Today Cisco Systems released its annual Visual Networking Index (VNI), and the results are intriguing if not exactly surprising. By the end of this year, Cisco predicts that video will exceed P2P as the top traffic contributor, making it the first year that P2P has not been the leading traffic type. The company also says that by 2014 all forms of video—TV, VoD, Internet video, and P2P—will comprise more than 91% of all internet traffic. That doesn’t mean that 91% of all internet traffic will involve video, of course, and the company notes that popular activities like VoIP are relatively light in bandwidth consumption. It’s also worth noting that the report doesn’t distinguish between uploading and downloading of video; we can only assume the 91% includes uploading, downloading, streaming, progressive download, and file sharing.
And of that video traffic in 2014, Cisco expects 42% of it to be made up of 3D and HD content, though notably the report doesn’t offer a definition of HD video, so we don’t know if it’s 1080p, 720p, or both (or a more nebulous definition.
See the graph below for a breakdown of 12 categories of internet traffic.
