Abstract: 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.

Abstract: This application discloses a packet transmission method, a proxy node, and a storage medium, and pertains to the field of communications technologies. According to the method, a new SID with a bypass function is extended for an End.AD SID. Therefore, when receiving a packet that carries the End.AD SID, a local proxy node uses this new SID to transmit an SRH of the packet to a peer proxy node in a bypass manner, so that the peer proxy node can also obtain the SRH of the packet, and therefore the SRH of the packet can be stored in the peer proxy node. In this way, synchronization of the SRH of the packet can be implemented between the two proxy nodes that are dual-homed to a same SF node, so that the SRH of the packet is redundantly backed up.

Abstract: This application discloses a packet transmission method and device. This application provides a method for forwarding a packet to a peer end to restore an SRH. A new SID with a bypass function is extended for an End.AD SID, so that when a local proxy node fails to find the SRH from a local cache, the new SID and control information used to indicate to restore the SRH are carried in the packet whose SRH needs to be restored. The packet is transmitted to a peer proxy node by using the new SID, to indicate the peer proxy node to replace the local proxy node to restore the SRH. In this way, the SRH corresponding to the packet can be restored through the peer proxy node, and then the packet can continue to be forwarded in a network by using the SRH.

Abstract: A packet transmission method includes: receiving, by a first network device, a first packet sent by a previous-hop device of the first network device, where the first packet includes an SR header; generating, by the first network device, cache index information of the SR header, and storing the cache index information and the SR header; generating, by the first network device, a second packet based on the first packet, where the second packet includes the cache index information but does not include the SR header; and sending, by the first network device, the second packet to a second network device.

Abstract: A packet processing method and apparatus, and system. When receiving a packet in an SR encapsulation format, an SFF modifies the encapsulation format of the packet, encapsulates an IP header in the packet in an outer layer of an SR header, and sends a modified packet to an SF. In a process in which the packet is forwarded from the SFF to the SF, the packet still carries the SR header. Therefore, when the packet is subsequently returned from the SF to the SFF, the SFF can restore the original SR encapsulation format by using the SR header carried in the packet.

The method includes: receiving, by a first device, a packet that is sent by a second device and that is used to discover a forwarding path; searching, by the first device based on a first forwarding entry of a data plane, for forwarding information used to forward the packet; and sending, by the first device, path information to the second device based on a second forwarding entry of an autonomic control plane virtual routing and forwarding (ACP VRF) instance, where the first forwarding entry and the second forwarding entry are isolated from each other. In the embodiments, the first forwarding entry and the second forwarding entry are isolated from each other, and returning of the path information is not affected by a data plane fault.

Abstract: This application provides a network configuration method, a device, and a system. The method implemented by a primary device includes: obtaining a configuration template file based on a type of a to-be-configured network device, where the configuration template file corresponds to a network device of a same type and includes at least one configuration command indicating a relationship between a configuration parameter of the to-be-configured network device and a configuration parameter of another network device; generating instantiated configuration data of the to-be-configured network device based on the configuration parameter and the at least one configuration command; and sending the instantiated configuration data to the to-be-configured network device, where the instantiated configuration data is used to instruct the to-be-configured network device to perform configuration based on the instantiated configuration data, to implement configuration automation. This not only improves configuration efficiency of a network device, but also improves configuration accuracy.
