Abstract: The present disclosure provide a method for creating a stream forwarding entry includes: receiving, by a data communication device, a packet; making statistics on the received packet to obtain a statistical value of a stream corresponding to the packet; judging whether the statistical value of the stream exceeds a preset threshold value; and if exceeds the preset threshold value, creating, by the data communication device, a stream forwarding entry for the stream corresponding to the packet, and performing stream forwarding for subsequent packets of the stream according to the stream forwarding entry. Through the present disclosure, the number of stream forwarding entries in a stream table is reduced, the required storage space is reduced, and the maintenance of the stream table is simplified; moreover, the data communication device is not vulnerable to attacks of denial of service and is highly secure.

Abstract: According to a method for handover between distributed access points, an AP 1 receives a handover request sent by a central AP, where the handover request includes an address of a wireless terminal and an identifier of an AP 2; and after receiving the handover request, the AP 1 sends a context handover request to the AP 2, where the context handover request includes an unsent frame of the wireless terminal. In a handover process, the AP 1 may send, to the AP 2, a buffered frame that fails to be sent to the wireless terminal in time, and send the frame to the wireless terminal by using the AP 2, so as to reduce a downlink packet loss when the wireless terminal is handed over between the AP 1 and the AP 2.
