1Cisco Explains How Global Network Traffic Will Reach 2ZB Milestone
by Jeffrey Burt
2In Network Traffic, the Trend Is Upward
Between 2014 and 2019, the amount of traffic running annually on networks worldwide will triple, to 2 zettabytes. (Two zettabytes is 12 times more than all the Internet traffic generated in 2009, and equal to 30 hours of ultra-HD video per person in the world.)
3It’s People–and Many Are on the Internet
More people are getting access to networks and the Internet. In 2014, there were 2.8 billion Internet users, about 39 percent of the world’s population. By 2019, there will be about 3.9 billion, or 51 percent of the population.
4There Also Will Be More Devices and Connections
There will be 24 billion networked devices and connections online by 2019, about 10 billion more than last year. The devices range from smartphones and tablets, to ultra-HD TVs, to wearable technology and machine-to-machine (M2M) connections.
5More People Will Have More Devices
Last year, each person on average had two networked devices or connections. By 2019, that average will jump to 3.2 per capita. Carriers will need a strong IPv6 strategy to handle the volume and complexity that comes with all these devices, Cisco researchers say.
6Fixed Broadband Speeds Are Increasing
The average speed of fixed broadband connections will more than double between 2014 and 2019, growing from 20.3M bps to 42.5M bps. By that year, 33 percent of all global fixed broadband connections will be faster than 25M bps.
7Eyes Are on Video
Last year, video accounted for 67 percent of all IP traffic. That will jump to 80 percent. That’s no surprise, given that Netflix streaming videos at times can account for about a third of all Internet traffic.
8It’s Not Just Quantity, but Quality
It’s not only the amount of video that is impacting network traffic, but also the quality, from standard video to HD video to ultra-HD video, and the higher the quality, the more bandwidth will be needed. In 2014, ultra-HD video accounted for 0.6 percent of video traffic. That will jump to 13.9 percent in 2019.
9Video Coming in Smaller Packages
By 2019, smartphones will account for more than 40 percent of the world’s video-capable devices.
10Better to See You With
On the business side of things, desktop and personal video conferencing will be the fastest-growing Internet service, increasing 23.5 percent annually between 2014 and 2019. The number of users will jump from 76 million last year to 220 million by 2019.
11Mobility on the Move
Last year, 54 percent of IP traffic came from fixed connections. By 2019, WiFi and mobile-connected devices will generate 67 percent of the traffic, with WiFi—at 53 percent—owning the lion’s share.
12M2M and the Internet of Everything
The Internet of everything (IoE)—which Cisco officials say includes the Internet of things—is growing, which means M2M connections are growing worldwide. Such connections will triple between 2014 and 2019—to 10.5 billion in 2019.
13IoE in Business and the Home
A broad range of business verticals—such as agriculture, health care, retail and transportation—and homes (through video security, smart meters and lighting controls) are adopting IoE, and annual M2M traffic across the globe will jump 15-fold through 2019, hitting 4.6 exabytes, or 2.7 percent of all IP traffic.
14The Game Is Afoot
Cisco researchers are predicting that traffic related to downloads of games will jump, due in large part to the increased storage capacity of newer gaming consoles, growth in upstream cloud traffic and more fiber connections.
15Asia-Pac and North America Lead the Way
By 2019, the Asia-Pacific region will generate 54.4 exabytes of traffic a month (a 2.6-fold increase over 2014), while North America will generate 49.7 exabytes (a 2.5-fold increase). The Middle East and Africa will be the smallest in terms of exabytes generated each month—9.4—but will also be the fastest growing, with a 6.3-fold increase.
16U.S. Will Be Top Traffic Producer
By 2019, the United States will generate 45.7 exabytes of traffic each month, followed by China, with 21.9 exabytes. South Africa and Saudi Arabia will have the fastest rate of growth, each with 44 percent.
