    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: 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: This application discloses a packet transmission method, a network device, and a system. After receiving a first packet, a first network device obtains a tunnel header corresponding to the first packet. The first network device encapsulates a tunnel header in an IPv6 header by encapsulating the IPv6 header in the first packet, to obtain a second packet. The first network device sends the second packet to a second network device, so that the second network device forwards the packet based on the tunnel header included in the IPv6 header. In this application, the IPv6 header is used to carry the tunnel header.

    Abstract: A 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.

    Abstract: This application discloses a VXLAN packet transmission method, a network device, and a system. After receiving a first packet, a first network device obtains a VNI corresponding to the first packet. The first network device encapsulates the VNI in an IPV6 header by encapsulating the IPV6 header in the first packet, to obtain a second packet. The first network device sends the second packet to a second network device, so that the second network device forwards the packet based on the VNI included in the IPV6 header. In this application, the IPV6 header is used to carry the VNI, and no additional UDP header needs to be encapsulated to carry the VNI.
