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: The embodiments of the present invention provide a tunnel fault detection method and a traffic engineering (TE) node. The method includes: receiving, by a traffic engineering TE node, a link fault report packet; determining, by the node, a faulty link in which a fault occurs according to the link fault report packet; detecting, by the node, whether one or more tunnels which use the node as an ingress node and pass through the faulty link exist; and identifying the tunnels as faulty tunnels if the one or more tunnels which use the node as the ingress node and pass through the faulty link exist. In the embodiments of the present invention, the TE node can detect all faulty tunnels at a time, and it is not necessary to wait until the fault notification based on each tunnel is received and then the faulty tunnel is identified one by one.

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.
