Many are concerned about cell phone networks getting overwhelmed on Tuesday during the U.S. presidential inauguration.
Cell phone networks are built to be oversubscribed, using statistical analysis to bet against a certain of users flooding a network all at the same time. While it's never been a fool-proof strategy, it's worked reasonably well until recently when smartphones and bandwidth-intensive applications have moved to mobile devices.
But cell networks aren't the only networks starting to get overwhelmed. Cisco Systems says that in 2012, Internet video traffic alone will be 400 times the traffic carried by the U.S. Internet backbone in 2000. Video-on-demand, IPTV, peer-to-peer video, and Internet video are forecast to account for nearly 90 percent of all consumer IP traffic in 2012.
"Cisco VNI projections indicate that IP traffic will increase at a combined annual growth rate (CAGR) of 46 percent from 2007 to 2012, nearly doubling every two years. This will result in an annual bandwidth demand on the world's IP networks of approximately 522 exabytes2, or more than half a zettabyte."
With this and the continued growth of converged networks within enterprise environments, the thought of the simple data network is no more. Networks have become highly complex and distributed, tasking companies with the need to scale to monitor and analyze all aspects of the voice, video and IPTV.
The network that has become overwhelmed in 2008 will become incredibly burdened in 2009 and beyond if companies do not manage their bandwidth.… Read more
