  • Patent number: 12231300
    Abstract: A heterogeneous graph learning system generates and analyzes network implementations. The heterogeneous graph learning system includes obtaining information describing multiple network implementations including heterogeneous nodes. The heterogeneous graph learning system also includes generating a one-hop graph connecting a particular node of the heterogeneous nodes with a set of related nodes. The one-hop graph connects the particular node with the set of related nodes via corresponding edges. The heterogeneous graph learning system further includes transforming the one-hop graph into a weighted graph based on a Dynamic Meta Path Transformation (DMPT). In the DMPT, each of the corresponding edges connecting the particular node to a corresponding related node among the set of related nodes is associated with a corresponding weight.

  • Publication number: 20240348505
    Abstract: This application relates to a network system, a network packet processing method and apparatus, and a storage medium. The network system includes a controller, a network device, and a terminal device. The terminal device is configured to: when the terminal device accesses a network, send a first packet to a network device connected to the terminal device. The network device is configured to: in response to the first packet sent by the terminal device, mark a connection type of a port connected to the terminal device as a first type; and in response to a topology query request sent by the controller, send a topology query response to the controller, where the topology query response includes an identifier or port information of the network device. According to embodiments of this application, network topology discovery performance can be improved.

  • Publication number: 20240297840
    Abstract: Embodiments of this application disclose a packet processing system and method, to perform network topology discovery and routing table delivery. The system includes a source node, an intermediate node, and a destination node. After receiving, from a first port, a first packet to be sent by the source node to the destination node, the intermediate node decodes the first packet to obtain a forwarding path of the packet and an identifier ID of the source node; and the intermediate node generates a first mapping relationship based on the ID of the source node and an identifier of the first port, so that when receiving a response packet of the first packet, the intermediate node may determine a sending port of the response packet based on the first mapping relationship.
