Abstract:  This paper proposes a P2P file distribution model based on deterministic network coding (DLNCCD).This coding method can be applied to the specific multicast uniform network topology to reduce complexity of network coding, improve decoding efficiency, and ensure maximum network coding gain. The
experimental results show that the total distribution time can reduce by 10%15%, and the throughput can improve by 17%21%, and the average download time can reduce by about 20%, Therefore the performance of the file distribution system is improved.

Key words: P2P, deterministic network coding, file distribution, Uniform Network
