Highlights of Cisco’s Internet Traffic Report & Forecast

According to statistics from Cisco Systems global average Internet traffic will increase 3.2-fold by 2021 and will reach 717 Tbps.  Busy hour Internet traffic will increase 4.6-fold by 2021 and will reach 4.3 Pbps. Globally, the number of DDoS attacks greater than 1 Gbps will grow 2.5-fold from 2016 to 2021, a compound annual growth rate of 20%.

In 2021:

  • Fixed access and Wi-Fi networks represented 52.6% of the world’s total Internet traffic in 2021.
  • Mobile networks – including 4G and 5G networks – handled just 20.5% of the world’s total Internet traffic in 2021.

According to Cisco’s findings, future trends favor mobile. The firm reported that fixed and Wi-Fi networks were approximately 52.1% of total Internet traffic in 2016 – virtually the same number as 2021.

Global mobile networks handled just 9.8% of total Internet traffic in 2016, but that figure more than doubled in 2021.

It’s interesting that Cisco predicts an average WiFi speed of 92 Mbps by 2023, while the average mobile speed will then be less than half of that at 44 Mbps.
