  • Network apparatus and clock synchronization method
    Patent number: 10958367
    Abstract: A network apparatus connected with a first clock source and at least one second clock source is provided. The network apparatus includes a system clock, a slave port connected to the first clock source, at least one passive port connected to the at least one second clock source, and a processor that controls synchronization of the system clock. The processor determines, from the slave port, a first clock offset between the system clock and a clock of the first clock source. The processor determines, from the at least one passive port, at least one second clock offset between the system clock and at least one clock of the at least one second clock source. The processor determines a true clock offset based on the first clock offset and the at least one second clock offset and synchronizes the system clock using the true clock offset.
