摘要：The Peer-to-peer (P2P) computing has been one of the emerging technologies in distributed file sharing. Experimental studies show that for a file download, service capacity fluctuation takes minutes to several hours. For a P2P one of the fundamental performances metric is the average download time. The common approach to analyse the average download time is average service capacity. Heterogeneity and fluctuation have significant impact on service capacity and hence the averages download time. Random Chunk Based Switching is one of the file downloading scheme where, the file to be downloaded is divided into many chunks but the short comes of this scheme are user sequentially download one chunk at a time, also if user gets stuck in a low service capacity peer, downloading a fixed amount of bytes from that peer may take a long time and here chunk size remains fixed and it does not change with time. We propose a new approach where chunk size changes with time and our model provides no. Of parallel connections which changes with hardware utilization which overcomes the shortcomings of Random Chunk Based Switching.
