VLAN (Virtual Local Area Network, virtual LAN) is a kind of equipment by LAN from patrolling
It collects upper rather than is physically divided into multiple network segments, to realize the emerging data switching technology of virtual workgroup.Due to it
It is logically to divide, rather than physically divide, so each work station in the same VLAN is not limited to together
In one physical extent, i.e., these work stations can be in different physics LAN (Local Area Network, LAN) nets
Section.Broadcast and unicast traffic inside one VLAN will not be all forwarded in other VLAN, to help to control flow, reduce
Equipment investment, the safety for simplifying network management, improving network.
Currently, the standard for dividing VLAN has very much, such as：It divides VLAN according to port, divided according to MAC Address
VLAN, VLAN is divided according to network layer and is divided according to IP (Internet Protocol, the agreement interconnected between network) multicast
VLAN etc..A kind of division sides VLAN based on VAP (Virtual Access Point, virtual access point) of traditional bridge connected
Method is：VLAN is divided according to port, this method is by binding the same ports VLAN agreements ID, when there is user data
When packet is by port, port is that user data package adds a VLAN agreement ID, and material is thus formed what is identified with VLAN ID
Multiple virtual ports.
It is actively to use in port when there is another side ports of the data packet Jing Guo wireless access point based on same reason
User data packet adds the mark of a SSID (Service Set Identifier, service set), so that it may with by the port
It is divided into the multiple virtual ports identified with SSID.
After the operation of port virtualization more than access point apparatus completion, the embodiment of the present invention is by providing a kind of report
Literary retransmission method completes effective forwarding to message, and shown in Figure 1, specifically implementation method includes：
Step S101, after receiving the first message comprising first identifier, according to pair of first identifier and second identifier
It should be related to, determine the corresponding second identifier of first identifier in first message.
Step S102 determines the first virtual port and the second virtual terminal according to the first identifier and the second identifier
Mouthful.
Step S103, the second message that will be converted to by first message protocol pass through first virtual port
It is forwarded with second virtual port.
Before executing step S101, the one-to-one relationship of first identifier and second identifier is preset, such as set
SSID1 corresponds to VLAN ID1, and SSID2 corresponds to VLAN ID2, and so on.In this way, carrying the first of first identifier when receiving
After message, it can determine that the first identifier in the message is corresponding according to the first identifier information of the first message received
Second identifier.
Wherein it should be noted that if the first identifier is service set SSID, then the second identifier is virtual
LAN ID VLAN ID；If the first identifier is VLAN ID, the second identifier is SSID.

When client selects one of connection from the SSID name of acquisition, carrying selection will be sent out to wireless access point device
SSID name connection request message, after wireless access point device receives the message, can on uplink by the message into
Row data conversion, 802.11 frame data through the first message are converted to 802.3 frame data, and the second message after converting no longer is taken
Mark with SSID name.In order to identify the message in the wireless access point device of subsequent cascaded, need artificially
First message is specifically converted into the second message of 802.3 formats by addition mark after message conversion, and by institute
The corresponding second identifier of the first identifier for including is stated in the first message to be placed in second message；Or by described first
Message is converted into the second message of 802.3 formats, and the first identifier for including in first message is placed in described
In two messages.
For example, client selects connection SSID1, wireless access point device to receive connection request from the SSID name of acquisition
Message, and message conversion is carried out, transformed message no longer also has SSID1 marks, is needed at this time according to SSID name and VLAN
The correspondence addition mark of interface, the mark of addition can be different SSID name, such as SSID1, SSID2 etc., certainly
The mark of addition can also be corresponding with SSID name VLAN interface title, such as VLAN ID1, VLAN ID2 etc., also
It is to say that addition mark can be first identifier, can also be second identifier.
In addition, the first virtual port and the second virtual port that are related to for following content of the embodiment of the present invention are made in advance
Setting, that is, it is the side received after the SSID mark completions carried according to message are distributed that it is corresponding, which to set the first virtual port, the
Corresponding two virtual ports are another side ports being connect with optical interface or Ethernet protocol interface, are divided generally by VLAN
The multiple virtual ports obtained afterwards.
In step s 102, the first virtual port and the second virtual port are determined by first identifier and second identifier
Implementation method is as follows：
If the first identifier is SSID, first message and second message are uplink message；According to described
One mark and the second identifier, determine the first virtual port and the second virtual port, including：It is determined according to the first identifier
First virtual port, and the second virtual port is determined according to the second identifier；
If the first identifier is VLAN ID, first message and second message are uplink message；According to described
First identifier and the second identifier determine the first virtual port and the second virtual port, including：
The first virtual port is determined according to the second identifier, and the second virtual terminal is determined according to the first identifier
Mouthful.
If the first identifier is SSID, first message and second message are downlink message；According to described
One mark and the second identifier, determine the first virtual port and the second virtual port, including：It is determined according to the first identifier
First virtual port, and the second virtual port is determined according to the second identifier；
If the first identifier is VLAN ID, first message and second message are downlink message；According to described
First identifier and the second identifier determine the first virtual port and the second virtual port, including：
The first virtual port is determined according to the second identifier, and the second virtual terminal is determined according to the first identifier
