IndiQoS: Quality of service in indirect communication systems by admin — last modified 2004-12-23 02:44 PM
The project intends to study the development of indirect communication systems of the publish/subscrib type with quality of service parameters support.
StrongRep: Strongly Consistent Replicated Databases for Geographically Large-Scale Systems by admin — last modified 2004-12-23 02:50 PM
The project proposes to address the problem of maintaining strongly-consistent replicated data in a large-scale setting. To achieve this goal, the project intends to combine the recent research of replication management with broadcast protocols optimized for large-scale operation. The project, departs from recent efforts to implement and optimize topology-aware broadcast algorithms, as well as semantically reliable algorithms and intends to configure and tune them in the specific application area of database replication. It is expected that the novel combination of these approaches can result in a solution that exhibits enough performance to sustain the management of the critical application data that strictly requires strong consistency.
RUMOR: Probabilistic Semantically Reliable Protocols by admin — last modified 2004-12-23 02:47 PM
In recent years, two orthogonal promising approaches to improve the scalability of multicast protocols have emerged. One is the use of probabilistic epidemic protocols. These protocols support the efficient dissemination of data among a large number of nodes providing probabilistic guarantee of delivery. The other is the use of semantic knowledge to support higher sustained throughput in groups with heterogeneous performance behavior. The Rumor project intends to conduct research in order to integrate both approaches in a single efficient large-scale multicast protocol. All large-scale applications that require the multicast of messages from a large number of members and that exhibit some degree of message obsolescence can potentially benefit from the results of this project.
GLOBDATA: An efficient software tool for global data access by admin — last modified 2007-07-11 11:52 AM
The overall objective of the project is to design an efficient software development tool and support system to provide application developers with a global view of an object database repository with transactional access to geographically distributed persistent objects independent of their location.
MOOSCo: Multi-user Object Oriented environments with Separation of Concerns by admin — last modified 2005-02-21 06:58 PM
The MOOSCo project, Multi-user Object-Oriented environments with Separation of Concerns, addresses the difficulties in applying a component-based approach in a vertical and integrated manner, from analysis to implementation, to the design of this class of systems. The project will define an architecture that will be applied in the MOOs context. MOO environments constitute a challenge for object-oriented distributed systems theory and practice due to its unique requirements for dependability, scalability, adaptability, usability, dynamic changes, non-functional domains to be considered, and efficiency.
SHIFT: Group Communication with Differetiated Messages by admin — last modified 2005-02-21 07:03 PM
The project intends to study the use of knowledge on the application semantics to improve the efficiency of group communication systems. The starting point of the project is the definition of semantic reliability, recently introduced by the project partners.
SemP2P by admin — last modified 2005-02-21 07:11 PM
Semantically Reliable Multicast Protocol for Peer-to-Peer Communication in Multi-User Games.
TOPCOM: Topology-Aware Reliable Group Communication in Geographically Large-Scale Systems by admin — last modified 2005-03-14 04:12 PM
The goal of the project is twofold: in first place, it intends to implement and test a mature distribution of the Navigators' protocols and, in second place, to contribute to the validation the Ensemble framework. Since there are several technical differences between the protocol designed by the Navigators group and the protocols currently implemented in Ensemble, this experiment will emphasize the generic aspects of the framework and reveal its potential limitations. The project will gather feedback from protocol implementors in order to improve the framework and, hopefully, to support other research groups in adopting Ensemble for their projects.
DEAR-COTS: Distributed Embedded Architectures using Commercial Off-The-Shelf Components by admin — last modified 2005-02-21 07:27 PM
The main purpose of the DEAR-COTS project is the specification of an architecture based on the use of commercial off-the-shelf (COTS) components, able to support distributed computer controlled systems where safety and timeliness are major requirements.
