RTI Extensions Enable Distributed Real-Time Java

Real Time Innovations (RTI), The Real-Time Middleware Experts, announced that it has added extensions to RTI Data Distribution Service to take advantage of Real-Time Specification for Java (RTSJ)-compliant Java Runtime Environments (JREs). With these extensions, developers can take advantage of the real-time messaging capabilities of RTI Data Distribution Service in conjunction with real-time Java programming to develop high-performance and predictable distributed applications.

Java programming provides a structured, safe, well understood and portable development and execution environment. However, adoption of Java development for real-time applications has been limited because commercial JREs have not been able to deliver predictable behavior. RTSJ addresses these limitations by providing developers with many standard real-time capabilities, including priority-based thread scheduling, high-resolution timers and asynchronous event-handlers. RTI Data Distribution Service has been fully integrated with the RTSJ extensions in IBM WebSphere Real Time. Support for other RTSJ implementations is also planned.

“RTI Data Distribution Service takes advantage of the RTSJ extensions in IBM WebSphere Real Time to enable development of distributed real-time Java applications,” said Gerardo Pardo-Castellote, chief technology officer for RTI.

“Developers can leverage Java and its rich ecosystem of tools while achieving timing and response goals consistent with real-time application requirements, even across a distributed system. This capability was previously only available with applications that were native-machine-code compiled, such those written using C, C++ and Ada.”

RTI Data Distribution Service introduces new Quality-of-Service (QoS) configuration parameters that take advantage of RTSJ and IBM WebSphere Real Time. QoS control allows distributed-application developers to fine-tune system behavior in order to optimize performance and memory use.

Price & Availability
RTI’s RTSJ Extensions Kit for RTI Data Distribution Service and IBM WebSphere Real Time is available immediately for Red Hat Enterprise Linux hosts. Pricing begins at $7,200, which includes maintenance and support. RTI Data Distribution Service is licensed separately. It is available today for many operating-system and processor combinations, including Windows, Windows CE and Windows Mobile; Solaris; Linux; LynuxWorks LynxOS; QNX Neutrino; Wind River VxWorks; and Green Hills INTEGRITY configurations. A complete development package for $84,600 USD includes a comprehensive Architecture Study from an RTI expert who will provide written design recommendations based on an evaluation of application requirements, plus two days of customer-specific training, one week of follow-up consulting, and one year of maintenance and support.

About RTI Data Distribution Service
RTI Data Distribution Service (formerly NDDS) is high-performance messaging middleware for the development and integration of applications that require low latency, high throughput, high scalability, deterministic responses and minimal consumption of network, processor and memory resources. RTI Data Distribution Service is an open-architecture platform that complies with the Object Management Group’s (OMG’s) Data Distribution Service (DDS) for Real-Time Systems standard.
