Abstract: A first node communicates with a second node by using a first channel, and the first channel includes N slots. The first node sends first information to the second node, where the first information is used to request to change a correspondence between a first slot in the first channel and a first service, and where the first information includes an identifier of the first service and an identifier of the first slot. The first node receives second information from the second node, where the second information is used to indicate to acknowledge or reject the request in the first information.

Abstract: A communication method includes, when a rate adaptation or a frequency offset adjustment is performed on a first block sequence, a quantity of first preset blocks that are added or deleted is one of one or more preset values. In this way, a receive end may determine, based on whether the quantity of first preset blocks in the received first block sequence is a preset value, whether an exception occurs in the first preset block during transmission. Based on this, a false packet can be accepted as a correct packet less frequently, thereby improving a mean time to false packet acceptance (MTTFPA) indicator.

Abstract: A first communication apparatus determines a first transmission delay indicating a transmission delay of a fine granularity service in the first communication apparatus; and the first communication apparatus sends the first transmission delay to a second communication apparatus. A service bit flow sent by a sink node meets a delay compensation requirement to ensure that a network transmission delay from a source node to the sink node and a network transmission delay from the sink node to the source node in a fine granularity service network are equal or meet an expected error range, or that the network transmission delay from the source node to the sink node and the network transmission delay from the sink node to the source node are adjusted to an expected value to meet a service requirement.

Abstract: A service flow adjustment method and a communication apparatus are provided. Slot adjustment information is carried in a client signal flow sent between nodes, so that times at which all nodes on a network switch slot configuration can be unified, to avoid service damage in a process of adjusting a network transmission bandwidth. The method includes: A first node receives a first client signal flow from a second node by using N slots of a first bundling group; and after first duration starting from a time at which the first node detects slot adjustment information, the first node receives the first client signal flow from the second node by using M slots of the first bundling group.

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.
