Design and implementation of communication middleware of heterogeneous processors in STRS system

Abstract

Aiming at the problems of low real-time performance, large redundancy, and inability to recover from faults in the communication between heterogeneous processors in the Space Telecommunication Radio System (STRS),the distributed data distribution service (DDS) middleware technology is introduced into the STRS architecture to realize the publish/subscribe mode-based communication middleware between the STRS heterogeneous processor waveform application components.Under the premise of being fully compatible with the STRS standard specification, it effectively improves the real-time performance of the communication system based on STRS, reduces the complexity and redundancy of the system, improves the development efficiency, saves the development and maintenance costs of the system, and realizes the dynamic refactoring of global and local modules.
