  • Design help for approx 100 client network

    4 rooms with 20 Windows XP pro PCS each
    4 x Laser printers
    Wireless available for laptops

    At the moment i just want internet connectivity i can add a server at a later time.

    So i guess for the backbone i am looking at some kind of cisco router.

    Now i think i will either need a subnet for each room or have each room on it's own VLAN?

    So what equpiment do i need.

    The key thing must be QOS so that each room, has approx 1/4 of the incoming bandwidth available to them.

    Do i do the QOS on the router or will i need some kind of managed layer 3 switch?

    To me it seems as simple as just going,

    router --->some kind of "backbne switch" ---> 4 more switchs ---> pcs?

    anyone give me some help?

    Where do you want to use QOS for and why making harder then it needs to be?

      I am no expert as you can see but i assumed QOS was used to allow you to distribute the bandwidth across each PC or each LAN. For example if a user is downloading and hogging all the bandwidth then nobody else can use any.

      I believe you can also use ISA to do this but i would need a server running for this, but i thought a dedicated hardware device, router/managed switch or firewall would be better to shape the bandwidth

      So i was thinking now

      router ---> firewall --> backbone switch -----> 4 x 24 port switches ---> PCs

      I could add a server to the backbone switch later on and make a domain out of it.

      But i have never done anything like this before so,

      a) Am i setting this up right
      b) What equipment for a lower end budget should i use

        How much bandwidth do you have as your Internet feed?

          I think we are talking about 1 x 50megs line of 2 x 20 meg adsl lines. BT business lines, if you don't know BT then a business line if not that much different from a standard line, apparenlty much consistent nd better tech suport etc.

            Why not just put in a Router, doesn't need to be Cisco, Put a switch in each room and connect the switch to the router.

            No VLAN's needed.

            QOS won't do bandwidth shaping the way you want it, well at least i don't think it can (runs away to check up on it). For that you'd need something dedicated.

            Why your worrying on a 50MB line i don't know lol.

              As @Dumber said, you make it harder then it supposed to be.
              80+ PC in a subnet should be just fine; split them in multiple VLANs only when you have a strong reason.
              Buy a stack of Layer 2 Switches that accommodate the need of ports, maybe one of the switches should have some PoE capabilities to supply power to APs.
              Don't buy a super router just to make a NAT, you can use a Linux box for this specific requirement (IPCop, SmoothWall etc etc). A Linux distribution as I mentioned will demand less networking knowledge.
              One of primary goals, when you design a network, is to keep it simple as possible.
