Abstract: Embodiments of the present invention disclose a service multiplexing method. The method includes: sending, by a sending device, a bit block stream of a first service to a receiving device; if the sending device determines to switch from the first service to a second service for service sending, sending, by the sending device, at least one service switching indication bit block to the receiving device; and sending, by the sending device, a bit block stream of the second service to the receiving device. In addition, a service switching indication bit block is inserted between bit block streams that require service switching, to perform service switching, thereby reducing a latency and jitter in a service switching process, and ensuring a low latency during service switching.

Abstract: The present disclosure relates to flexible-Ethernet data processing methods and devices. One example method includes acquiring a to-be-switched first client service flow, where the first client service flow is a service flow suitable for transmission on a flexible Ethernet, performing first rate adaptation from a source clock domain to a target clock domain on the first client service flow to obtain a second client service flow that matches the target clock domain, and performing serial-to-parallel conversion on the second client service flow in the target clock domain to obtain a parallel client slot flow.

Abstract: The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for indicating a fault in flexible Ethernet. The method for indicating a fault includes: detecting whether a fault occurs in at least one physical layer entity included in a flexible Ethernet group; and when a fault occurs in the at least one physical layer entity, periodically sending a fault indication code block to a flexible Ethernet client corresponding to the at least one physical layer entity in which the fault occurs. Compared to the prior art, in the technical solutions provided in the embodiments of the present invention, not all bandwidth of a downstream transmission path in the flexible Ethernet is occupied, and data transmission on a non-faulty channel in a same flexible Ethernet group is not affected, thereby reducing a quantity of affected flexible Ethernet clients.
