Abstract: A controller receives an access request message of a to-be-served flow that is sent by a network device. The access request message includes an identifier of the to-be-served flow and an identifier of a terminal that sends the to-be-served flow. The controller determines service level information of the to-be-served flow based on the identifier of the terminal and the identifier of the to-be-served flow. The controller determines a transmission path of the to-be-served flow and a transmission path of a being-served flow based on the service level information of the to-be-served flow and service level information of the being-served flow. The controller publishes the transmission path of the to-be-served flow and the transmission path of the being-served flow to the network device.

Abstract: An embodiment provides a packet transmission method and apparatus, to resolve a problem that occurs when a packet cannot traverse a NAT device when VTEPs communicate with each other through the NAT device. The method is applied to a VXLAN including a first VTEP, a second VTEP, and a NAT device. The method includes: performing, by the first VTEP, VXLAN encapsulation on a first packet, obtaining a second packet; sending, by the first VTEP, the second packet to the second VTEP through the NAT device; and performing, by the second VTEP, VXLAN decapsulation on the received second packet, to obtain the first packet. The first packet is a packet to be sent by the first VTEP, a destination port number of the second packet is obtained based on a destination IP address of the second packet, and a source port number of the second packet is a preset port number.

Abstract: Embodiments of this application provide a resource obtaining method. A server side obtains a resource request that includes information about a resource requested by the server side. The server side sends the resource request to a client. After receiving the resource request, the client obtains, according to the information about the resource requested by the server side, information about a resource allocated to the server side. The client sends, to the server side, a resource response that includes the information about the resource allocated to the server side. In the method provided in the embodiments of this application, the server side actively sends, to the client, the resource request used to request the resource, and the resource that is allocated by the client to the server side according to the resource request of the server side can better meet an actual requirement of the server side.
