Abstract: A label management method, a data stream processing method, and a device, where the label management method includes allocating, by a controller, a source label to a data stream, sending, by the controller, a first Border Gateway Protocol (BGP) update packet to an ingress network device on a label switching path (LSP) of the data stream, and sending a second BGP update packet to an egress network device on the LSP of the data stream, where the first BGP update packet includes a stream identifier of the data stream and the source label, and the second BGP update packet includes a mapping relationship between the source label and a source object of the data stream. Hence, configuration, management, and maintenance can be simplified.

Abstract: Embodiments of this application disclose a packet processing system and method, to perform network topology discovery and routing table delivery. The system includes a source node, an intermediate node, and a destination node. After receiving, from a first port, a first packet to be sent by the source node to the destination node, the intermediate node decodes the first packet to obtain a forwarding path of the packet and an identifier ID of the source node; and the intermediate node generates a first mapping relationship based on the ID of the source node and an identifier of the first port, so that when receiving a response packet of the first packet, the intermediate node may determine a sending port of the response packet based on the first mapping relationship.

Abstract: A first network device includes a processor and a memory having instructions stored thereon that, when executed by the processor, cause the first network device to: obtain a first virtual private network (VPN) route sent by a second network device. The first VPN route includes first identification information that uniquely identifies a first VPN instance in the second network device. The first network device is also caused to generate a second VPN route according to a second VPN instance accessing a third network device and the first VPN route. The second VPN route carries second identification information and routing information of the first VPN route. The second identification information uniquely identifies the second VPN instance in the third network device. The first identification information is different from the second identification information. The first network device is further caused to send the second VPN route to the third network device.

Abstract: A first network device includes a processor and a memory having computer readable instructions stored thereon that, when executed by the processor, cause the first network device to obtain a Flow Specification (FlowSpec) rule with redirect indication information. The redirect indication information includes identification information identifying a first virtual private network (VPN) instance configured on a second network device. The indication information also includes instructions for the second network device to redirect data stream matching the FlowSpec rule to the first VPN instance. The first network device is also caused to advertise the FlowSpec rule with the redirect indication information to the second network device.

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.
