  • Publication number: 20210399959
    Abstract: Methods, systems, and apparatus for network monitoring and analytics are disclosed. The methods, systems, and apparatus for network monitoring and analytics perform highly probable identification of related messages using one or more sparse hash function sets. Highly probable identification of related messages enables a network monitoring and analytics system to trace the trajectory of a message traversing the network and measure the delay for the message between observation points. The sparse hash function value, or identity, enables a network monitoring and analytics system to identify the transit path, transit time, entry point, exit point, and/or other information about individual packets and to identify bottlenecks, broken paths, lost data, and other network analytics by aggregating individual message data.

  • Publication number: 20200220637
    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.

  • Patent number: 9621290
    Abstract: An apparatus and method are described for compensating for frequency and phase variations of electronic components by processing packet delay values. In one embodiment, a packet delay determination module determines packet delay values based on time values associated with a first and a second electronic component. A packet delay selection module selects a subset of the packet delay values based on the maximum frequency drift of the first electronic component. A statistical parameter determination module evaluates a first and a second parameter based on portions of the subset of packet delay values. A validation module validates the parameters when each portion the subset of packet delay values includes a minimum of at least two packet delay values. An adjustment module compensates for at least one of a frequency variation and a phase variation of the first electronic component based on the parameters if the parameters are both validated.
