This paper proposed a novel p2p streaming system and it incorporated the dynamic adaptation, peer lookup and packet loss.
The system considers the scenario that several peers provides video segment to one receiver which is different with other system and this method tries to increase the best video quality that the receiver can receive.
In this paper, the status of the peers are monitored and the roles (active or non-active) are changed dynamically.
Three selections algs are proposed and compared: random, end-to-end, topology-aware selection.
Each peer is associated with two parameters: declared rate and available rate.
Shortcoming:
How to coordinate the sending of packers from several peers to one receiver is not described in detail. In simulation, three selections strategies are not compared. One quality of video is transmitted and only bandwidth resources is considered.
