According to Cisco Visual Networking Index (VNI), the global IP traffic will triple the growth at a CAGR of 22% over the next five years. The new internet users will grow from the current three billion in 2015 to 4.1 billion by 2020, Cisco said.
The driver for this growth is mainly the global digital transformation that grows due to the adoption of personal devices and deployment of machine-to-machine (M2M) connections. Over the next five years, the global IP networks are said to support up to 10 billion new devices and connections, increasing from 16.3 billion in 2015 to 26.3 billion by 2020.
The IP traffic is also driven by the advancements in the Internet of Things (IoT). The IoT applications are creating new network requirements and hence, the traffic increases. The global M2M connections are estimated to grow to 12.2 billion by 2020 from the 4.9 billion registered in 2015, representing 46 percent of total connected devices.
The connected health consumer segment will report the strongest growth, from 144 million in 2015 to 729 million in 2020. The connected home segment is another growth predicted by Cisco, which is expected to grow to 5.8 billion by 2020.
“The digital transformation is happening now for billions of consumers and businesses users across the globe,” said Doug Webster, vice president of service provider marketing, Cisco. “Innovation is imperative for Cisco and its service provider customers to deliver scalable, secure, high-quality services and experiences over all types of broadband network infrastructures.”
The video services will account for 79% of global Internet traffic by 2020, up from 63% in 2015. The world will reach three trillion Internet video minutes per month by 2020, which is five million years of video per month, or about one million video minutes every second. HD and Ultra HD Internet video will make up 82% of Internet video traffic by 2020, a rise up from 53% in 2015.
With the growing dependence on mobile and fixed broadband networks, security concerns are increasingly becoming top of mind for service providers, governments, businesses, and consumers. Among the security issues, DDoS attacks are projected to increase from 6.6 million to 17 million attacks.
