Solving Agreement Problems with Weak Ordering Oracles

André Schiper, David Cavin, Fernando Pedone

Agreement problems, such as consensus, atomic broadcast, and group membership, are central to the implementation of fault-tolerant distributed systems. Despite the diversity of algorithms that have been proposed for solving agreement problems in the past y ...

Probabilistic Atomic Broadcast

Fernando Pedone, Pascal Felber

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 ...

Ruminations on Domain-Based Reliable Broadcast

Fernando Pedone

A distributed system is no longer confined to a single administrative domain. Peer-to-peer applications and business-to-business e-commerce systems, for example, typically span multiple local-area and wide-area networks, raising issues of trust, security, ...

Probabilistic Queries in Large-Scale Networks

Fernando Pedone

Resource location is a fundamental problem for large-scale distributed applications. This paper discusses the problem from a probabilistic perspective. Contrary to deterministic approaches, which strive to produce a precise outcome, probabilistic approache ...

Using Optimistic Atomic Broadcast in Transaction Processing Systems

André Schiper, Matthias Wiesmann, Fernando Pedone

Atomic broadcast primitives are often proposed as a mechanism to allow fault-tolerant cooperation between sites in a distributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, s ...

Database Replication Techniques: a three parameter classification

André Schiper, Matthias Wiesmann, Fernando Pedone

Data replication is an increasingly important topic as databases are more and more deployed over clusters of workstations. One of the challenges in database replication is to introduce replication without severely affecting performance. Because of this dif ...

Understanding replication in databases and distributed systems

André Schiper, Matthias Wiesmann, Fernando Pedone

Replication is an area of interest to both distributed systems and databases. The solutions developed from these two perspectives are conceptually similar but differ in many aspects: model, assumptions, mechanisms, guarantees provided, and implementation. ...

Processing Transactions over Optimistic Atomic Broadcast Protocols

André Schiper, Fernando Pedone

Atomic broadcast primitives allow fault-tolerant cooperation between sites in adistributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, scalable applications on top of atomic ...

A Systematic Classification of Replicated Database Protocols based on Atomic Broadcast

André Schiper, Matthias Wiesmann, Fernando Pedone

Database replication protocols based on group communication primitives have recently emerged as a promising technology to improve database fault-tolerance and performance. Roughly speaking, this approach consists in exploiting the order and atomicity prope ...
