Cisco® Visual Networking Index (VNI), an ongoing initiative to track and forecast the impact of visual networking applications have released a new forecast document. Cisco Visual Networking Index: Forecast and Methodology, 2012–2017.
Some highlights from the paper relating to Video delivery:
• Globally, consumer Internet video traffic will be 69 percent of all consumer Internet traffic in 2017, up from 57 percent in 2012. This percentage does not include video exchanged through peer-to-peer (P2P) file sharing. The sum of all forms of video (TV, video on demand [VoD], Internet, and P2P) will be in the range of 80 to 90 percent of global consumer traffic by 2017.
• Video-on-demand traffic will nearly triple by 2017. The amount of VoD traffic in 2017 will be equivalent to 6 billion DVDs per month.
• Content Delivery Network (CDN) traffic will deliver almost two-thirds of all video traffic by 2017. By 2017, 65 percent of all Internet video traffic will cross content delivery networks in 2017, up from 53 percent in 2012.
