This application discloses a service packet forwarding method and related apparatus. In the service packet forwarding method, when receiving a packet sent by any second virtual resource module connected to a first service function forwarder (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 achieve dynamic load balancing on the packet instead of relying on a service function chain ingress node to perform load balancing, so as to reduce pressure on the service function chain ingress node.

Service packet forwarding method, apparatus, and computer storage medium

Embodiments of this application provide a data transmission method and apparatus. The method includes receiving, by a first device, a data packet, and extracting first address information of the data packet, where the first address information indicates a VNF; retrieving, by the first device based on the first address information, an SRv6 tunnel policy that corresponds to the first address information and that is from a SRv6 tunnel list; obtaining, by the first device, a forwarding path corresponding to a first SRv6 VPN SID, where the forwarding path is used as a data transmission path when the first device communicates with a second device corresponding to the first SRv6 VPN SID; and forwarding, by the first device, the data packet to the VNF based on the forwarding path.

Data transmission method and apparatus

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.

Packet forwarding method, route sending and receiving method, and apparatus

A method, an apparatus, and a system for collecting an access control list (ACL), where a second network device receives a first link-state advertisement (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 Interior Gateway Protocol (IGP) area, and sends an extended first Border Gateway Protocol-Link State (BGP-LS) packet to a controller, where the extended first BGP-LS packet includes the first network device identifier and the first ACL information such that the controller can collect ACL information of the first network device and manage the ACL information of the first network device.
