Summary:The new SDN prototype, developed as part of the U.S. Government’s DARPA CORONET program, is basically a powerful resource management system that can coordinate data flow and hand out more bandwidth when needed.
Summary:Average mobile data use in North America nearly doubled in 2013 to 1.38 GBs a month leading the world. The U.S. isn’t the biggest data hog — that would be Japan — but LTE is driving consumption.
Users of flagship smartphones such as Apple’s iPhone 5s and Samsung’s Galaxy S4 are continuing to suck down more data than their tablet-wielding counterparts, according to a large-scale survey of mobile data consumption in 2013 conducted by JDSU (which last year bought mobile data analytics company Arieso, the company that previously ran the annual survey).
For the 64 percent of Americans whose internet service provider imposes a broadband cap, and for those lucky enough to have a meter, I have some bad news. The president of the firm who audits many of the country’s broadband meters says that he can’t certify the measurements produced by five out of seven of his clients’ meters because they don’t count your bits correctly.
Globally the average mobile user consumed 201 MB a month in 2012. In North America, we binged on more than triple that amount. By 2017, Cisco says, those numbers will increase by a factor of 10.
Last year when Cisco released the 2012 mobile VNI forecast, I noted that they had been building castles in the air, and needed to put foundations under them. In particular I was concerned about substantial changes in the assumed share of offloaded traffic, which had changed dramatically between the 2011 and 2012 reports. Specifically, in 2011 Cisco had estimated that in 2010 21% of US smartphone and tablet traffic was offloaded from mobile-connected devices, i.e. apparently excluding WiFi-only tablets and that would increase to 30% by 2015. In 2012 they estimated that 49% of this traffic was offloaded in 2011 and that would decrease to 46% in 2016. Now in the latest report actually in the VNI tool stats, not the report itself, Cisco estimate that:
Instead of worrying about the impact of a mobile data explosion, operators should worry about making it happen in the first place.
Mobile operators have been told for the last two or three years that they should be fretting about how to reduce network costs when faced with explosive data growth. Everybody in the industry will have seen many examples of the so-called ‘scissor-graph’ showing a curve for traffic and costs going one way and a curve for revenue heading off at 90 degrees.
