Embodiment 1
[0034] See figure 1 , figure 1 It is a schematic structural diagram of a time-aware module based on a distributed network provided by an embodiment of the present invention. A time-aware module based on a distributed network, including:
[0035] A synchronization site unit, configured to determine whether the time-aware module is a master clock according to a clock selection algorithm;
[0036] a master clock unit, configured to send time information to the synchronization site unit;
[0037] a slave clock unit for receiving said clock information of said synchronous station unit and sending said clock information to said time-aware application;
[0038] a first port, configured to receive the time information of the synchronization station unit;
[0039] a second port, configured to send the time information to the synchronization site unit;
[0040] The data transfer unit is configured to receive the first packet information sent by the first port, and is also configure...

[0073] A distributed network is formed by the interconnection of node machines distributed in different locations and having multiple terminals. Any point in the network is connected to at least two lines. When any line fails, the communication can be completed through other links, which has high reliability. At the same time, the network is easy to expand.
[0074] Preferably, all nodes in the distributed network constitute a...
