Abstract: Embodiments of the present disclosure provide a resource allocation method, a packet communication method, and an apparatus. The resource allocation method includes: dividing, by a controller, a cloud data center network into multiple independent logical zones; allocating a corresponding tunnel label range to each logical zone; when a virtual network request for allocating a resource to a tenant is received, searching the logical zones to obtain a logical zone that meets the virtual network request; and allocating a tunnel label to the tenant according to a tunnel label range corresponding to the logical zone that meets the virtual network request. Because each logical zone is independent, during tunnel label range allocation, a same tunnel label range can be allocated to different logical zones. In this way, a same tunnel label can be allocated to different switches in different logical zones, implementing reuse of the tunnel label.

Abstract: A network flow information collection method and apparatus. A switching device receives a data packet, and collects network flow information of the data packet according to all flow entries when the data packet passes from an ingress port to an egress port in the switching device. All flow entries when a same network flow data packet passes from the ingress port to the egress port in the switching device are the same, and all flow entries when different network flow data packets pass from the ingress port to the egress port in the switching device are different. That is, all the flow entries passed from the ingress port to the egress port can uniquely identify one network flow. Therefore, each piece of the network flow information forwarded by the switching device can be accurately collected, improving accuracy of collecting network flow information by the switching device.
