Larry Greenemeier in Scientific American:
The number of smartphones, tablets and other network-connected gadgets will outnumber humans by the end of the year. Perhaps more significantly, the faster and more powerful mobile devices hitting the market annually are producing and consuming content at unprecedented levels. Global mobile data grew 70 percent in 2012, according to a recent report from Cisco, which makes a lot of the gear that runs theInternet. Yet the capacity of the world’s networking infrastructure is finite, leaving many to wonder when we will hit the upper limit, and what to do when that happens.
There are ways to boost capacity of course, such as adding cables, packing those cables with more data-carrying optical fibers and off-loading traffic onto smaller satellite networks, but these steps simply delay the inevitable. The solution is to make the infrastructure smarter. Two main components would be needed: computers and other devices that can filter their content before tossing it onto the network, along with a network that better understands what to do with this content, rather than numbly perceiving it as an endless, undifferentiated stream of bits and bytes.
