Abstract: A method for forwarding a packet in a network. The network includes a first network node, a second network node, and a third network node. The method is applied to the first network node, and the method includes: generating a correspondence between a first segment identifier (SID) and a second SID, where the first SID is an identifier that corresponds to the private network, and the second SID is an SID of the third network node; receiving a first packet whose destination address is the first SID; and when it is determined that the second network node is unreachable, pushing the second SID into the first packet to generate a packet, and sending the packet to the third network node.

Abstract: Embodiments of this application provide a packet forwarding method, a route sending and receiving method, and related apparatus. The method is applied to a data center in a non-uniform memory access (NUMA) architecture. The data center includes a server and a network device, and the server includes a first NUMA node and a second NUMA node. The method includes: The first interface processing unit (IPU) receives a first packet from the network device, where the first packet is a packet to be sent to the first virtual machine in the first NUMA node. The first IPU sends the first packet to the first virtual machine. The second IPU receives a second packet from the network device, where the second packet is a packet to be sent to the second virtual machine in the second NUMA node. The second IPU sends the second packet to the second virtual machine.

Abstract: This application discloses a service packet forwarding method, an apparatus, and a computer storage medium. In the method, when receiving a packet sent by any second virtual resource module connected to a first SFF, the first SFF dynamically determines a forwarding path of the packet based on configuration information of a second virtual resource module for implementing a second service function, to implement dynamic load balancing on the packet instead of uniformly performing load balancing by a service function chain ingress node, so as to reduce pressure on the service function chain ingress node.

Abstract: The present disclosure provides a method, an apparatus, and a system for collecting an access control list. A second network device receives a first LSA packet flooded by a first network device, where the first LSA packet includes a first network device identifier and first ACL information, and the first network device and the second network device belong to a same IGP area; and sends an extended first BGP-LS packet to a controller, where the extended first BGP-LS packet includes the first network device identifier and the first ACL information, so that the controller can collect ACL information of the first network device and manage the ACL information of the first network device.
