In the fifth annual Cisco(R) Visual Networking Index (VNI) Forecast (2010-2015) released yesterday, Cisco is predicting that that the number of network-connected devices will be more than 15 billion, twice the world's population, by 2015 and expect the proliferation of tablets, mobile phones, connected appliances and other smart machines will drive this growth. The company also said the total amount of global Internet traffic will quadruple by 2015 and reach 966 exabytes per year.They expect by 2015, more than one million minutes of video per second will run throught the pipelines, or equal to two years of viewing every second.
The projected increase of Internet traffic between 2014 and 2015 alone is 200 exabytes, which is greater than the total amount of Internet Protocol traffic generated globally in 2010. On the verge of reaching 1 zettabyte, which is equal to a sextillion bytes, or a trillion gigabytes by 2015, global IP traffic growth is driven by four primary factors, according to Cisco. They are:
1. An increasing number of devices – by 2015, there will be nearly 15 billion network connections via devices -- including machine-to-machine -- and more than two connections for each person on earth.
2. More Internet users: By 2015, there will be nearly 3 billion Internet users -- more than 40 percent of the world's projected population.
3. Faster broadband speed: The average fixed broadband speed is expected to increase four-fold, from 7 megabits per second in 2010 to 28 Mbps in 2015. The average broadband speed has already doubled within the past year from 3.5 Mbps to 7 Mbps.
4. More video: By 2015, 1 million video minutes -- the equivalent of 674 days -- will traverse the Internet every second.
