Cisco says global IP traffic will double in 5 years

The headline forecast from US networking giant Cisco’s annual Visual Networking Index is that global IP traffic will increase from 72.4 exabytes per month in 2015 to 168 exabytes per month in 2019 – more than double.

This represents an increase on its previous forecast, which Cisco attributes to the following:

  • A greater proportion of the world’s population using the internet, which is forecast to top 50% by 2019
  • An explosion in internet connected devices, with the number expected to jump from 14 billion in 2014 to 24 billion in 2019
  • Faster connections – fixed and mobile – with average global fixed broadband speeds set to double by 2019
  • Proportion of IP traffic accounted for by video to increase from two thirds to four fifths thanks to advanced video services such as UHD
  • Proportion of IP traffic accounted for by mobile devices to increase from half to two thirds
  • M2M IP traffic to increase 15-fold by 2019
  • Online gaming and other streaming services such as music and video conferencing

“It took 32 years – from 1984 to 2016 – to generate the first zettabyte of IP traffic annually,” said Doug Webster, VP of Service Provider Products and Solutions Marketing at Cisco. “However, as this year’s Visual Networking Index forecasts, it will take only three additional years to reach the next zettabyte milestone when there will be more than 2 zettabytes of IP Traffic annually by 2019.”
