Performance Comparison of Middleware Architectures for Generating Dynamic Web Content

Willy Zwaenepoel, Sameh Mohamed Elnikety, Emmanuel Cecchet

On-line services are making increasing use of dynamically generated Web content. Serving dynamic content is more complex than serving static content. Besides a Web server, it typically involves a server-side application and a database to generate and store ...

Tracing attacks and restoring integrity with LASCAR

Philippe Oechslin, Alexandre Aellig

We present a novel method to trace the propagation of intrusions or malicious code in networked systems. Our solution is aimed at large numbers of loosely managed workstations typical of a research environment as found in CERN. The system tags events which ...

MPEG-7 Description of Generic Video Objects for Scene Reconstruction

Touradj Ebrahimi

We present an MPEG7 compliant description of generic video sequences aiming at their scalable transmission and reconstruction. The proposed method allows efficient and flexible video coding while keeping the advantages of textual descriptions in database ...

Managing Trust in a Peer-2-Peer Information System

Karl Aberer, Zoran Despotovic

Managing trust is a problem of particular importance in peer-to-peer environments as one encounters frequently unknown agents. Existing methods for trust management based on reputation do however not scale as they rely on some form of central database or g ...

Exactly-Once Transactions

Rachid Guerraoui

A three-tier application is organized as three layers: human users interact with front-end clients (e.g browsers); middle-tier application servers (e.g. Web servers) contain the application's business logic, and perform transactions against back-end databa ...

The database state machine and group communication issues

Fernando Pedone

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 ...

The Database State Machine Approach

Rachid Guerraoui, André Schiper, Fernando Pedone

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 ...

Evaporation de mélanges d’ammoniac et d’huile dans des tubes.

John Richard Thome, Daniel Favrat, Olivier Zürcher

After an experimental study of refrigerants HFC-134a, HCFC-123, HFC- 404A and HFC-407C, and considerable modifications to the test stand, LENI has undertaken a new experimental program and has assembled a large new database for evaporation of ammonia and t ...

Transaction model vs Virtual Synchrony model: bridging the gap

Rachid Guerraoui, André Schiper

Two important models for building fault-tolerant applications have been independently proposed in the literature, the {\em transaction} model (developed within the context of database applications) and the {\em virtual synchrony} model (proposed initially ...

ERC+: an object + Relationship Environment for Database Applications

Stefano Spaccapietra, Christine Parent

The concepts of object oriented data models aim towards modeling of application objects close to the user's view. Yet developers of applications relying on object oriented database management systems are facing problems resulting from the limitations of ob ...
