Traffic Characteristics of Modern Video Streaming Service

The network traffic caused by mobile devices has been growing. Moreover, N-screen service which enables to watch video contents in various network devices accelerates the traffic growth. To handle the high network traffic effectively, the service provider should grasp the characteristics of the traffic. In this paper, we make a minute observation about the traffic of N-screen service using network traces of iShoot program which provide such a service. From the in-depth study, we find that there is a specific traffic pattern repeated every day. Also we observe contents popularity distribution and the traffic imbalance between the servers, and so on. These results can be used to design N-screen service architecture or maintain quality of video streaming service in the other mobile services.
