Abstract: This application provides example packet processing methods, network devices, and systems. One example method includes obtaining, by a first network device, a first data communication network (DCN) packet by using a hardware processor, where the first DCN packet is carried in a payload area of a first data frame, and the first DCN packet includes a target device identifier. The first network device determines, based on the target device identifier, by using the hardware processor, whether the first DCN packet is a direct packet. In response to determining that the first DCN packet is a direct packet, the first network device sends the first DCN packet to a second network device, where the second network device corresponds to the target device identifier.

Abstract: This application discloses a communication method and apparatus, which belong to the communication field and are used for data frame transmission. The method is applied to a transit node of a communication system, and the method includes: receiving a data frame, where the data frame includes a bandwidth exclusive channel number, and the data frame is an optical transport network data frame or a microwave data frame; when the bandwidth exclusive channel number carried in the data frame is a preset bandwidth exclusive channel number, obtaining scheduling information and a sink node address from the data frame; and scheduling the data frame based on the scheduling information, and forwarding the data frame to a sink node indicated by the sink node address. In this application, bandwidth utilization of the bandwidth exclusive channel is improved.
