A Hybrid Approach to Assess the Network Awareness of P2P-TV Applications
In this paper, the authors develop a general methodology to assess the level of network awareness and friendliness of P2P-TV applications. The methodology is based on a combination of active and passive measurement techniques and can be applied to any P2PTV system since it is designed to work considering such systems as a black-boxes. As an interesting case study, they then apply this methodology to PPLive, one of the most popular P2P-TV systems nowadays. Focusing on the video content distribution, they consider several per-path and per-peer metrics, investigating which of them mostly biases PPLive download preferences.
