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.

Abstract: This application provides a data transmission method and apparatus, and relates to the field of communications technologies. The method includes: obtaining a plurality of code block streams; distributing, based on a preset multiplexing sequence, code blocks in the plurality of code block streams by slots, to form one code block stream; and segmenting and encapsulating the one code block stream, to generate at least one frame. In this application, a data transmission delay can be reduced.

Abstract: Devices and methods for routing data packets in a communication network from a source node to a destination node via one or more intermediate routing nodes in a privacy-preserving manner are disclosed. The source node is configured to concatenate a first routing vector element including a first bit pattern with an initial routing vector defining a bit string, encrypt the concatenation using a selected first encryption key, and replace a portion of the encrypted initial routing vector at a first position by the encrypted first routing vector element. Moreover, the source node is configured to concatenate a second routing vector element, including a second bit pattern and routing information of the destination node, with the modified routing vector, encrypt the concatenation using a selected second encryption key, and replace a portion of the encrypted modified routing vector at a second position by the encrypted second routing vector element.
