Cisco recently announced that the Cisco Networking Academy has enrolled its 1 millionth concurrent student for the first time. An example of cloud-based education delivery, the Networking Academy teaches students how to design, build, troubleshoot, and secure computer networks for increased access to career and economic opportunities — in communities all around the world.
There is a country whose east and west coasts border on major oceans. Its major cities dot its coastline, while its internal areas, while populated, could accurately be described as “flyover” zones. It takes about six hours to fly coast-to-coast.
Its government is making the single largest infrastructure investment in the country’s history, investing $43 billion over eight years in order to connect 90+ percent of all its homes, schools and workplaces with broadband services over fiber-optic cable with speeds up to 100 megabits per second, 100 times faster than those currently used by many households and businesses.
Which forward-looking nation committed to this bold goal?
As companies grow large, we have a natural human tendency to declare them incapable of getting out of their own way. We see them as slow, inefficient and plodding dinosaurs surrounded by fleet-of-foot small companies that are so much more capable of getting things done — because of their apparent smallness.
And while there are certainly large companies that suffer from bigness, there are also quite a few that demonstrate amazingness, if you’ll allow me to make up a word (for agility, beyond compare). One of them? The mighty, much criticized Bell System, created in the transition zone between the 19th and 20th centuries.
It began as a way to link academic and research institutions throughout the United States, so that they could more easily communicate and collaborate on projects. In the beginning, it was limited to a small number of entities, all of whom thrived on the cutting edge of networking technology.
If that sounds like the early days of the Internet, it is. But it’s also an equally apt description of National LambdaRail (NLR), a 12,000-mile, $70 million optical network established in 2003. It uses 10-gigabit (Gb) transponders (with 40Gb and 100Gb in the roadmap) that allows bandwidth on demand for its academic and research members, now numbering more than 280.
The name comes from the term lambda networking, which uses multiple optical wavelengths to provide independent communications channels along a strand of fiber optic cable.
Networks are an essential part of business, education, government, and home communications. Many residential, business, and mobile IP networking trends are being driven largely by a combination of video, social networking and advanced online collaboration applications — when described together, it’s called “visual networking.”
The Cisco Visual Networking Index (VNI) is the company’s ongoing effort to forecast and analyze the growth and use of IP networks worldwide. Earlier this month, we announced the latest report, the Cisco Visual Networking Index Global Mobile Data Traffic Forecast, 2010-2015. The following is a thought-provoking summary of the key findings — see how we visualize the future of the Mobile Internet.
