From PC World: With internet traffic set to triple over the next five years or so, according to recent estimates from Nokia and Cisco Systems, Nokia thinks the time is right for a new range of high-end routers that can boost core capacity by a factor of six -- and even help 10-year-old devices to double their capacity.
Nokia predicts that by 2022, total internet traffic will reach 330 exabytes per month. (That's 330 million terabytes). For its part, Cisco forecasts it will grow at 24 percent per year from a base of 96 exabytes per month in 2016 to 278 exabytes per month in 2021.
That traffic growth will be driven by three things, according to Nokia: cloud services, 5G mobile networks, and the internet of things.
In a recent report on securing IoT, Cisco predicted there will be 50 billion connected devices by 2020; Nokia reckons there will be 100 billion IoT devices by 2025, up from 12 billion in 2017.
Protecting those billions of IoT devices against misuse will be vital if they are not to be turned against us. That's already a problem, with millions of connected cameras and home routers being subverted in recent months and used to launch DDoS (distributed denial of service) attacks. Cisco expects the number of DDoS attacks to grow from around 1.25 million in 2016 to 3.1 million in 2021. Nokia is more alarmist: It expects 10 million such attacks in 2017 alone -- although this may reflect different definitions of the level of traffic required to effectively deny service.
