Optimistic Algorithms for Partial Database Replication

Nicolas Schiper, Rodrigo Malta Schmidt, Fernando Pedone

In this paper, we study the problem of partial database replication. Numerous previous works have investigated database replication, however, most of them focus on full replication. We are here interested in genuine partial replication protocols, which req ...

Considerations on the design of cut-and-cover tunnels

Aurelio Muttoni, Laurent Vulliet, Vincent Labiouse, Sylvain Plumey

The communication shows an alternative for introducing soil-structure interaction in the analysis of cut-and-cover tunnels. An uncoupled method is illustrated through two examples representative of the situations found in practice. The main features of eac ...

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 ...

Soft real-time analysis of asynchronous agreement algorithms using Petri nets

Nicoleta Sergent

A distributed algorithm comprises a collection of sequential-code entities, which are spread over different computers connected to a network. The process of designing a distributed algorithm is influenced by the assumptions we make on the computational env ...
