Mobile applications – 3G+ is 22% by 2010 (Mobile goes hi speed)
Consumer Internet Traffic 2006–2012 This category encompasses any IP traffic that crosses the Internet and is not confined to a single service provider’s network. Peer-to-peer (P2P) traffic, still the largest share of Internet traffic today, will decrease as a percentage of overall Internet traffic. Internet video streaming and downloads are beginning to take a larger share of bandwidth, and will grow to nearly 50 percent of all consumer Internet traffic in 2012.
Fortunately the web stack has evolved. OSS Technologies such as Varnish (
high-performance HTTP accelerator… reverse proxy), gearman (open source message queuing system that makes it easy to do distributed job processing using multiple languages… function dispatcher) and hadoop (distributed computing platform)
