1 Peer-assisted Video Streaming with RTMFP Flash Player: A Measurement Study on PPTV Shan Zou, Student Member, IEEE, Qiang Wang, Junqiang Ge, and Ye Tian, Member, IEEE Abstract—RTMFP is a protocol developed by Adobe for TABLE I multimedia delivery under both client-server and peer-to-peer ARCHITECTURES AND STREAMING PROTOCOLS OF POPULAR VIDEO paradigms. Currently, major Internet video service providers SERVICE PROVIDERS IN CHINA such as PPTV and iQIYI have already built their web-based video streaming systems with RTMFP. In such a system, user Service provider Architecture Streaming protocol Youku CDN HTTP only needs to install a Flash Player plug-in on his web browser, CNTV P2P UDP based proprietary protocol and can stream videos in a peer-assisted way. Tudou CDN HTTP Despite its wide usage, RTMFP has received little attention PPTV CDN + P2P HTTP + RTMFP from the measurement community. In this paper, we select iQIYI CDN + P2P HTTP + RTMFP PPTV as an example, and study the RTMFP video stream- Sohu TV CDN + P2P HTTP + RTMFP ing technology with a measurement approach. We reveal the architecture of PPTV’s RTMFP streaming system, and show that comparing with proprietary P2P networks, the RTMFP network has a different content distribution policy, and exhibits CNTV and Xunlei Kankan [6]. A problem of this approach different features on peers’ streaming behaviors, potential system is that users may not be willing to install many different bottleneck, and network dynamics. We also study RTMFP’s video proprietary plug-ins from different providers.
