Abstract :
We describe the design and implementation of a static real-time data distribution mechanism that uses a real-time event service and a real-time scheduling service to ensure the ontime, and temporally valid delivery of data. The mechanism implements an algorithm, called the just-in-time data distribution algorithm to determine scheduling parameters that will ensure that data that arrives at a requesting target is valid. We use a navy weapons alignment application to demonstrate the necessity and usefulness of the algorithm and implementation. We also present results of tests that demonstrate that our implementation fulfills the guarantees predicted by the theoretical results.
