Multi-window FTP Systems in Java: A Network Client RAJKUMAR and BIJO THOMAS Operating Systems Group Centre for Development of Advanced Computing

Multithreaded programming is a conceptual paradigm for programming where programs are divided into two or more processes which can be run in parallel. With interactive, networked programs we find that there are many problems best solved concurrently. The work described here is a GUI based multi-threaded FTP package with which you can operate on any number of sites simultaneously. The package is designed as a powerful sophisticated visual tool for transferring files over the network. Multiple ftp sites can be opened simultaneouly and the directory tree of each location is displayed in separate windows. The basic operations can be done using mouse drag and drop techniques. Also the entire set of commands are available by means of a menu system. The multithreading features of Java enable multiple file transfers at a time thereby reducing the effects of network communication latency. This tools also support file transfers between nodes of a cluster exhibiting a single system image In this paper we discuss the FTP overview, FTP model and package architecture.
