Influencia del Buffer del Router en la Distribuc\'ion de Video P2P-TV

TL;DR

This study investigates how router buffer management affects P2P-TV video streaming, revealing that buffer behavior is similar across technologies and small packets can hinder video retransmission, impacting overall quality.

Contribution

It provides an analysis of router buffer policies on P2P-TV traffic using real traces and simulation, highlighting the impact of small packets on video content retransmission.

Findings

Buffer behavior is similar across access technologies.

Small packets may impair video retransmission.

Buffer policies influence P2P-TV traffic performance.

Abstract

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.
