Abstract
A method and an apparatus are provided for determining a network device receiving a first signal and at least one second signal, wherein the first signal carries data to be sent through a first flexible Ethernet interface. A first physical layer clock is determined based on the first signal. A second physical layer clock is determined based on the at least one second signal or the first physical layer clock and the at least one second signal. The first physical layer clock or the second physical layer clock is used as a sending clock of a non-flexible Ethernet interface. The network device includes the first flexible Ethernet interface and the non-flexible Ethernet interface.
Claims20
A method for determining a clock, the method comprising:
- receiving, by a first network device, a first signal and at least one second signal, wherein the first signal carries data to be sent through a first flexible Ethernet interface;
- determining, by the first network device, a first physical layer clock based on the first signal;
- determining, by the first network device, a second physical layer clock based on the at least one second signal or the first physical layer clock and the at least one second signal;
- and
- adopting, by the first network device, the first physical layer clock or the second physical layer clock as a sending clock of a non-flexible Ethernet interface,
- wherein the first network device comprises the first flexible Ethernet interface and the non-flexible Ethernet interface.
An apparatus for determining a clock, the apparatus comprising:
- a processor;
- a memory coupled to the processor and storing program instructions that, upon execution by the processor, cause the apparatus to:
- receive a first signal and at least one second signal, wherein the first signal carries data to be sent through a first flexible Ethernet interface;
- determine a first physical layer clock based on the first signal;
- and
- determine a second physical layer clock based on the at least one second signal or the first physical layer clock and the at least one second signal,
- wherein the first physical layer clock or the second physical layer clock is used adopted as a sending clock of a non-flexible Ethernet interface, and
- wherein the apparatus comprises the first flexible Ethernet interface and the non-flexible Ethernet interface.
A non-transitory computer-readable storage medium storing a computer program, wherein upon the computer program being executed by a computer, a method for determining a clock is implemented, the method comprising:
- receiving, a first signal and at least one second signal, wherein the first signal carries data to be sent through a first flexible Ethernet interface;
- determining, a first physical layer clock based on the first signal;
- determining, a second physical layer clock based on the at least one second signal or the first physical layer clock and the at least one second signal;
- and
- adopting, the first physical layer clock or the second physical layer clock as a sending clock of a non-flexible Ethernet interface,
- wherein a first network device comprises the first flexible Ethernet interface and the non-flexible Ethernet interface.
