ORBexpress

ORBexpress, developed by Objective Interface Systems, is a high-performance Object Request Broker designed for real-time, embedded, and distributed systems, providing CORBA-compliant middleware that enables reliable communication across different processors, operating systems, and programming languages. Tailored for developers rather than end-users, the platform relies on an IDL compiler to generate portable, readable code, eliminating the need for manual socket programming and allowing engineers to focus on application logic. Its features include real-time distributed priority inheritance to prevent priority inversion, predictable memory pools for bounded allocation times, quality of service controls for latency and jitter, and fault-resilient connections with automatic failover, making it suitable for mission-critical environments. ORBexpress is recognized for its minimal overhead, with performance near direct socket communication, and a compact footprint that can be configured for resource-constrained embedded devices. It integrates seamlessly across heterogeneous environments, supporting Linux, Windows, various RTOS platforms, and interoperating with other CORBA-compliant middleware through IIOP. The software is widely used in military and aerospace applications, high-precision medical devices, financial systems requiring high-frequency trading, and robotics or transportation systems such as autonomous vehicles and rail management.
