Welcome back to Bristol (UK)!

And thanks for a great event with lots of contacts and good project talks at our SYSGO booth! With nearly 200 people at the event, we definitely had a great time - raising also interest with our joint presentation together with RTI (Real-Time Innovations).

About the Presentation

RCA OCORA: Safe Computing Platform using open Standards

The railway sector is facing a major transition as it moves towards more fully automated systems on both the train and infrastructure side. This in turn, requires the development of appropriate, future-proof connectivity and IT platforms.

The Reference Control Command and Signalling Architecture (RCA) and Open Control Command and Signalling Onboard Reference Architecture (OCORA) have developed a functional architecture for future trackside and onboard functions. The RCA OCORA open Control Command Signalling (CCS) on-board reference architecture introduces a standardized separation of safety-relevant and non-safety-relevant railway applications and the underlying IT platforms. This allows rail operators to decouple the very distinct life cycles of the domains and aggregate multiple railway applications on common IT platforms.

Based on a Safe Computing Platform (SCP), the architecture accommodates a Platform Independent Application Programming Interface (PI API) between safety-relevant railway applications and IT platforms. This approach supports the portability of railway applications among IT platform realisations from different vendors.

Two of its authors will discuss the RCA OCORA architecture with emphasis on its safe computing framework. The talk will review the required operating system standards and the discuss the newly-released DDS Reference Implementation for Safe Computing Platform Messaging. While designed for rail, this architecture will have elements of interest for other industries.

About the HIS

The HIS (High Integrity Software) Conference brings together software engineers and industrial and academic specialists with their knowledge sharing challenges, best practices and experience. Topics this year were critical software-intense systems, cyber-physical system architectures, software development lifecycles and verification techniques that will impact defect rates and maintainability. 

The aim of the High Integrity Software conference is to share the experience and know-how that will address these challenges within our industry and help to build the foundations of a trustworthy software ecosystem for the future.
