  • Publication number: 20220182315
    Abstract: A service packet transmission method includes: A control device delivers respective attribute information of at least two transmission paths to a first forwarding device. In this way, after obtaining traffic requirement information, the first forwarding device may determine, based on the traffic requirement information and the respective attribute information of the transmission paths, a first transmission path that meets a traffic requirement. Then, the first transmission path sends a received service packet to a second forwarding device through the first transmission path.

  • Patent number: 11356708
    Abstract: Cross-plane filtering may be used to restore blurred edges and/or textures in one or both chroma planes using information from a corresponding luma plane. Adaptive cross-plane filters may be implemented. Cross-plane filter coefficients may be quantized and/or signaled such that overhead in a bitstream minimizes performance degradation. Cross-plane filtering may be applied to select regions of a video image (e.g., to edge areas). Cross-plane filters may be implemented in single-layer video coding systems and/or multi-layer video coding systems.

  • Publication number: 20220141120
    Abstract: This application provides a forwarding path determining method and an apparatus. In determining a forwarding path, a second network device sends a routing update message to a first network device, where the routing update message carries a first identifier list, the first identifier list includes a binding segment identifier, and the first identifier list indicates a first forwarding path that is from the second network device to a third network device. By using the method, a second forwarding path from the first network device to the third network device is determined. According to the method provided in this application, when there is no controller or controllers cannot communicate with each other, routing advertisement of the binding end identifier is implemented, to determine a forwarding path. This helps simplify a packet forwarding control process.

  • Publication number: 20220131791
    Abstract: This application describes a data transmission method, a network node, and a storage medium for communications technologies. In this application, an underlay segment identifier corresponding to an underlay path is designed, and the underlay segment identifier is advertised, so that a node on a segment routing network can sense the underlay path by using the underlay segment identifier. In this way, when a data packet is transmitted, the data packet can be sent based on an underlay segment identifier carried in the data packet and through an underlay path corresponding to the underlay segment identifier. Therefore, an underlay path through which a data packet is to be transmitted may be specified based on a service requirement, so that different data packets can be transmitted through different underlay paths, thereby improving flexibility and facilitating traffic planning.

    Abstract: A packet forwarding method includes a head node that receives a segment identifier from a second network device. The segment identifier indicates that the second network device can provide a first forwarding path from the second network device to a network device in the first domain. After obtaining a packet, the first network device generates, based on the segment identifier, a segment identifier list corresponding to a second forwarding path that is used to forward the packet and that passes through the first domain, and forwards the packet to the second network device based on the segment identifier list. The segment identifier list corresponding to the second forwarding path includes the segment identifier.
