How would you setup 90 computer LAN?

90 seats + servers. We're probably going to use 1Gt main network/network skeleton/backbone network (Im not sure of the term in english) and share it in segments to the tables (Using 4x 24 slot switches). Any better suggestions?

Although not sure how to setup the router (Using 1 server as router).

The 4x24 switches you pick up need a Gbit uplink port.

Why do you think you need Gbit though? If it's gaming only, 100mbps should be fine for 90 seats assuming everything is switched.

There's no need to have Gbit. Perhaps you should ask cheater and old_skul or one of the other UVALAN staff members to see what they did.

Wrong iNVAR. People held 90 seated LAN here with 100Mb line and it was a lagfest. We try not to fuck it up :)

Ofc maybe they had really sucky setup. But if we can get 4x24 Switches for free, why not? :p Faster = Better

But yah, could ask Cheater :)

Not wrong at all. We have lans with 100+ all the time with only a 10mb lan link and it works flawlessly.

The main thing you need to look at is why do you need a router? Do you do any kind of routing from your lan to another network such as the internet? if so then use something that's easy to configure and easy to fix when it breaks. Don't try to get all fancy and technogeeky on it, do what is needed, not what the cool thing at work is.

For the network, make sure of 3 things. The switches are fabricated and not clustered. Make sure the computers have their settings on auto or forced full/100 (not half/100 or 10/full). Cables, cables, cables... gotta make sure there aren't any bad ones or it can and typically will break the entire switch it's plugged in to.

On the switches, you will need one to act as the "core" switch that all the others plug into, this can simply be a 4 or 5 port gigabit or 100mb switch that the uplink ports of all the others plug into, or the better way is to have each uplink port go to the next switch (what kind are you using anyway?).

There are dozens of ways to do it, and several of them will work fine, but several will kill your network too.

Oh yeah, and don't have a switch with a cable looping back to itself :p happened at UVA heheh

I found one of those at the house yesterday iNVAR. :p

Ok i might've used a wrong term. My overall english is quite fluent but my "Business" english and Computer englishh is far from flawless.

1st: There will be Line out (internet connection). This is because, well, finns irc ALOT. And it can be guaranteed that if there is no line out, nobody will come ;) And stuff like web-based games (Planetarion stylish), Emails and such are wanted.

2nd: This LAN will take place at our school, so there already is network and line out. But we cannot use the normal network because we a) won't get access b) It's too slow. It's not planned for gaming, so if 25 people (1 class) plays CS, the whole network works on modem speed.

Here's how my friend thought about it (Note, neither of us are pros and haven't held LAN's before):

The core network (be it 100Mb or 1Gb) will have Switches and Game servers attached to it. The switches (4) allocate the core network line to tables (4 tables, 16 - 24 computers each + admin table.). There will be one server that works as _Router_ for the Line Out and "hides" our network from school network (not exactly sure what he meant by that. I don't basically work with the network so..). This server will also handle the overall network (Probably will be DHCP server, or then we use manual IP's, not sure yet).

Does this clear anything up? Like i said, im nowhere near pro with networks, so sorry if anything sounds very unlogical. :)

Games don't use up much bandwidth at all. Again, a 100mbit switched network should NOT lag out at all if set up properly and it's used for gaming and IRC.

Well our school network is not setuped for gaming like i said ;) But we won't/can't use it. If we get switches for 1Gbit, we use 1Gbit. If not, we use 100Mbit. Simple as that. Not paying for sponsors anyways.
