Cisco has emitted its latest Visual Networking Index, a global study of how much data passes through the world's wires.

Your correspondent feels it is best to take these big global studies with a pinch of salt: it's hardly in Cisco's interests to tell us all that global network traffic is slowing and there's no need to contemplate router upgrades for the next decade decade. But the company points out that it has consistently, over the six-year life of the Index, under-predicted traffic growth. The Index also has a reasonably robust methodology, relying on input from numerous analysts and network operators. Many vendor-commissioned studies use cold calling.
