Internet Traffic to Quadruple by 2015, Says 思科
If network operators think they have congestion now, just wait four years. 今天, 思科 predicted that global Internet traffic will quadruple by 2015, reaching 966 exabytes per year.
Between 2014 and 2015 alone, 思科 expects traffic to jump by 200 exabytes. That's more than the total global traffic for 2010, the company notes.
Traffic of 966 exabytes is just shy of one zettabyte, which is sextillion bytes or a trillion gigabytes.
Video, naturally, is one of the causes for the rapid rise of traffic. 思科 says that by 2015, one million video minutes-which would run 674 days-will traverse the Net every second.
Other contributing factors include the increased number of connected devices, the growing number of Internet users, and faster broadband speed. 思科 says that the average fixed broadband speed should rise to 28 Mbps in 2015, up from 7 Mbps in 2010.
"The explosive growth in Internet data traffic, 尤其是视频, creates an opportunity in the years ahead for optimizing and monetizing visual, 虚拟, and mobile Internet experiences. As architect of the next-generation Internet, 思科 stands ready to help our customers not only accommodate this rapid expansion of Internet activity through the evolution of their networks but also help them thrive as a result of it," says Suraj Shetty, vice president of worldwide service provider marketing at 思科.
