  • Patent number: 11855887
    Abstract: A data flow redirection method to overcome a disadvantage that a quantity of adjustable data flows is relatively small due to limited space of a flow specification forwarding table. The method includes receiving, by a network device, a control message sent by a control device, where the control message carries redirection routing information of a data flow and a redirection routing indication, the redirection routing indication instructing to convert the redirection routing information of the data flow into a forwarding entry in a target forwarding table, and tablespace of the target forwarding table is greater than tablespace of a flow specification forwarding table of the network device, and converting, by the network device, the redirection routing information of the data flow into the forwarding entry in the target forwarding table according to the redirection routing indication.

  • Publication number: 20230179523
    Abstract: A packet processing method and apparatus, and a related device, the method including generating, by a first device, a flow filtering rule, where the flow filtering rule includes a match item and an action item, and where the match item comprises an Internet Protocol (IP) address and an autonomous domain identifier, and sending, by the first device, the flow filtering rule to a second device, where the action item is used to instruct the second device to process, based on a packet processing mode indicated by the action item, a packet matching the match item.

  • Publication number: 20220417153
    Abstract: A method, a network device, and a system for delivering a message used for RPD are disclosed. In the solution provided in this application, a second network device may deliver a message used for route policy distribution (RPD) to a first network device. The message includes a route policy including a match condition field and an action field. When detecting that route information of a border gateway protocol (BGP) route matches a target feature carried in the match condition field, the first network device may automatically update a route attribute of the BGP route based on a route attribute carried in the action field. The first network device may automatically update the route attribute of the BGP route according to the route policy included in the message delivered by the second network device, and operation and maintenance personnel does not need to perform manual configuration.

  • Publication number: 20220255862
    Abstract: This application provides a packet forwarding method, a device, a storage medium, and a system. A match condition and a path parameter are carried in a control message, and the path parameter includes an address identifier and a path feature identifier, so that when there are a plurality of forwarding paths between two devices in a network and when a first device receives a packet that meets the match condition in the control message, the packet may be forwarded on a forwarding path corresponding to the path parameter. The method provided in this application helps reduce network configuration complexity.
