In the 2018 edition of its Visual Networking Index (VNI), Cisco announced that IP traffic is expected to triple in five years to 4.8 zettaocytes by 2022 (396 exabytes per month from 122 in 2017).
This growth is mainly due to two factors: the increase in the number of Internet users and the increase in the number of connected devices. According to Cisco, 4.8 billion people will use the Internet in 2022 compared to 3.4 billion in 2017. The number of fixed and mobile connections would increase to 28.5 billion within five years, half of which would concern Machine-to-Machine (M2M) and IoT.
According to the American network equipment manufacturer's forecasts, global Internet traffic generated by consumer uses will increase from 267 exabytes per month in 2017 to 333 exabytes in 2022. Business and government traffic is expected to double and represent 16% of total IP traffic.
The network preferred by users would be the fixed Internet with 273 exabytes per month at the end of 2022. Mobile IP traffic would follow with 77 exabytes but would be ahead of managed IP with 45 exabytes per month.
Internet video is also expected to grow strongly and represent 82% of global traffic in 2022, an increase of 7 points, all networks combined.
The adoption of SD-WAN in companies is also confirmed, with traffic increasing by 37% per year.
