Networking requirements

I have a simple question, on an heavy/busy network what network requirements do you guys suggest for video conferencing, email, shopping cart and images? thanks

A LOT (assuming you don't limit the p2p usage). You need figure out exactly how much bandwidth is currently being used with your video/p2p apps. I'd suggest rrdtool or mrtg to graph how much traffic is flowing through your routers. Then I'd add the bandwidth needed for the video conferencing (amount needed for 1 stream * number of users that will be using it) and add it up.

are you talking lan requirements or like internet bandwidth requirements?  Email/carts/images shouldn't require anything special, but if you are talking about streaming video through your internet connection...you could eat up a LOT of bandwidth.

It depends on the bandwidth being used...

Run it and find out what you are currently using and compair it with network cap.

Sagat,

I don't think email/carts/images would require large amounts of bandwidth.  But the design of your Video Conferencing solution should.  If you will have a only 1 Video Conferencing camera...then you want to ensure that traffic on the LAN receives priority over other traffic as well as when coming thru your WAN.  Depending on your firewall you may or may not be able to do this.

If each end users will have a Video COnferencing device...I would strongly suggest 100/1000 GB NICs for those systems.  That means your switch would need to be 1000GB compatible.

That's not really such a simple question.

That's the whole gamut of top corporate telecomputing sales and executive management, like you'd find in the penthouses of New York's Fortune 500.

How about a backbone in the basement of the 100+ story skyscraper, to start with.

For those "network requirements" you'd need to start with a consulting fee of over $100,000.00

i am reffering to both LAN and Bandwidth requirements; it is just a scenario though

You would need to do an analsys of the situation.

1. Streaming video. Size / expected cap of bandwidth

2. Network cap. of normal traffic.

Those are just 2 off the top of my head. You need a little more information sizes, cap., overhead, amount of users. Those are just to name a few.
