It floods, not will lead to Wireless Fidelity interface-free resources occupancy, promote communication quality.
Step 102 judges whether the destinations traffic address is occupied according to first message.
In a step 102, Wireless Fidelity controller can judge that destinations traffic address is according to the first message received
It is no occupied.For example, Wireless Fidelity controller can be in a complete online legal terminal list of internal build, i.e. target
List.The target list includes the mailing address currently occupied by other terminals.Further, which may include
It is address media access control (Media Access Control, MAC) of each online terminal, speed limit specification, requested logical
Believe address and sends the time of mailing address request.
Wireless Fidelity controller can judge whether destinations traffic address is recorded in target list according to the first message.Such as
Fruit destinations traffic address is not recorded in target list, then can determine that destinations traffic address is unoccupied, and can be by mesh
Mark mailing address is added in target list.Further, the MAC Address of the terminal of the first message will can be sent, speed limit is advised
Lattice and the time for sending the first message are added in target list.
If destinations traffic address has been recorded in target list, it can determine that destinations traffic address is occupied.I.e.
The terminal for sending the first message passes through what duplicate address detection (Duplicate Address Detection, DAD) preparation used
Destinations traffic address is clashed with some occupied mailing address of online terminal.
If step 103, the destinations traffic address are occupied, to the unicast media accessing to control address of the terminal
Send the second message that destinations traffic address has occupied.
It in step 103, can be to terminal if Wireless Fidelity controller judges that destinations traffic address is occupied
Unicast media accessing to control address send the second message for having occupied of destinations traffic address.I.e. Wireless Fidelity controller can be with structure
It makes and has occupied (Neighbor Advertisement, NA) message response to just in the terminal of DAD detection.The NA message of construction
Target MAC (Media Access Control) address is the unicast mac address for initiating the terminal of DAD request, rather than purpose multicast IP described in RFC4861 is raw

Communication quality.
Step 202 judges whether first message meets message and receive speed limit condition.
It in step 202, can after Wireless Fidelity controller receives the first message for request target mailing address
Speed limit condition is received to judge whether the first message meets message.It should be noted that WIFI controller is according to being supported most
Big online number of terminals, can calculate under normal circumstances, WIFI controller receives NS message/NA message rate.Therefore, may be used
An empirical value is arranged.If the NS message/NA message rate received is significantly more than this empirical value, so that it may determine
There are malicious peers to carry out NS/NA extensive aggression.Reception limit can be carried out to these messages on the interface for receiving message
Speed protects WIFI controller.
After WIFI controller gets the message that online terminal is sent, the source MAC of message is authentic and valid and is and end
End is one-to-one, can carry out speed limit to NS message/NA message according to source MAC, and can be by the end more than speed limit threshold values
The MAC information at end is notified to administrator.It can be only to allow to receive present count within a preset time that message, which receives speed limit condition,
The message of amount.For example, it can be only to allow to receive a message in 1 second that message, which receives speed limit condition,.If at one second
A message is received in the time of clock, then the quantity that the message received is allowed within the one second time becomes 0.
I.e. at this time if receiving second message again within the one second time, second message received is not meet
Message receives speed limit condition.
If step 203, first message, which meet the message, receives speed limit condition, judged according to first message
Whether the destinations traffic address is occupied.
It in step 203, can be with if the first message that WIFI controller receives meets message and receives speed limit condition
Judge whether destinations traffic address is occupied according to the first message.
Optionally, judge whether the destinations traffic address is occupied according to first message, comprising:
Judge whether the destinations traffic address is recorded in target list according to first message, wherein the mesh
Entitling list includes the mailing address currently occupied by other terminals；
If the destinations traffic address is not recorded in the target list, it is determined that the destinations traffic address is not occupied
With, and the destinations traffic address is added in the target list；
If the destinations traffic address has been recorded in the target list, it is determined that the destinations traffic address is occupied
With.
For example, Wireless Fidelity controller can be in a complete online legal terminal list of internal build, i.e. destination name
It is single.The target list includes the mailing address currently occupied by other terminals.Further, which may include often

Wireless Fidelity controller can judge whether destinations traffic address is recorded in target list according to the first message.Such as
Fruit destinations traffic address is not recorded in target list, then can determine that destinations traffic address is unoccupied, and can be by mesh
Mark mailing address is added in target list.Further, the MAC Address of the terminal of the first message will can be sent, speed limit is advised
Lattice and the time for sending the first message are added in target list.
If destinations traffic address has been recorded in target list, it can determine that destinations traffic address is occupied.I.e.
The terminal for sending the first message prepares the destinations traffic address used by DAD detection and some online terminal is occupied logical
Letter address clashes.
Optionally, it is described the destinations traffic address is added to the step in the target list after, the side
Method further include:
Judge whether the ageing time of target list item corresponding with the destinations traffic address target list Nei expires；
Unicast media access if the ageing time of the target list item expires, to the terminal for sending first message
It controls address and sends third message；
The 4th message that the terminal of first message is returned according to the third message is sent if receiving, is updated
The ageing time of the target list item；
Otherwise, the destinations traffic address being recorded in the target list is removed.
WIFI controller can establish aging mechanism for destination name list.When terminal access network, the message of transmission can refresh
The ageing time of list item in target list.When terminal is for a long time without sending message, then this terminal is in target list
The ageing time of list item cannot will refresh for a long time.When the ageing time of list item differ by more than with the current time in system it is pre-
If when threshold value, the ageing time for being considered as the list item of this terminal expires.
After destinations traffic address is added in target list, WIFI controller may determine that in target list and mesh
Whether the ageing time of the corresponding target list item of mark mailing address expires.
It, can be to the unicast mac address hair for the terminal for sending the first message if the ageing time of target list item expires
Third message is sent, i.e. WIFI controller actively can return to unicast message to the terminal for sending the first message.If WIFI is controlled
Device, which receives, sends the 4th message that the terminal of the first message is returned according to third message, then can update the old of target list item
Change the time, it can from the new time-count cycle for initially entering target list item at the time of receiving four messages.If WIFI is controlled
Device processed, which is not received by, sends the message that the terminal of the first message is returned, then can remove the target being recorded in target list
Mailing address.It should be noted that if WIFI controller, which is not received by, sends the message that the terminal of the first message is returned,
Illustrate that the owner for sending the terminal of the first message at this time may be there is no using terminal.Therefore, can by destinations traffic address from
It is removed in target list, carries out resource release, make other terminals that the destinations traffic address can be used.
If step 204, first message do not meet the message and receive speed limit condition, saves and send first report
The media access control address of the terminal of text.
It in step 204, can if the first message that WIFI controller receives does not meet message and receives speed limit condition
To save the MAC Address for the terminal for sending the first message.This can be had sent and not meet message receives speed limit condition first
The MAC information of the terminal of message notifies the message for making administrator know which terminal is sent to administrator not meet message and connect

Transmitted message when time expires, the target list include the mailing address currently occupied by other terminals；
According to the third message, Xiang Suoshu Wireless Fidelity controller sends the 4th message, so that the Wireless Fidelity control
Device processed updates the ageing time of the target list item according to the 4th message.
It should be noted that WIFI controller can establish aging mechanism for destination name list.When terminal access network, send
Message can refresh the ageing time of the list item in target list.When terminal is for a long time without sending message, then this terminal
The ageing time of list item in target list cannot will refresh for a long time.When the ageing time of list item and system are current
Between when differing by more than preset threshold, the ageing time for being considered as the list item of this terminal expires.It is added by destinations traffic address
After in target list, WIFI controller may determine that the old of the interior target list item corresponding with destinations traffic address of target list
Change whether the time expires.It, can be to the unicast MAC for the terminal for sending the first message if the ageing time of target list item expires
Address sends third message, i.e. WIFI controller actively can return to unicast message to the terminal for sending the first message.
The third message that Wireless Fidelity controller is sent can be received by the unicast media accessing to control address of terminal,
In, third message is after destinations traffic address is added to target list by Wireless Fidelity controller, and Wireless Fidelity controller is sentenced
Transmitted message when the ageing time of target list item corresponding with destinations traffic address expires in disconnected target list out.Destination name
Single mailing address comprising currently having been occupied by other terminals.Next, terminal can be according to third message, to Wireless Fidelity control
Device processed sends the 4th message, so that Wireless Fidelity controller updates the ageing time of target list item according to the 4th message.
If WIFI controller, which receives, sends the 4th message that the terminal of the first message is returned according to third message,
The ageing time of target list item can be updated, it can from initially entering the new of target list item at the time of receiving four messages
Time-count cycle.If WIFI controller, which is not received by, sends the message that the terminal of the first message is returned, note can be removed
It records in the destinations traffic address in target list.It should be noted that if WIFI controller is not received by the first report of transmission
The message that the terminal of text is returned illustrates that the owner for sending the terminal of the first message at this time may be there is no using terminal.Therefore,
Destinations traffic address can be removed out of target list, carry out resource release, make other terminals that the destinations traffic can be used
