network improvements ?

[fran19422]

Hello, I have put together this network as part of a project.

I am trying to think of ways of improving the network design.

My first idea was to use CAT6 or optical fibre on the trunk links in Main Building LAN between switches (wihch is comprised of VLANS).

Does anyone have any suggestions as to what else could be improved on this network topology, based on what you can see here ?

Thanks for any ideas.

"Improve" is subjective, and depends on what the business and technical gaps include.  Just some initial thoughts on the basic design:

1. Does it appear to you that any one device seems to be servicing a lot of the network's traffic?

2. Are there any major single points of failure?  Depending on the nature of the network and applications, it may be okay if a single user, or maybe even a closet switch, is down for a short period.  But looking over your design, do you see any single points (devices) for which a failure could cause outages across extended portions of the network or the entire network?
