With enormous growth of the number of Internet users and appearance of new applications,characterization of lntemet traffic has attracted more and more attention and has become one of the major challenging issues in telecommunication net-work over the past few years. In this paper,we study the network traffic pattern of the aggregate traffic and of specific application traffic,especially the popular applications such as P2P,VoIP that contribute most network traffic. Our study verified that majority Internet backbone traffic is contributed by a small portion of users and a power function can be used to approximate the contribution of each user to the overall traffic. We show that P2P applications are the dominant traffic contributor in cur-rent Internet Backbone of China. In addition,we selectively present the traffic pattern of different applications in detail.
