Nowadays, networked computers are present in most aspects of everyday life. Moreover, essential parts of society come to depend on distributed systems formed of networked computers, thus making such systems secure and fault tolerant is a top priority. If t ...
Peter Urban, Xavier Defago and Andre Schiper: Chasing the FLP Impossibility Result in a LAN or How Robust Can a Fault Tolerant Server Be? Keywords: replication, atomic broadcast, consensus, measurements, robustness, high load, LAN, FLP impossibility Abstra ...
Performance Comparison of a Rotating Coordinator and a Leader Based Consensus Algorithm Peter Urban, Naohiro Hayashibara, Andre Schiper, and Takuya Katayama Protocols that solve agreement problems are essential building blocks for fault tolerant distribute ...
Comparing the Performance of Two Consensus Algorithms with Centralized and Decentralized Communication Schemes Peter Urban and Andre Schiper Protocols that solve agreement problems are essential building blocks for fault tolerant distributed systems. While ...
The fair exchange problem is key to trading electronic items in systems of mutually untrusted parties.We consider modern variants of such systems where each party is equipped with a tamper proof security module. The security modules trust each other but ca ...
Reliable distributed protocols, such as consensus and atomic broadcast, are known to scale poorly with large number of processes. Recent research has shown that algorithms providing probabilistic guarantees are a promising alternative for such environments ...

Peter Urban and Andre Schiper Comparing Distributed Consensus Algorithms Protocols that solve agreement problems are essential building blocks for fault tolerant distributed systems. While many protocols have been published, little has been done to analyze ...
A. Coccoli, P. Urban, A. Bondavalli, and A. Schiper. Performance analysis of a consensus algorithm combining Stochastic Activity Networks and measurements. In Proc. Int'l Conf. on Dependable Systems and Networks (DSN), pages 551-560, Washington, DC, USA, J ...
Fault tolerance can be achieved in distributed systems by replication. However, Fischer, Lynch and Paterson have proven an impossibility result about consensus in the asynchronous system model. Similar impossibility results have been established for atomic ...
