Fully distributed systems, typically termed Peer-to-peer (P2P) systems, seem to be of much more interest these days, especially moving from a pure file sharing use to a more commercial use and application. While the more traditional Client/Server (C/S) system belongs clearly to the distributed system, many new applications tend to prefer in certain cases a P2P-based approach. This lecture on "Peer-to-Peer Systems and Applications" outlines the major technology alternatives of P2P, introduces overlay networks, analyzes key P2P features, checks on implementation and deployability aspects, and investigates on scalability, efficiency, reliability, and commercial applicability. Search schemes, security mechanisms, and wireless use of P2P systems complete the overall P2P view. Based on a number of sample P2P systems the huge potential of them is outlined and applied in a challenge task in practical exercises.
This lecture's goals encompass the gaining of knowledge of principles and protocols in fully decentralized (P2P) communications. While client/server aspects are of importance, the less traditional, but emerging peer-to-peer scheme and its integration into today's Internet is addressed in theory and in a practical challenge task to be designed and implemented. Thus, respective P2P protocol details and system aspects for will be covered, showing potentials as well as problems.
The content of this course include introduction to basic concepts, structured and unstructured P2P systems, including distributed hash tables as important building blocks. Based on these building blocks, properties and mechanisms of distributed systems, its advantages and disadvantages are presented. Topics such as mobile P2P systems applications, Bitcoin, WebRTC, P2P streaming, distributed storage are discussed as well as their technical characteristics and economic aspects.The detailed topics and timing of the lecture is available at Lecture
