Characterizing Traffic Flows Originating from Large-Scale Video Sharing Services

چکیده
This work attempts to characterize network traffic flows originating from large-scale video sharing services such as YouTube. The key technical contributions of this paper are twofold. We first present a simple and effective methodology that identifies traffic flows originating from video hosting servers. The key idea behind our approach is to leverage the addressing/naming conventions used in large-scale server farms. Next, using the identified video flows, we investigate the characteristics of network traffic flows of video sharing services from a network service provider view. Our study reveals the intrinsic characteristics of the flow size distributions of video sharing services. 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 investigate temporal characteristics of video traffic flows.

A Fair Traffic Conditioner for the Assured Service in a Differentiated Services Internet
A research issue under investigation in the context of differentiated services (DiffServ) is the fair distribution of bandwidth between aggregates sharing the same Assured Forwarding (AF) class. Multiplexing both responsive and unresponsive flows, e.g. TCP and UDP respectively, leads to unfair sharing of the available bandwidth in over-provisioned networks. To date, much effort has concentrated...
متن کاملSender-driven bandwidth differentiation for transmitting multimedia flows over TCP
Over the years the Internet has shown extraordinary scalability and robustness in spite of the explosive growth in geographical reach, user population size, as well as network traffic volume. This scalability and robustness is, in no small part, supported by the Internet’s transport protocols, the Transmission Control Protocol (TCP) in particular. Nevertheless, with the rapid growth of multimed...
متن کاملMethod of Video-Measurements of Traffic Flow Characteristics at a Road Junction
In the theory of traffic flows the main characteristics are: intensity, speed, and density. They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly corre...
متن کاملA Peep on the Interplays between Online Video Websites and Online Social Networks
Many online video websites provide the shortcut links to facilitate the video sharing to other websites especially to the online social networks (OSNs). Such video sharing behavior greatly changes the interplays between the two types of websites. For example, users in OSNs may watch and re-share videos shared by their friends from online video websites, and this can also boost the popularity of...
