Large Cabling Project

good day to all!.

I am currently working and studying on a possiblity of a large networking project.

I have dealth with basic networking in the past, but not this complexity.

I will be needing to wire a new office building. And I am hoping to get some tips and suggestion to all.

I have two wiring diagrams at the moment, not sure which one will work best.

Please pardon my sketch.

I will be needing to run 8 to 12 switch of 48-port each.

The farthest switch could reach around 90meters - 95meters.

I am leaning on a gigabit switch from Linksys.

What specific switch will perform well? Brand? ports?

What is the best cabling method to connect all 8(or more) switch? cat5/cat6? fiber optic?

Can a single DSL line capable to supply all switch for internet connectivity?

any suggestions on the wiring?

What is the best switch that can handle large connected switches? (i.e 15-20 switches)

Hi

Both topologies you have given have a single point of failure in terms of the uplink to the DSL connection.

Although the network is not huge, its big enough to require more than one vlan in my opinion so you would need a Router capable of routing between vlans or a switch which can do basic routing.

If you look at the Cisco Enterprise Campus model on thier website and try to stick to this in terms of the topology (the Core/Distribution can be a single entity).

In terms of cabling, it will depend on the budget and how many comms cabinets/rooms you plan to have. If money is no issue you would be going Cisco for your switches right? Have a look at the differences between CAT5E/6/7 etc and decide from there. If you can afford to run Fibre then go for it but bear in mind the switches will need to be capable of doing fibre so could need additional modules and SFP's etc.

95 metres and GigabitEthernet?   You are approaching the outter fringes of what GigabitEthernet can achieve.  I doubt if you can get GigabitEthernet when your horizontal cabling along is 95 metres.  How many metres are your patch cables?

Depend how many people would use this network but personally I would use first hop redundancy protocol to asure high availiblity. As Leo said 95m is bit too much for gigaethernet. 1000Base-T should work up to 328 feet. But is only theory.

I would see it that way:

Thank you to all of your replies, all points are really appreciated, the cabling is not yet final, we may opt for fiber or limit to cat6 below(80m or less).

I/We am also thinking to separate all lines that will only used for plain network and internet-network use. is this good?

does shifting or dividing the vlans can reduce bottleneck? (from 48port to 2X24port)

how to divide a dsl connection into many as what Mr. Marcin suggested?

You need to put switches closer to the client.  Run fibre optic from the "remote end" switch back to your distribution/core.

does shifting or dividing the vlans can reduce bottleneck?

You mean a flat VLAN vs a segmented VLAN?  Segmented VLAN will win anytime because it contains local broadcast locally.  However, flat VLAN will still work but it will depend on the size your your VLAN.

If you have, say 200 machines, it's totally irrational to segment your VLAN.
