Using peer-to-peer (P2P) for file sharing services has shown better performance compared to client-server. However, it may not be effective for real-time streaming services, since the number of peers with the latest packet may be limited by the capacity of the streaming server. In using P2P for real-time streaming, the service provider manually allocates content server (CS) to various parts of P2P  network based on prediction. Allocating appropriate number of CS to appropriate location is important for providing stable service. Due to the unpredictability of the P2P. Manual allocation of CS may not be effective. This paper proposes method to dynamically discover the need of CS and allocate CS a proper position enhancing distribution for real-time streaming service.
