Abstract (in Japanese) (See Japanese page) 
(in English) This work attempts to characterize workload of large-scale video sharing services such as YouTube and Smiley videos (Nico Nico Douga). The key technical contributions of this paper are twofold. We first propose a simple and effective methodology that identifies traffic flows originated from video hosting servers. The key idea behind our approach is to leverage the addressing/naming convention used in the large-scale server farms. Next, using the identified video flows, we study the workload of
video sharing services from an Internet edge site view. We reveal the intrinsic characteristics of the flow size distributions of video sharing services, which have not been known before. We show that the origin of the intrinsic characteristics is rooted on the differentiated service provided for free- and premium membership of the video-sharing services.
We also discuss the implications of the intrinsic characteristics of video-sharing services.
