Hello guys.

Imagine an university has 100 mbps as its network speed. How it divides its speed among students and employees for video streaming, web browsing etc both in a) wired and b) wireless fashion?

Thanks

Students have better things to do than homework. :)

There are many ways to control bandwidth, starting with no control at all and just letting users take what they can get. Read about QoS and bandwidth management. Also, there is an additional issue with wireless beyond the ISP maximum throughput, and that is the available bandwidth on wireless depending on the wireless type, equipment used, etc. Certain types of use may also be blocked, the real connection hogs like torrents.

THIS is an older Cisco white paper on G wireless, but the concepts still apply and you may find updated information for N and AC if you look. And it is probably a better source to cite than Wiki. lol

I am new to networking so It is hard for me to imagine such issues...if 100 mbps is the network speed then say for example one student getting 80 mbps then that means others will get 20 mbps right? Or if one student get 1 mbps 100 will get 1 mbps each, so that will take up 100 mbps? Sorry if i sound noob

The university has far more bandwidth in their connections to the Internet than 100Mbps, but they are managed so that users can all coexist. The worst place will be dorms where every yahoo wants to stream video and run torrent servers.

In that case one user can cause issues for all others on his subnet -- remember that not everyone is on the same network, it will be divided into multiple subnets and there has to be significant control in place. Heck, even my house has a backup DSL for the cable 70Mbps connection and I control user bandwidth.

In a very simple network, like one 10Mbps connection and a single 2.4GHz wireless radio at a house, one user can easily use all available bandwidth and create a situation where he and all other users have very poor connections that are slow and frequently drop users. We get those kind of questions all the time on the wireless networking forum.
