一种基于P2P的并行传输模型

Parallel Transmission Model Based on P2P

文件共享是P2P的重要应用之一,如何提高基于P2P的快速文件传输是保证用户满意度的重要技术。基于以往的研究,提出了一种数据分块与公平存储策略,基于存储策略给出了一个并行传输算法。其中存储策略较完全副本部署具有极大的空间优势,而并行传输算法不但可以适应网络的动态变化,而且对最后一个数据的传输时间也做了优化。实验结果表明:与理论分析一致,它较先前提出的模型具有更强的适应性和实际应用价值。

File sharing is one of the important application based on P2P,and how to improve the fast transmission based on P2P is important technology which is the guarantee of users＇ satisfaction.Based on the previous studies,this paper put forward a data fragment and fair storage strategy,then gave a parallel transmission algorithm.This stored strategy has more great space advantage than the entity copy.And this algorithm not only can adapt to the dynamic changes of the network,but also increase data transmission rate.The experiment result in dicates that it is in accordance with the theory and has a strong suitability and practical application value than previous model.
