Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distributed transactional mechanisms, such as atomic commitment. We present the database state mac ...
This report describes the design of a Replication Framework that facilitates the implementation and com-parison of database replication techniques. Furthermore, it discusses the implementation of a Database Replication Prototype and compares the performanc ...
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 ...
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 ...
In network (e.g., Web) servers, it is often desirable to isolatethe performance of different classes of requests from each other. That is, one seeks to achieve that a certain minimalproportion of server resources are available for a class ofrequests, indep ...
Exploiting Atomic Broadcast in Replicated Databases F.Pedone, R.Guerraoui and A.Schiper Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distribute ...
Distributed computing is reshaping the way people think about and do daily life activities. On-line ticket reservation, electronic commerce, and telebanking are examples of services that would be hardly imaginable without distributed computing. Nevertheles ...

Multimedia interfaces increase the need for large image databases, capable of storing and reading streams of data with strict synchronicity and isochronicity requirements. In order to fulfil these requirements, we use a parallel image server architecture w ...
