According to the 10th annual Cisco Visual Networking Index (VNI) Forecast, annual Internet Protocol (IP) traffic will triple between 2014 and 2019, when it will reach a record 2 zettabytes.
Factors expected to drive traffic growth include the growth of video services. Video will account for 80 percent of all IP traffic by 2019, up from 67 percent in 2014. The evolution of advanced video services (e.g., UHD and spherical/360 video) and increasingly video centric M2M applications are anticipated to create new bandwidth and scalability requirements for service providers.
Residential, business and mobile consumers continue to have strong demand for advanced video services across all network and device types, making quality, convenience, content/experience and price key success factors.
Cisco predicts that global IP traffic will reach 168 exabytes per month by 2019, up from 59.9 exabytes per month in 2014. In 2019, nearly as much traffic will traverse global IP networks than all prior “Internet years” combined (from 1984 to the end of 2013).
