The structure of network traffic is changing. It is estimated that 31% of smartphone users now make no traditional voice calls in a given week, and 36% of 18-24 year olds are ‘data exclusive’, so the pressure on infrastructure providers is increasing rapidly. In its latest Visual Networking Index, Cisco forecast data traffic will reach 49 Exabytes within the next five years. An exabyte is equal to a quintillion, and 49 quintillion looks like this: 49,000,000,000,000,000,000. That’s a lot of data traffic.
