I was teaching a Quality of Service (QoS) course at Interface a few weeks back. One of my students asked an interesting question: Is it possible to use QoS to throttle bandwidth for just a few, a-typical "bandwidth hog" websites using only Cisco gear... You bet it is! ...and what a cool idea! We worked through the configuration on the whiteboard, and Mike Storm (a fellow instructor & friend) documented the process...here's what we came up with:
For the sake of all that is sacred....save us from the bandwidth thieves! YouTube, Google Video, MySpace....and others. All of them are to thank for our latest level of Internet bandwidth saturation. If it bothers you like it does me, why not do something about it. Save the Internet bandwidth for your business!! On a Cisco router, it is easy to recognize and limit this type of traffic by using Cisco Quality of Service, specifically NBAR and traffic policing components.
