  • Publication number: 20230006921
    Abstract: A method includes: receiving an uplink data stream packet; determining a resource module used to process the uplink data stream packet and an identifier of the resource module; modifying the uplink data stream packet based on the identifier of the resource module; and forwarding a modified uplink data stream packet. After a downlink data stream packet is received, a resource module used to process the downlink data stream packet is determined based on an identifier of a resource module in the downlink data stream packet, where the identifier of the resource module in the downlink data stream packet is added after learning the identifier of the resource module in the uplink data stream packet. In this method, the uplink and downlink data stream packets are transmitted by using a same resource module, so that a success rate of communication transmission is effectively improved.

  • Patent number: 11411858
    Abstract: This application provides a method for updating a route in a network. The first network device sends a first LSA packet to a third network device, so that the third network device generates a first route whose destination address is a second IP address, where a next-hop IP address of the first route is the IP address of the first network device, and the second IP address belongs to the IP network segment corresponding to the first IP address which is an IP address of the first network device. The first network device sends a second LSA packet to the third network device when determining that switching needs to be performed on a next hop of a route in the third network device, whose destination address belongs to the IP network segment, and whose next-hop IP address is the first IP address.
