It's inevitable whenever there's a big sports event, that you see articles in news journals talking about the spike in Internet usage from that event, due to everyone watching the live video streaming of it over the Internet. Net usage goes up, and slows everyone else down. The important question for the IT administrator though, is did that sporting event cause your local network to slow down as well, and did it eat up all your bandwidth to the Internet, making it impossible for your workers to get anything done that day?
The next big test of networks is coming soon. The Beijing Olympics is just around the corner set to start on August 8, 2008. CCTV has already announced intentions to broadcast videos of the Olympics available for download from their web site. CCTV is already planning on using a e-CDN (Content Delivery Network) to help offload their web servers. But will office workers watching the Olympics crush the typical organization's web link and internal LAN traffic? The answer is no, if you've got the right web proxy in place.
As long as you're using a proxy to secure your access to web traffic, and your web proxy supports caching of video streams, you should be able to offload the web usage by video watchers. If you have web proxies at your remote offices sharing the same link to the Internet as your main HQ, you'll also be offloading your LAN traffic. The other answer of course is to block video traffic entirely using the proxy, but that's a corporate IT and HR decision. And if it's one you decide to make, it'll be your proxy that does the blocking for you again.
