The Reliable Optical Bus (ROBUS) is the core communication system of the Scalable Processor-Independent Design for Enhanced Reliability (SPIDER), a general-purpose fault-tolerant integrated modular architecture currently under development at NASA Langley Research Center. ROBUS is a time-division multiple access (TDMA) broadcast communication system with medium access control by means of time-indexed communication schedule. ROBUS-2 is a developmental version of the ROBUS providing guaranteed fault-tolerant services to the attached processing elements (PEs), in the presence of a bounded number of faults.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "http://ti.arc.nasa.gov/m/opensource/downloads/robus2.zip", "format": "application/x-zip", "mediaType": "application/x-zip"}], "identifier": "OCIO-Fitara-136", "issued": "2015-01-07", "keyword": ["fault-tolerant", "processing-elements", "robus", "robus-2", "rpp", "spider", "tdma"], "landingPage": "http://ti.arc.nasa.gov/opensource/projects/robus-2/", "modified": "2025-03-31", "programCode": ["026:046"], "publisher": {"@type": "org:Organization", "name": "Ames Research Center"}, "theme": ["Management/Operations"], "title": "ARC Code TI: ROBUS-2"}
