Abstract: Embodiments of the present disclosure provide a routing control method, network device, and controller. The method may include the network device obtaining a route suppression request. The method may also include determining the second routing entry. Furthermore, the method may include setting a state of the second routing entry to a non-delivery state that is used to indicate that the second routing entry does not need to be delivered to a forwarding table. In the method, the network device may have a first routing entry and a second routing entry, an address prefix of the first routing entry is a first address prefix, an address prefix of the second routing entry is a second address prefix, a network segment to which the second address prefix belongs is a subset of a network segment to which the first address prefix belongs, and a mask in the second address prefix is greater than a mask in the first address prefix.

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.

Abstract: A service function chaining (SFC)-based packet forwarding method, an apparatus, and a system, where the packet forwarding method includes receiving, by a first service function forwarding node, a packet forwarding rule from a control node, where the packet forwarding rule indicating a mapping relationship between a match item of traffic characteristic information of a packet and route prefix information, receiving, by the first service function forwarding node, a first packet, where a header of the first packet carries traffic characteristic information of the first packet, determining, by the first service function forwarding node based on the packet forwarding rule, target route prefix information corresponding to the traffic characteristic information of the first packet, determining, by the first service function forwarding node, target next-hop information based on the target route prefix information, and forwarding the first packet based on the target next-hop information.
