Abstract: A network of computing devices includes a timing reference, a free-run node, and an aggregator. The reference calculates a first communication packet having a reference timestamp and reference data, and transmits the first packet to the free-run node. The free-run node receives the first packet from the timing reference, calculates a second packet having metadata that includes the reference timestamp, a sparse hash value calculated from the reference data, and a free-run node timestamp, and publishes the second packet to the aggregator. The aggregator receives the second packet and calculates a compensation value from the reference timestamp, the sparse hash value, and the free-run node timestamp. Computer-implemented methods include the free-run node receiving the compensation value and updating its local dock based on the compensation value. Other methods include the aggregator determining an optimal packet path through a network of computing devices based on the metadata.
