FCS/nORB

Feedback Scheduling Service in ORB Middleware for Networked Embedded Systems

FCS/nORB integrates a Feedback Control real-time Scheduling (FCS) service with the nORB small-footprint real-time Object Request Broker (ORB) middleware designed for networked embedded systems. Existing real-time ORB middleware standards such as RT-CORBA do not adequately address the challenges of

  • providing robust performance guarantees portably across different platforms, and
  • managing unpredictable workload.

The goal of FCS/nORB is providing a middleware platform that enables real-time applications to be truly portable in terms of real-time performance as well as functionality, without the need for hand tuning. The current FCS/nORB (v1.0) features analytically designed feedback control loops that provide real-time performance guarantees by automatically adjusting the rate of remote method invocations transparently to an application.
