摘要： 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.

摘要： A method, an apparatus, and a system for enhancing a concurrent processing capability of a wireless local area network (WLAN) are disclosed. The method includes receiving a first association request including an identifier of a first station (STA) that is from the first STA; performing association with the first STA; sending a first association query request including the identifier of the first STA to a WLAN controller; after the first STA is associated, receiving an association query response from the WLAN controller; and performing disassociation from the first STA when the association query response is used to instruct an access point (AP) not to associate with the first STA. When a large quantity of association events need to be concurrently processed, a STA is associated with at first, improving user experience.

摘要： A method for handover between distributed access points (APs), where the method includes a central AP sending a first instruction to an AP 2. The first instruction includes an identifier of the wireless terminal, and the first instruction is used to instruct the AP 2 to start receiving a data frame from the wireless terminal, and forbid the AP 2 to return an acknowledgement frame to the wireless terminal. The central AP sends a handover success notification message to an AP 1 and the AP 2. The handover success notification message includes the identifier of the wireless terminal, and the handover success notification message is used to instruct the AP 1 to stop receiving the data frame from the wireless terminal, and is used to instruct the AP 2 to return the acknowledgement frame to the wireless terminal.

摘要： A method for a handover between distributed access points is disclosed, including receiving, by a central AP, an Ethernet frame; adding, by the central AP, a sequence number to the frame according to an address of a wireless terminal; sending, by the central AP to an AP 1, the frame to which the sequence number is added, and storing the frame to which the sequence number is added in a historical frame set of the wireless terminal; and sending, by the central AP, a frame in the historical frame set of the wireless terminal to an AP 2 when the wireless terminal is handed over from the AP 1 to the AP 2. If the wireless terminal moves fast, the central AP can send the frame in the historical frame set to the wireless terminal using the AP 2, so that a downlink packet loss is reduced.
