Example Embodiment
[0057] Example 1
[0058] Based on the design principle of the present invention, this embodiment proposes a method of monitoring network time synchronization performance, including the PTP interface unicast multi-server monitoring process and NTP interface unicast multiple server monitoring processes;
[0059] (1) PTP interface unicast multi-server monitoring process
[0060] In PTP Unicast mode, the PTP master is first necessary to establish a connection through the unicast signaling negotiation mechanism, and then the point-to-point single broadcast communication is available. The unicast signaling negotiation mechanism complies with the IEEE 1588 (PTP) standard, the basic process of the PTP unicast signaling negotiation mechanism figure 1 Indicated. According to the IEEE 1588 (PTP) standard, the PTP main clock (MASTER) and PTP are exchanged with the TLV (Type, Length, Value) signaling from the clock (SLAVE) to exchange the unicast mechanism negotiation, used for the TLV signal...
Example Embodiment
[0100] Example 2
[0101] Based on the design principle of the present invention, in order to achieve the method of monitoring network time synchronization performance, the present embodiment proposes a system that monitors network time synchronization performance, such as Figure 4As shown, the system includes a monitoring device and a monitoring data analysis software connected via a network management channel; an NTP / PTP interface monitoring card with a plurality of integrated designs is configured on the monitoring device; NTP / PTP The interface monitoring card is used to implement the PTP interface and the NTP interface and connect multiple monitored PTP time servers and / or monitored NTP time servers; the NTP / PTP interface monitoring card is built into the monitoring of Example 1 In the method of network time synchronization performance, the PTP interface unicast multi-server monitoring process and embedded software in the NTP interface unicast multiple server monitorin...
