“…Since introducing intentional pauses is equivalent to increasing the playback time (cf. (Zhao et al, 2013)), our mode! could describe the effect of such pauses by reducing the playback rate Pw• We refer to this scenario as with Interaction Functionalities (IF).…”

Video on Demand services generate the Jargest amount of traffic in networks nowadays. Previous works have proposed integrating Content Delivery Networks (CON) and Peer-to-Peer (P2P) networks to satisfy this demand. However, their analytical methods do not consider al) the factors that affect the performance of these systems. Hence, we present a nove) comprehensive framework, based on a fluid mode), to evaluate VoD services over hybrid CDN-P2P systems. The proposed framework considers features of the service (e.g., size, coding-rate and popularity of the video), network attributes (e.g., upload data-rate capacity of servers and peers) and char acteristics of the behavior of the users (e.g., sojourn time, cooperativeness and frequency of random-seeks). Our framework allows a system to be evaluated under a wide variety of scenarios in terms of network-cost and Quality-of-Service (QoS) parameters and is flexible enough to mode) different resource allocation schemes, including a nove! scheme to distribute the upload network capacity. Despite the wide variety of considered factors, our framework is tractable and as accurate as discrete-models based on Markov chains.

“…3.2, we developed an analytical model to both qualitatively and quantitatively study the effect of VCR operations, such as forward seeks and pauses, on the server load [19]. To the best of our knowledge, our model is the first one that relates P2P VoD system performance to user behaviors such as the seek and pause pattern.…”

With the proliferation of interactive media, non-linear and noncontinuous media accesses have become a norm. Examples of such interactive media include video-on-demand, massive multiplayer virtual environments, massively multiplayer online game, zoomable video, Google Earth, and free-viewpoint video. To enable scalable delivery of these media contents to potentially millions of users, P2P architecture is often adopted. Non-linear and non-continuous user access pattern, however, pose new challenges on P2P interactive media streaming systems. These challenges include the need of more sophisticated prefetching scheme, increasing server load, high demand for short content discovery time, and difficulty of bandwidth allocation. We first try to understand the effect of non-linear and non-continuous media access on the streaming system performance, in particular, the server load, through analytical modeling. Then a novel user access pattern driven content discovery mechanism is proposed to address the content discovery challenge during non-continuous access. Works aiming at the rest of challenges are ongoing.
