Hierarchical model design implementation
« on: October 27, 2015, 01:09:07 PM »
Hi

I am designing a network for a project. There is a HQ and a branch office.We were recommended to use the hierarchical model.The HQ is spilt over 3 floors with 280 end users with wifi for 30 quests. The branch has 832 end users spilt over 3 floors as well. The router in the HQ will be connected to each distribution switch in the branch.I have enclosed my HQ design.The Branch will be similar to floor 2/3 of the HQ just with more access switches and end users on each floor. Some feedback would be much appreciated

OK, you mentioned a need for 280 users... how many per floor? Do they need wired or wireless or both? If both, how many wired/wireless? Do you need to support voice VLANs or only data? Is there a need for Internet access?

Why do you have servers directly connected to the router? That seems... odd...

those poor little 3560's  connected to the router will surely get overwhelmed with user traffic with the other floors traffic running through them.

OH SNAP THAT WOULD BE BAD

Also moved the topic to a better part of the forum...

Now that I look at it more closely, there are quite a few ports that are down/down... those servers are going to be very, very secure.

There would be 46 on floor one and 117 per floor on 2/3(Planning on using 48 port switches on the access layer).
They have to be wired connections.
I used VLSM to separate traffic for data and voice. Would you recommend putting the servers on the distribution switches.
On connecting the distribution switches on Floor 1 to 2/3, I was going to connect each of them switches to each other so if one went down the other would kick in then .

On the ports being down. It does not have to implemented, just a logical design of the network.

I have enclosed my logical design for the Branch Office for some further feedback.

Servers should be on their own access switch, there will be lots of traffic going to them.

There's still an issue of needing redundant links between floors. You have a mesh setup on a floor, but only one link between floors. There should be two lines from 1 to 2, 1 to 3, and 2 to 3.

Floor one to floor three connections still needed.

Think this is close enough to my finished design now.
