Title: THAP005

Research Question: How effective are advanced CORBA services in control systems?

Methodology: The study used the Common Object Request Broker Architecture (CORBA) for control systems. It specifically examined the interface repository, implementation repository, naming service, property service, telecom log service, and notify service from various vendors. The research team used previous CORBA-based control systems like ANKA and the ALMA Common Software for testing and benchmarking.

Results: The study found that the CORBA services were highly effective in improving communication rates, reliability, scalability, and reducing development time. The use of standard CORBA services saved a significant amount of time in developing common types of applications like error logging, alarm messaging, and slow monitoring. The research team also performed benchmarking and scalability tests on the notify service, which showed promising results.

Implications: The use of advanced CORBA services can greatly enhance the performance and reliability of control systems. The study suggests that these services can be beneficial for other control systems, especially for system-wide services like alarm and logging. However, the researchers also noted that the notify service could be a potential bottleneck and single point of failure, requiring careful consideration and optimization.
