We have issues with people streaming radio stations, videos, and playlists as well as chatting on trillian, aol, msn etc. I was wondering how I would allocate only a certain amount of our bandwidth for these features so they don't eat up our resources without blocking them totally. We have Cisco routers and switches fyi.

If you know what ports the traffic is using you can implement QoS policies to determine their line speeds etc. You also use those policies prioritise genuine traffic.

It is a good idea to check availability of the QoS  functions on the specific hardware and images you are using;  sometimes QoS was limited without featuresets or required certain featuresets to be used.

It just depends on the exact software version and hardware you are using in your environment.
