Historically, estimates of the annual report on the evolution of the Cisco data traffic on the Internet, are usually considered relatively conservative. Makes even more impressive, therefore, read the last report Visual Networking Index (VNI) Forecast 2011 to 2016 in four years that the volume of data generated on an annual basis on the Net will Zettabyte of 1.3 (a zettabyte equals one trillion of gigabytes).
In other words, with an evocative metaphor, it will be like every three minutes on the Internet transitassero all movies ever produced by man. Only in 2016, the amount of data exceeds that of all previous years put together since there ilk Web-boggling figures, due to the combined effect of several factors. One of these is the rise of online video, which grow from 792 million in 2011 and a half billion in 2016.
A second factor is the greater number of devices connected to the Internet not only PCs but also tablets, smart phones and home appliances. Cisco expects that in four years will be at least 18.9 billion network connections, on average two and a half person. Of these, 81%, compared with 94% of 2011 will take place by computer. Among the objects connected to the network will also adjust their entry into the television, that will have 6% of Internet access, even in 3D mode and in high definition.
The third major growth factor considered in the report is that of traffic mobility, which should increase by 18 times between 2011 and 2016. Fourth factor, the Wi-Fi from which Cisco believes will come more than half of the accesses. A statement gave no specific details but that should be carefully considered, especially in light of some studies to see in this type of connection a potential health hazard (though there is no definitive evidence in this sense, indeed other research seems to contradict the above conclusions shown). Globally, the area where you will record the highest growth of traffic will be the Asia-Pacific, followed by North America. The single nation with the largest absolute increase will be but India, with an average annual growth rate of 62%.
The U.S. company this year has added to the usual ratio VNI another document, called VNI Forecast Adoption Service that contains some estimates on the adoption of particular services in specific geographic areas. Interestingly, Western Europe, consumption of online video will replace, according to Cisco, the most widely used social networking as a service by residential users. Listening to online music will change to the service with the highest percentage growth over the period (+ 6.4%), absolute termni passing from 145 million current users, 197 million in 2016.
