Abstract: This disclosure relates to a data transmission method, apparatus, and system, and belongs to the field of communications technologies. The data transmission method includes: obtaining, by a first node, m (m≥2) first FlexE clients, mapping the m first FlexE clients to one second FlexE client, and transmitting data of the second FlexE client to a second node, where data of each first FlexE client occupies a fixed timeslot of the second FlexE client, and the second node is different from the first node. In this disclosure, a problem in a related technology that a relatively fine granularity of a FlexE client imposes a relatively strict requirement on data processing performance of a node is resolved, and a plurality of first FlexE clients are mapped to one second FlexE client.

Abstract: The present disclosure relates to a service sending method and apparatus, and a service receiving method and apparatus. One example service sending method includes obtaining, by a network device, a first data stream and a second data stream, and inserting the first data stream into the second data stream to generate a third data stream. The third data stream includes a first information block and a second information block, the first information block is used to carry the first data stream, the second information block is used to carry a first data stream distribution indication map, the first data stream distribution indication map is used to indicate a location of the first information block, and the second information block is identified by using a preset map block type.

Abstract: This application discloses a data forwarding method and device. The method includes: obtaining a first data unit sequence stream by using a first logical ingress port, where the first data unit sequence stream includes at least one first data unit; determining, according to a preconfigured mapping relationship between at least one logical ingress port and at least one logical egress port, a first logical egress port corresponding to the first logical ingress port, where the at least one logical ingress port includes the first logical ingress port; adjusting a quantity of idle units in the first data unit sequence stream, so that a rate of an adjusted first data unit sequence stream matches a rate of the first logical egress port; and sending the adjusted first data unit sequence stream by using the first logical egress port.
