NASA Langley Research Center in Hampton, VA solicits interest from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use.
Synchronization and coordination algorithms are part of distributed computer systems. Clock synchronization algorithms are essential for managing the use of resources and controlling communication in a distributed system. Also, a fundamental criterion in the design of a robust distributed system is to provide the capability of tolerating and potentially recovering from failures that are not predictable in advance. Overcoming such failures is most suitably addressed by tolerating Byzantine faults. A Byzantine-fault model encompasses all unexpected failures, including transient ones, within the limitations of the maximum number of faults at a given time. NASA Langley Research Center has developed a protocol for clock synchronization in the presence of Byzantine faults after a transient event has dissipated. In the presence of arbitrary faulty node(s), the method is proven to self-stabilize the clock. The protocol has been shown to tolerate bursts of transient failures and deterministically unite with respect to synchronization period. The innovative protocol’s timing measures of variables are based on the node’s local clock, and thus, no central clock or externally generated pulse is needed. The protocol produces strong results because it does not rely on any assumptions regarding the initial state or internal status of the system. The minimum assumption enables the protocol to be employed for many practical as well as theoretical applications. NASA is seeking development partners and potential licensees for the patented protocol.
