Priority-based R2CP for multipoint-to-point video streaming
Jung-Shan Chien, Sheng-Ching Lin, Ray-I Chang, Chia-Hui Wang · 2008
In a P2P network, the same content can derive from multiple sources, which is to say that there can be multiple incomings. As RTP used popularly in video streaming cannot handle multipoint-to-point data streams, R2CP was proposed to resolve this drawback. However, R2CP does not discriminate the data packets which are critical to the quality of video streaming, so there is a great risk that the critical data packets may be dropped when network is congestion. This paperdaggerproposes P-R2CP (Priority-based R2CP) to effectively decrease the loss ratio of critical data packets in multipoint-to-point video streaming. Experimental results indicate that, as less critical data packets are dropped, the proposed method can maintain the good playback quality.
