Push Popular Segments in P2P VoD System: Possibility and Design
—Video-on-Demand (VoD) services have attracted a lot of attentions in recent years. Measurement studies show that VCR (Video Cassette Recorder) operations, such as pause, rewind, and fast forward/backward, influence the pattern of access to video segments and viewers(session)’ sojourn time. Moreover, some VCR features (e.g., bookmarking [1]) newly proposed can further magnify such effects. This work analyzes the feasibility to discern popular segments (highlights) from normal non-popular segments (normal-content) and how to reduce playback jitter in P2P streaming by leveraging the difference in segment popularity. Our contributions are two folds. First, a user playback model is presented, based on which we come to affirmative conclusion on the feasibility aforementioned. Besides, we also examine a real workload trace to validate the model and conclusions. Second, we propose a hybrid system, namely PITAPAT, which pro-actively Pushes out hIghlighTs And Pulls in normAl-contenT on de...
