Abstract: A method of data processing is applied to a communications device including a first sublayer. A physical sublayer is added above a physical coding sublayer (PCS) of a physical layer, and the physical sublayer is connected to media independent interfaces (xMIIs) with different Ethernet rates. Data signals from different media access control clients (MAC) are interleaved using the physical sublayer. Then, a tx_cmd command is used to instruct the PCS to correspondingly encode an xMII signal. Finally, an encoded xMII signal is sent through a port. According to this method, an encoding function of the PCS may continue to be used, to decouple interleaving from encoding and perform the interleaving through an xMII interface. In this case, port channelization can be implemented for ports with multiple rates, and transmission of a high-priority service is ensured when there is an excessively large quantity of service flows in a transmission process.

Abstract: A method for generating a sharp image based on a blurry image is provided. The method includes acquiring pixel values of pixels in the blurry image, and a convolution kernel of the blurry image, determining a deconvolution kernel of the blurry image based on a preset image gradient operator and the convolution kernel, determining pixel values of pixels in the sharp image based on the deconvolution kernel and the pixel values of the pixels in the blurry image, and generating the sharp image based on the pixel values of the pixels in the sharp image. A deconvolution kernel in the embodiments of the present disclosure is determined based on a gradient operator and a convolution kernel, in other words, the deconvolution kernel introduces the gradient operator as a regularization constraint, which prevents noise from affecting an image recovery process, and improves the quality of a recovered sharp image.

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: A packet processing method includes, when data at a first location in a packet arrives at a channel forwarding layer, determining a first multiframe used to bear the data at the first location, and determining a real timestamp of the first multiframe based on a timestamp of a second multiframe in a channel in which the first multiframe is located. The second multiframe is an Xth multiframe previous to the first multiframe in the channel, X≥0, and the timestamp of the second multiframe is a timestamp at which a second location of the second multiframe arrives at a physical layer such that packet stamping is implemented in the Ethernet leased line technology.
