For the Ada Programming Language

High Performance CORBA for Real-time and Embedded Applications

Why ORBexpress RT? Because ORBexpress RT is simply the easiest way for a complex system to communicate to a world full of differences.

You will really appreciate the features of ORBexpress RT if you:

  • Use an embedded operating system, or
  • Want access to transport protocols beyond TCP/IP, or
  • Use the native thread priorities in your operating system, or
  • Want to control and bound the resources used by the ORB, or
  • Want to control the Quality of Service parameters to optimize use of your transport, or
  • Want to build a predictable distributed system.

ABOUT: ORBexpress RT for Ada

ORBexpress® RT is a uniquely powerful communications framework for creating high performance, high-reliability, distributed applications. ORBexpress RT is used for the development of real-time systems, where reliability and predictability are critical. Going beyond the Real-time CORBA Specification, ORBexpress RT provides developers the tools they need to ensure the success of their project.

Developed by real-time experts, ORBexpress RT for Ada internals are designed for maximum performance and predictable behavior. ORBexpress RT for Ada can be used by developers building applications with hard deadlines, such as those found in avionics and process control. These industries require maximum performance and deterministic capabilities and they choose ORBexpress RT for Ada because it offers:

  • Priority propagation reducing inter-system priority inversion problems
  • Fault resilient connections between the client and server allowing clients to choose between multiple paths to servers, enabling the use of redundant networks
  • Replaceable transports allowing developers to “plug-in” predictable custom transports
  • Quality of Service allowing the control of upper bounds on latency and jitter

FEATURES: ORBexpress RT for Ada

  • Fast and Small - Independently recognized as the fastest and smallest ORB on the market. Learn more about ORBexpress performance. ORBexpress also fully supports the new CORBA/e (CORBA for embedded) standard.
  • Keep Your Priorities Straight: The ORBexpress RT Distributed Priority Inheritance™ capability greatly reduces the intersystem priority inversion problems that can plague complex distributed, real-time systems.

    • Distributed Priority Inheritance allows servers to run requests at the client’s priority.
    • The internal algorithms and concurrency primitives in ORBexpress are carefully designed to minimize and bound priority inversions.
  • Specify Quality of Service: ORBexpress provides a universal Quality of Service specification that can parameterize any network transport. Using a QoS parameter, you can maintain upper bounds on latency and jitter, guarantee bandwidth, control buffer sizes, etc.
  • Flexible Transports: Network transport flexibility is essential to optimizing systems performance and hardware resources. ORBexpress RT for Ada provides a number of transport options. ORBexpress RT ships with IIOP (GIOP over TCP/IP), shared memory, and other operating system specific transports. ORBexpress RT for Ada provides transport APIs so that you can write your own transports, enabling unique capabilities in your application.
  • Configurable Resource Usage: While static memory footprint is important, ORB dynamic memory management greatly affects the ability of the ORB to scale in different environments. We offer ORBexpress RT for Ada in several configurations and provide a large number of settable parameters, such as buffer sizes, that allow developers to optimize resource usage according to the application's feature set requirements, memory constraints and messaging traffic.
  • Tested Interoperability: ORBexpress RT for Ada fully supports IIOP™ (Internet Inter-ORB Protocol), the CORBA standard vendor-independent protocol. Through IIOP, ORBexpress RT for Ada offers proven interoperability with other IIOP-compliant ORBs and middleware.
  • Full Multi-Tasking: ORBexpress RT for Ada fully supports multi-tasking distributed applications on all platforms by using the priority-based scheduling capabilities of the Ada run time. In addition, the product has a portable synchronization facility pproviding improved performance.
  • Fast Multiplexing Connection Model: The ORBexpress RT for Ada connection management maintains high performance as the number of objects, operations, and threads are increased. Multiple requests to a server from different threads share the same connection. Requests can be processed in parallel by multiple server threads.
  • Object Portability: ORBexpress RT for Ada enables true application portability. ORBexpress RT for Ada has a fully featured Portable Object Adapter (POA) to ensure portability of object implementations. The ORBexpress IDL™ (Interface Definition Language) compiler generates readable and well formatted Ada code.
  • Optimized Collocation: ORBexpress RT for Ada provides architectural flexibility of complete location transparency, including collocation of objects in the same process. ORBexpress RT for Ada optimizes invocations between collocated objects to a local subprogram call, maximizing performance.
  • Fault Resilient Connections: ORBexpress RT for Ada facilitates fault-resilient connections between a client and server, enabling the development of highlt available systems. Alternate paths to a server can be established. On failure to establish a connection or failure of an established connection, ORBexpress RT for Ada can retry on the same path, use an alternate path, or fail over to an alternate server.
  • Flexible, Controllable Quality of Service: ORBexpress RT for Ada supports synchronous and asynchronous messaging to provide flexibility for your application. Reliability options allow tuning to your application needs.
