Abstract: A method implemented by a communication apparatus for processing a packet. The method includes obtaining, by the communication apparatus, a first packet, where the first packet includes a first-layer header. The first-layer header includes an identification field used to identify whether the first-layer header of the first packet includes information in a second-layer header. The communication apparatus then processes the first packet, which may include sending the first packet, forwarding the first packet, scheduling or marking the first packet, or the like.

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 subject matter 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. 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.
