    Abstract: The disclosure application discloses a method. The method includes: determining, by a control node, routing entry information of a service function forwarding node in a SFP in the SFC, where the routing entry information records a mapping relationship between route prefix information and next hop information, the route prefix information includes a SPI and a SI, the SPI is used to identify the SFP, the SI is used to identify a location of the service function forwarding node in the SFP, and the next hop information is used to indicate a next hop node of the service function forwarding node in the SFP; and sending, by the control node, the routing entry information to the service function forwarding node, where the routing entry information is used by the service function forwarding node to generate a forwarding table used to instruct the service function forwarding node to forward a packet.

    Abstract: Embodiments of the present invention disclose a path determining method, apparatus, and system. In a hybrid network including one controller for implementing a control function, the controller may separately obtain network topology information of a first network and a second network of different network types by using a same control channel protocol. When the controller obtains a path determining requirement for the data transmission path, because the controller has the network topology information of the first network and the second network, during computation of the data transmission path, the controller can determine a path computation result including transmission path parts of the first network and the second network, without performing additional information exchange with another device, and send the path computation result to the first network device. In this way, planning efficiency of the data transmission path is improved.

    Abstract: The present disclosure discloses a method and an apparatus for implementing load sharing. The method includes: for a congested first link on a first forwarding node, selecting, by a network device, a packet flow forwarded by using the first link; selecting a second link that may be used to forward the packet flow and that is not congested after available bandwidth of the second link is occupied by the packet flow, where the second link is a link between the first forwarding node and a second forwarding node; selecting a first hash gene corresponding to the second link; determining that a third link is not in a congested state after available bandwidth of the third link is occupied by the packet flow; and saving the first hash gene in a source node of the packet flow, where the third link is a link that is on the second forwarding node.

    Abstract: The present disclosure discloses a packet processing method, device, and system. The system includes: a controller, configured to: allocate a service label to a service processing manner of an FEC, establish a mapping relationship between the service label and the service processing manner, send the service label to a source node, and send the mapping relationship to a destination node; the source node, configured to: receive the service label sent by the controller, receive a first packet, insert the service label to the first packet to obtain a second packet, and send the second packet to the destination node; the destination node, configured to: receive the mapping relationship sent by the controller, receive the second packet sent by the source node, and pop the service label from the second packet according to the mapping relationship, to obtain the first packet.
