摘要：File downloading process on Internet is generally slow. Here we will discuss about design and simulation of a distributed and synchronized file transfer protocol meant for the internet applications. The approach consists of centralized server which distributes the downloading process across multiple file servers and this is based on QoS parameter as available bandwidth. The client continuously monitors the FTP flows to detect slow servers and accordingly adjusts the file distribution. This parallelized FTP approach, stabs for the solution of the problem of slow downloads of bulky multimedia files while at the same time optimizing the utilization of mirror servers. This approach proposes simultaneous downloads of file from multiple file servers, and is combination of DAP and P-FTP. The performance can be increased by usage of slow server detection and link failure algorithms. In this paper, simulation is presented; which shows at least 50% reduction in download time, when compared to the traditional filetransfer approach.
