    Abstract: The present invention discloses a service transmission method, a network device, and a network system. The method includes: obtaining, by a first network device, a client service of FlexE, and obtaining clock information corresponding to the client service; mapping, by the first network device, the client service and the clock information to a timeslot of a FlexE frame, where the client service and the clock information occupy a same timeslot and/or different timeslots; and sending, by the first network device, the FlexE frame to a second network device. Therefore, service clock information can be transparently transmitted in flexible Ethernet by using the method of the present invention.
