Currently, peer-to-peer file sharing systems are playing a dominant role in the content distribution over Internet. ...
Therefore understanding the impact of peer-to-peer traffic on large scale networks is significant and instrumental for the design of new systems. ...

We find that network awareness in terms of both capacity and locality potentially degrades system QoS as a whole and that capacity awareness faces effort-based unfairness, but enables contribution-based ...
Thus, directly applying the idea of peer locality to existing P2P streaming systems is non-trivial. ...
