Abstract: This application discloses a block group loss determining method and an apparatus. The method includes: A transmit end obtains at least two block groups, and sends the at least two block groups to a receive end. The receive end receives the at least two block groups, obtains a receiving quantity of first block groups between a first boundary block group and a second boundary block group in the at least two code groups, then obtains a target quantity of first block groups between the first boundary block group and the second boundary block group, and determines a quantity of lost block groups based on the receiving quantity and the target quantity.

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: A communication method, device, and a storage medium to resolve a problem that information about a clock frequency and a clock phase of a service cannot be correctly transmitted to a receiver or correctly recovered because transparent transmission of the information about the clock frequency and the clock phase of the service cannot be implemented. Because a value of k based on a reference data unit is inserted into a second data flow, and the value of k can indicate a quantity of third data units included between a second data unit and the reference data unit in a first data flow, a receive end device can completely recover the first data flow based on the value of k.

Abstract: A method and an apparatus for transmitting service data are disclosed. In technical solutions of the present disclosure, when an exclusive service does not completely occupy a bandwidth resource allocated to the exclusive service, data transmission of at least two candidate services on an actually unused bandwidth is supported. In this way, a waste of bandwidth resources can be reduced and network utilization can be improved.

Abstract: This application provides an example delay measurement method and an example network device. The method includes receiving, by a first network device, a first service flow. The method also includes determining, by the first network device, a first delay value based on a first measurement code block in the first service flow. The first delay value is a time difference between a first moment at which the first measurement code block is detected in the first network device and a second moment at which the first measurement code block is detected in the first network device.
