The Quest for Balancing Peer Load in Structured Peer-to-Peer Systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

Structured peer-to-peer (P2P) systems are considered as the next generation application backbone on the Internet. An important problem of these systems is load balancing in the presence of non-uniform data distributions. In this paper we propose a complete ...

Beyond "Web of Trust": Enabling P2P E-commerce

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

The huge success of eBay has proven the demand for customer-to-customer (C2C) electronic commerce. eBay is a centralized infrastructure with all its scalability problems (network bandwidth, server load, availability, etc.). In this paper we argue that C2C ...

Updates in Highly Unreliable, Replicated Peer-to-Peer Systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

In this paper we study the problem of updates in truly decentralised and self-organising systems such as pure P2P systems. We assume low online probabilities of the peers (

Handling Identity in Peer-to-Peer Systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

Due to the limited number of available IP addresses most computers on the Internet use dynamic IP addresses which causes problems for applications that have to maintain rout-ing tables, for example, peer-to-peer systems. To overcome this we propose unique ...

Lazy Parameter Passing

Patrick Eugster

Peer-to-peer (P2P) systems are strongly decentralized and asynchronous distributed settings involving a potentially large number of hosts. A common programing model for P2P infrastructures is that of a distributed hashtable (DHT), though which peers share ...

A Framework for Semantic Gossiping

Karl Aberer, Manfred Hauswirth, Philippe Cudré-Mauroux

Today the problem of semantic interoperability in information search on the Internet is solved mostly by means of centralization, both at a sys-tem and at a logical level. This approach has been successful to a certain extent. Peer-to-peer systems as a new ...
