More IP traffic in next five years than in history of Internet

The new Visual Networking Index (VNI) by Cisco predicts more traffic will be created in 2022 than in the 32 years since the internet started. By 2022, more than 28 billion devices and connections will be online.

THE INTERNET IS MADE UP OF THOUSANDS of public and private networks around the world. And since it came to life in 1984, more than 4.7 zettabytes of IP traffic have flowed across it. That′s the same as all the movies ever made crossing global IP networks in less than a minute.

Yet the new Visual Networking Index (VNI) predicts that this is just the beginning. By 2022, more IP traffic will cross global networks than in all prior ′internet years′ combined up to the end of 2016. In other words, more traffic will be created in 2022 than in the 32 years since the internet started. Where will that traffic come from? All of us, our machines and the way we use the internet. By 2022, 60 percent of the global population will be internet users. More than 28 billion devices and connections will be online. And video will make up 82 percent of all IP traffic.

"The size and complexity of the internet continues to grow in ways that many could not have imagined. Since we first started the VNI Forecast in 2005, traffic has increased 56-fold, amassing a 36 percent CAGR with more people, devices and applications accessing IP networks," said Jonathan Davidson, senior vice president and general manager, Service Provider Business, Cisco.

"Global service providers are focused on transforming their networks to better manage and route traffic, while delivering premium experiences. Our ongoing research helps us gain and share valuable insights into technology and architectural transitions our customers must make to succeed."


From 2017 to 2022, Cisco predicts global IP traffic will more than triple. Global IP traffic is expected to reach 396 exabytes per month by 2022, up from 122 exabytes per month in 2017. That′s 4.8 zettabytes of traffic per year by 2022. By 2022, the busiest hour of internet traffic will be six times more active than the average.

Key predictions for 2022

Cisco′s VNI looks at the impact that users, devices and other trends will have on global IP networks over a five-year period. From 2017 to 2022, Cisco predicts:

  • Global IP traffic will more than triple
  • Global IP traffic is expected to reach 396 exabytes per month by 2022, up from 122 exabytes per month in 2017. That′s 4.8 zettabytes of traffic per year by 2022.

By 2022, the busiest hour of internet traffic will be six times more active than the average. Busy hour internet traffic will grow by nearly five times (37 percent CAGR) from 2017 to 2022, reaching 7.2 petabytes per second by 2022. In comparison, average internet traffic will grow by nearly four times (30 percent CAGR) over the same period to reach 1 petabyte by 2022.

Global internet users will also make up 60 percent of the world′s population. There will be 4.8 billion internet users by 2022. That′s up from 3.4 billion in 2017 or 45 percent of the world′s population.

Global networked devices and connections will also reach 28.5 billion. By 2022, there will be 28.5 billion fixed and mobile personal devices and connections, up from 18 billion in 2017-or 3.6 networked devices/connections per person, from 2.4 per person.

More than half of all devices and connections will be machine-to-machine by 2022, up from 34 percent in 2017. That′s 14.6 billion connections from smart speakers, fixtures, devices and everything else, up from 6.1 billion.

Global broadband, Wi-Fi and mobile speeds will double or more during the same period. Average global fixed broadband speeds will nearly double from 39.0 Mbps to 75.4 Mbps.

Average global Wi-Fi connection speeds will more than double from 24.4 Mbps to 54.0 Mbps. Average global mobile connection speeds will more than triple from 8.7 Mbps to 28.5 Mbps. Video, gaming and multimedia will make up more than 85 percent of all traffic.

IP video traffic will quadruple by 2022. As a result, it will make up an even larger percentage of total IP traffic than before-up to 82 percent from 75 percent.

Gaming traffic is expected to grow nine-fold from 2017 to 2022. It will represent four percent of overall IP traffic in 2022.

Virtual and augmented reality traffic will skyrocket as more consumers and businesses use the technologies. By 2022, virtual and augmented reality traffic will reach 4.02 exabytes/month, up from 0.33 exabytes/month in 2017.
