Switching bandwidth ratio back to core

I am evalulating a hospital LAN which has 3 access switches (144 ports) connected to each other with fiber and then collapse on a single fiber run back to the core. I have calculated a 14 to 1 bandwith ratio. 14Gb access ports to 1 Gb fiber uplink port. What is acceptable? The users are traveling back to the core for all applications and (there are anywhere from 3 to 5 wireless AP's connected to the access switches).

Thanks,

Steve

Hi Steve,

The answer, as with most design questions is "It depends." The area of focus should be the link with the smallest bandwidth. If you are not overrunning the most oversubscribed link during peak periods, then yes, it is acceptable. Of course, you'll want to factor any expected or planned growth into that.

HTH,

Bobby
