Abstract |
|
|
| We study the issue of P2P streaming system with transcoding and expose the fundamental characteristics and mathematical
theory of the system in the two-class network structure. We find out and prove that, in a two-class P2P streaming system, to provide
peers receiving data above some given flow rate, there is a lower bound of source server load. We give an algorithm to achieve this
minimal server load. We also compare the minimal server load by our algorithm with typical traditional design without transcoding
in various situations in our simulation experiments, and analyze how much benefit system can get from the utilization of transcoding
technique. The results show that, if transcoding technique is utilized appropriately, better performance of two-class P2P streaming
system can be achieved. |
