Netflix is a massive bandwidth hog, or at least a new report from Sandvine would lead you to believe that. The data that they collected shows that Netflix use contributed 33 percent of downstream traffic in North America during peak hours. From 9 p.m. to 12 a.m., Netflix dominated the competition in data usage.
Amazon, by comparison, only accounted for 1.8 percent, and Hulu only managed to use 1.4 percent. During this time period, roughly 65 percent of non-cellular data was composed of audio- or video-streaming services. This means that Netflix accounts for over half of all streaming during the peak hours of usage.
Sandvine is predicting that Netflix will, by 2015, generate "two times the bandwidth of YouTube and 10 times that of competing services." Sandvine's numbers are created by collecting data from over 200 customers worldwide over a period of one month. Sandvine is in the business of selling Internet traffic-management systems.
