Abstract [en]

Due to the fact that more and more people have access to the internet the need for file sharing will increase. With long distances, large files and long download times, a demand arises for better ways to download files. The idea to download the same file in several parts from multiple sources can decrease the load on the net, especially the load on some computers. The purpose of this project is to show how to implement file sharing software that supports downloading the same file from multiple sources. The system will be based on an already existing peer-to-peer file exchange system developed by Neo-Modus called Direct Connect or DC. The software implementation was made with Borland Delphi 6. This makes it possible to easily take the solution to the Linux platform with Borland Kylix. The report will introduce the main idea of DC and give an overview of how the system works. The DC-protocol will be discussed in detail and my solution will be presented with flow diagrams and a description of the structure of the application together with my ideas. Desirable features are: • Several simultaneous connections to DC-hubs • Several simultaneous download connections to DC-clients • Resuming downloading • Segmented downloading • Possibility for cross-platform development
