Abstract
A packet tunneling method, a switching device, and a control device are provided. The method includes: a switching device receives 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; determines 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, and tunnels the first packet according to the tunnel flow table entry. 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.
