Application Scenarios for Synchronous Ethernet
In Figure 5-13, devices are connected, and clock synchronization needs to be achieved between upstream and downstream devices.
To ensure reliability of the clock synchronization network, Device1 and Device3 each are connected to an external clock source to import clock signals. During network deployment, each device preferentially traces clock signals transmitted from Device1. When the clock source connected to Device1 is faulty, devices trace clock signals transmitted from Device3.
