1. US20220069970 - TIME TRANSFER USING PASSIVE TAPPING

Techniques for determining a clock offset between monitoring devices in a network. Such techniques include: obtaining, by a first monitoring device, a first set of network traffic data units sent between a first endpoint and a second endpoint via a first tap on a network link between the first endpoint and second endpoint; obtaining, by a second monitoring device, a second set of network traffic data units sent between the first endpoint and the second endpoint via a second tap on the network link; calculating the clock offset between the first monitoring device and the second monitoring device using the first set of network traffic data units and the second set of network traffic data units; and performing an offset action based on the clock offset.
