- Research Line(s): Timeliness and Adaptation in Dependable Systems (TADS)
- Sponsor: FCT
- Project Number: PRAXIS/P/EEI/14187/1998
- Total award amount: 38.8K Euros
- Coordinator: FCUL
- Partners: FCUL, IST, ISEP, FEUP
- Start Date: Oct. 1999
- Duration: 24 months
- Keywords: Real-Time, Fault-Tolerance, Computer Aided Manufacturing, COTS
- Team at FCUL: 4 researchers, including Paulo Verissimo, Luís Rodrigues, António Casimiro, Pedro Martins
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.
Aims
The DEAR-COTS project will address two main problems:
- How to apply the distributed computing technology to the solution of computer controlled problems using commercial off-the-shelf field-buses?
- How to support inter-working and interconnection of several "field-bus clusters" and the possibility of remotely access these "clusters interface" for supervision and configuration?
Approach and Methods
A structured approach to the first problem needs to address several non-trivial issues, both at the communication and processing levels, such as: the impact of real-time and dependability requirements on the field-bus architecture, distributed fault-tolerant concurrent applications and the real-time support environment.
In order to solve the second problem, the proposal foresees the use of emerging information technologies to cope with heterogeneity issues while providing a dependable user-friendly man-machine interface. This calls for innovative solutions addressing issues such as replica determinism of WWW servers, the use of object oriented technologies, the downloading/uploading within field-bus clusters and ensuring fault-containment between the field-bus and the "open network" domain. The DEAR-COTS proposed architecture will be validated through the development and test of a prototype, which will be integrated in a semi-industrial environment, with stringent safety and timeliness requirements.
Progress and Results
Significant progress has been made during the first project year, namely by defining a suitable DEAR-COTS architecture. Several results have been published and two project workshops have been made. Cooperation among the several teams involved in the project has been carried out with evident success.
