Latest Patents

David B Schwartz holds a patent for "Active failure detection." This invention addresses failures in a fault-tolerant computer system that includes two or more input/output processors connected to a data communication system. The system is designed to detect failures associated with both primary and standby input/output processors by monitoring data communication. It can discriminate between failures of the input/output processors and communication failures within the data communication network itself. The invention employs heartbeat-like transmissions along with various other categories of data communication to effectively detect failures. Notably, the system can identify failures when input/output processors are on a common network segment, as well as when they are on different segments, accommodating the filtering behavior of network elements such as active hubs.
