Influencia del Buffer del Router en la Distribucíon de Video P2P-TV
This addresses network performance issues for P2P-TV users, but it is incremental as it builds on existing simulation and trace analysis methods.
The study analyzed router buffer behavior in managing P2P-TV video traffic, finding that buffer performance was similar across access technologies, but high volumes of small packets could impair video quality and prevent content retransmission.
This work presents a study of the behaviour of the router buffer when managing the traffic of P2P-TV applications, where a number of peers exchange video content. First, a summary of the characteristics of SOPCast is presented. Then, the results obtained in simulation tests using different buffer policies are presented. Real traces of the application, obtained from a research project, have been used for the tests, sharing the Internet access with different amounts of background traffic. The results show that a similar buffer behaviour for all the access technologies. In addition, the big amount of small packets generated may impair the video traffic, thus avoiding the retransmission of the contents by the application.
