    摘要： A method and an apparatus for managing resources of a network slice are disclosed. In the method, resources are allocated more properly by using a feature that peaks and valleys of load of network slices overlap, so that resources can be coordinated from another network slice whose independent decision result is scale-in or is keeping a quantity of instances unchanged to a network slice whose independent decision result is scale-out, or resources can be coordinated from another network slice whose independent decision result is scale-in to a network slice whose independent decision result is keeping a quantity of instances unchanged, and therefore a network slice whose capacity needs to be increased does not need to request new resources from an infrastructure, thereby improving resource utilization of the infrastructure and reducing resource procurement costs of a slice tenant.

    摘要： A packet tunneling method, a switching device, and a control device are provided. The method includes: receiving, by the switching device, a tunnel flow table entry delivered by the control device, where the tunnel flow table entry is used to determine a to-be-tunneled packet and indicate a tunneling operation to be performed on the to-be-tunneled packet; determining, by the switching device according to the tunnel flow table entry, whether the received first packet is the to-be-tunneled packet; and when the first packet is the to-be-tunneled packet, tunneling, by the switching device, the first packet according to the tunnel flow table entry. According to the embodiments of the present invention, because the switching device supports a tunnel flow table, when a packet is transmitted in a mobile packet network by using the OpenFlow protocol, tunnel encapsulation or decapsulation can be performed on the packet by using the tunnel flow table entry delivered by the control device, thereby enhancing a packet processing capability in the mobile packet network.
