Abstract: A packet of data and a packet-identification value are transmitted to a network device having an identifier. The stored packet-identification value and the identifier are recorded. The stored packet-identification value is then increased and the process repeats. To receive data, an expected identification value is stored in association with the identifier. A packet and a packet-identification value are received from the network device. The identifier and an indication of receipt are stored.

If the received value exceeds the expected value, the stored packet-identification value, the identifier and the received identifier are recorded. Subsequently, the stored expected value is increased. The process repeats. Network devices and systems are described.

Abstract: To enable more precise synchronization of distributed clocks, before a high-level frame is converted to a low-level frame for transmission over a communication network, if the high-level frame includes a certain type of message, it is flagged. The flag is detected during the conversion process, and the time of detection is stored as a transmission timestamp. When a low-level frame is received from the network, it is immediately timestamped with the time of reception. The timestamped frame is then converted to a high-level frame, and if the high-level frame includes the certain type of message, the timestamp is stored as a reception timestamp.
