 

We use a Squid/DansGuardian setup on a Mitel Networks SME Server and it
works great. Everyone can access the Internet and e-mail nice and quick.

Subject: [K12OSN] another bandwidth question 


I'm setting up some k12ltsp boxes in a school. I'm a university professor
who's offering free computers and at least some free support. (I still feel
a little like I'm saying "I'm from the Government and I'm here to 
help.") The tech guy, who has a reputation for not being very helpful, has
been fairly accommodating (I'd be suspicious of someone putting stuff on my
network too). 

His plan is to light up one network port per classroom. No problem, I 
say, the server (I'm planning to use the teacher workstations as 
servers for about 5 thin-clients) will use the only connection & all the 
other computers will still be able to surf the web even though they're not 
on the school's network. "I'll not have it" is the reply. His concern is 
that if people are actually using the Internet the T1 will get saturated. 

I've already considered things like Squid & doing bandwidth limiting and
such & will propose those "solutions" when the time comes. (I suggested a
proxy server to which he said he was using NAT, so it's not clear that he
understands a caching proxy server.) My question is, "how many users will a
T1 typically support?" Do many schools have a fatter pipe than a T1?
