Performance analysis and optimized operation of structured overlay networks

Overlay networks based on Peer-to-Peer (P2P) technology will be an important architectural component of the future Internet. The main objective of such networks is to efficiently look-up and share distributed resources. Structured P2P networks maintain a deterministic overlay structure that allows for queries to be resolved with a limited number of overlay hops. 
In this thesis, we develop and analyze concepts for highly scalable P2P systems. The design goal of these systems is maintenance of a correct structure, even in highly dynamic environments where participants frequently join and leave the network. We introduce novel concepts that result in a more stable overlay structure and significantly faster look-up times without increasing the required signaling overhead. Concluding, we introduce a general concept for realizing services and features in P2P-based Voice-over-IP applications.
