Replicated Invocation

André Schiper, Stefan Pleisch, Arnas Kupsys

In today's systems, application are composed from various components that may be located on different machines. The components may have to collaborate in order to service a client request. More specifically, a client request to one component may trigger a ...

Group communications and database replication

Matthias Wiesmann

Databases are an important part of today's IT infrastructure: both companies and state institutions rely on database systems to store most of their important data. As we are more and more dependent on database systems, securing this key facility is now a p ...

Fast Indulgent Consensus with Zero Degradation

Rachid Guerraoui, Partha Dutta

This paper describes a new consensus algorithm for the asynchronous message passing system model augmented with an unreliable failure detector abstraction: channels are reliable, processes can fail by crashing, and the detection of crashes are not reliable ...

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 ...

Deconstructing Paxos

Rachid Guerraoui, Partha Dutta, Romain Boichat

The Paxos part-time parliament protocol of Lamport provides a non trivial but very practical way to implement fault-tolerant deterministic services over a distributed message passing system. This paper deconstructs Paxos and modularly reconstructs more res ...

Replication et Durabilité dans les systèmes répartis

Distributed dats bases and data replication are recognised today as an efficient way to increase availability and fiability in data bases. The problem of mutual co-herence of copies is however introduced. Updating data is to be done on all copies. The noti ...

Primary-backup replication: From a time-free protocol to a time-based implementation

André Schiper

Fault-tolerant control systems can be built by replicating critical components. However, replication raises the issue of inconsistency. Multiple protocols for ensuring consistency have been described in the literature. PADRE (Protocol for Asymmetric Duplex ...

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 ...
