These days many people, when hearing the term Peer-to-Peer network (P2PN), think of unrestricted and potentially illegal ``file-sharing'' on the Internet. In traditional P2PN usually a limited number of peers make a set of files available. These files become inaccessible when those peers leave the network. Furthermore inevitable fluctuation of the peer population makes the attainment of a specific quality of service in terms of correct and complete file downloads hard or even impossible. In what follows the author also wants to foster the emerging conception that the concept of Peer-to-Peer networks has much more potential than simple file-sharing.
In the focus of this dissertation are the problems caused and aggravated by peer population fluctuation. Starting from an analysis of the problems in 2nd generation P2PN, the author expounds his own definition and approach to a Peer-to-Peer data store (P2PD) that, in contrast to a pure P2PN, stores data items, once inserted, reliably with high probability. The P2PD of the author offers the following unique selling points in comparison with related P2PN:
Instead of a single peer being responsible for availability, accessibility, and security of a set of data items, a group of peers is. The author calls such a group a ``replication group'' because all peers belonging to such a group store an identical copy of the group's set of data items. Peer joins and leaves thus affect the availability of data items much less than they would in 2nd generation P2PN
