Network toplogy for smaller company
« on: July 08, 2013, 02:30:05 AM »
Hello!

I wonder if somebody could explain to me how the network topology could look for a smaller company with around 20-30 employees. Each of them with their own offices. Which type of cable is preferable to use between Switches and wall jacks and between switches and servers? Is it preferable to draw cables from one switch to all offices and in that case which cable is best? Or is it preferable to set up perhaps 3 more switches each of them connected to 1/3rd of the offices? And which hardware could be the best to connect to ISPN? ADSL and then a firewall and then a switch connecting to the rest of the network?

Grateful for all help!

All comes down to your budget and when you want to stop adding zeros.  :)

for cabling, you can't go wrong with Cat6.  Cat6 has come down in price allot and will allow you to do 10,100,1000, and 10Ge.  and you can do PoE no problem.  You would use that for your work stations and severs.

As for design.  Hub and spoke, or a star design will be good for your office.  Like you said, deploying 2 or 3 switches throughout the office could be less expensive than drawing 50 cables all to one spot.   

As your office is somewhat smaller, I would not spend allot of money on expensive routers. For the core, I would use an enterprise grade firewall that would also double as your core router.  Something like a PaloAlto 500 or 2000.  From there I would collapse all edge switches directly into your firewall on either single links or LACP.

Thanks for helping...

I been thinking something like this:

A router/firewall connecting to ISPN.

The Router/firewall connected to a multilayer switch.

MUltilayer switch connected to each server individually.

The same Multilayer switch connected to 3 end switches.

The 3 end switches each are connecting to 1/3rd of the workstations and each of them has a network printer connected to them.

How does this sound?

The thing is that i want the cables to go trough the wall to each office through a wall jack.
So where should i keep the endswitches and which cable should i use for each connection? should i use cat6 throughout the whole topology?

Here is a simplified image of how i mean. Where should the switch be kept so on? Between the switches and the workstations there should be the wall jacks that is separating one cable from the other. (Not like the picture)

Grateful for all help i can get.

Yes, sounds good. It appears you have thought this out.

as for your last series of questions. I can't tell you where you should put your switches without seeing your floor plan, or knowing your budget.  I would recommending engaging a local cabling company. 

have you thought about going wireless for your users, and wired for your servers and printers?  Motorola and I believe Aruba both have enterprise grade controlerless Fat APs.   Just a thought, might be cheaper than running new Cat6, punch down panels, patch panels, cable management.

Okey thank you so much for your answer and your time, i appreciate it.
I have thought of wireless but i dont really trust it, in a security point of view.

Anyway, i am thinking of skipping the switches and just run cat 6 cables from the multipoint switch to the wall jacks. And then from the wall jacks i will run cat 5 cables to the workstation.

Star topology is good for smaller companies, it is little bit expensive than for instance ring network but it's easier to maintain and the bandwidth is higher.
Thanks,
