Abstract

For more than one decade, researchers have considered Ethernet as a natural replacement to legacy fieldbuses in modern distributed applications. However, Ethernet components require special modifications and hardware support to provide strict timing guarantees. In general, the high-cost of deploying hardware components limits the experimental validation of proposed solutions in real-world applications. Despite the vast literature, only a few solutions report real implementations, and they are all closed to the research community, hindering further development for constantly evolving applications. This paper introduces Atacama, an on-going effort on deploying the first hardware-accelerated and open-source framework for mixed-criticality communication on multi-hop networks. Specialized modules exploit the principles of traditional fieldbus systems to coordinate communication tasks on real-time stations, and can be easily integrated to and coexist with Commercial Off The Shelf (COTS) devices operating with best-effort traffic. Experimental characterization of implemented prototypes report minimal jitter on 1Gbps links, and show that real-time guarantees are resilient to injected best-effort traffic. The framework is available as an open-source project, enabling researchers to verify the results, explore, test, and deploy new networking solutions for modern distributed systems in real-world scenarios. © 2013 EDAA.
