153 P2P Content Distribution Model Based on Network Coding Available to Purchase

Network coding brings significant performance to the network and new ideas to the P2P content distribution. The combination of network coding and P2P technology can solve some problems in P2P content distribution. In this thesis, we introduce a P2P content distribution model called scheduling-coding model which is based on segmented network coding after in-depth study of BT content distribution. It can solve the problems caused by network coding for large-scale content distribution. Its core ideas are network coding within segment and mixed segmentscheduling strategy among segments. Test results show that network coding brings remarkable performance to P2P content distribution system, but it introduces excessive computational complexity for large-scale content distribution which affects the performance of the system.
