Managed Switching Hub conunbrum 1

[tedsmith]

I am trying to find out exactly how a managed switching hub works.
I have an incoming fibre optic with video streaming sources of many remote security cameras from a large LAN that I want to feed off to 20 workstations and a local server.
The workstations only need 100mhz speed and are scattered about on up to 80metres of cable each.
I want any workstation to be able to see video streaming from the fibre optic sources but normal slow data from the local server.
I read that a managed 1ghz switch would be the best way to go for this with all computers hooked up to the one unit.
I dont want my local slow data between the local server and the local workstations not viewing video to be slowed down and hoped the video streaming would be somehow separated from the local data by the managed switch - or does it work some other way?

You may wish to get a switch that supports some form of QOS or Priority.

The simplest and dumbest standard is 802.1p, which supports 8 levels of priority, typically by port. (the hardware my have fewer levels, you only need 2)

By making traffic FROM and TO the server's port the highest priority, and FROM and TO the Fibre a lower priority, local traffic would never be held up by the camera's traffic.

All traffic for higher priorities will be sent before lower priority traffic, but there is no upper speed limit to low priority traffic, if there is no conflict.



I tried to remain child-like, all I acheived was childish.

Thanks
How do I set these settings on the switching hub?
Does the switch device come with special software that I load on a computer?

It can, I use Nortel's Java Device Manager for my Nortel Baystack 350 and 450s. Older switches may use telnet, newer ones will have a web page, so you just use a browser to set it up.
