Abstract: A network node for a Data Communication Network (DCN) and a network device for providing traffic to the DCN are provided. The network node is configured to receive a plurality of packets carrying DCN messages; determine, from the received packets, a first set of packets addressed to other network nodes of the DCN. The network node is then configured to forward the first set of packets over a Time-Division-Multiplexing (TDM) connection, in particular over an Optical Data Unit-k (ODUk) connection, to a determined network node of the DCN. According to the application, a high bandwidth efficiency is maintained, and the number of interfaces to be managed on a controller is reduced.

The method includes: a first device obtains a sensing parameter including a physical feature of a sensing target; configures a first frame based on the sensing parameter, and performs sensing on the first frame. The first frame includes M first time periods and N second time periods, both M and N are integers greater than or equal to 0, without being equal to 0 at the same time. The first device sends or receives a waveform of a communication signal during the first time period, and sends or receives a waveform of a sensing signal during the second time period. According to this application, spectral efficiency can be improved as sensing is performed without affecting communication thereby minimizing communication overheads, and sensing and communication occupy a same spectrum resource thereby meeting the requirements of sensing and communication.
