In the present embodiment, the MESH network includes that multiple AP, these AP are located between AC and terminal device, according to
The location of AP is different, the AP in MESH network can be specifically divided into transmitting terminal AP and (refer to that sending equipment with message is connected
AP), receiving terminal AP (referring to the AP being connected with message receiving device) and between transmitting terminal AP and receiving terminal AP turn
Hair AP.
When AP determines that the data message for receiving carries label forwarding information, can further it is determined that the data message
Label forwarding information in the purpose forwarding label that includes for the label of this AP when, it is believed that the AP is transmitting terminal AP or forwarding
AP, therefore the corresponding purpose of the purpose forwarding label can be searched in the corresponding relation of the forwarding label with AP of local record
AP, and by the data message forwarding to the purpose AP；When it is determined that the purpose forwarding label is the label of this AP, can be with
The AP is thought for receiving terminal AP, and the AP is needed the data message forwarding to terminal device, therefore can remove the datagram
The label forwarding information of text, the target MAC (Media Access Control) address according to the data message is searched MAC Address list item and is forwarded.
Whether step 103, the outgoing interface for determining whether the data message are MESHLINK mouthfuls；If it is, turning step

To make the objects, technical solutions and advantages of the present invention become more apparent, with reference to Fig. 2 to the solution of the present invention
It is described in further detail.
Refer to Fig. 2, be MESH network schematic diagram in the embodiment of the present invention, the MESH network include AC, AP1, AP2,
AP3 and terminal A and terminal B, it is assumed that wherein terminal A will be sent datagram by the MESH network to terminal B, then terminal
A is that message sends equipment, and terminal B is message receiving device.
In the present embodiment, AC can distribute to the fixed forwarding labels of the AP mono-, for example when some AP reaches the standard grade
The forwarding label of AP1 is label 1, and the forwarding label of AP2 is label 2, and the forwarding label of AP3 is label 3, and the forwarding label is used for
Carried when message is forwarded in MESH network.When some data message is forwarded in MESH network for the first time, according to the present invention
The message forwarding method of offer, AP when data message is received process step as shown in figure 3, including step：
Step 301, AP1 judge whether the data message carries label forwarding information, if it is not, then going to step 302；
Specifically, AP1 is when the data message of terminal A transmissions is received, it can be determined that whether the data message carries mark
Sign forwarding information.Because the data message from terminal A when terminal B is sent to, the first AP of process is AP1, therefore the data
Message is also not added with label forwarding information, therefore AP1 can determine that the data message does not carry label forwarding information, so that also true
AP1 is determined for transmitting terminal AP.
Step 302, AP1 judge whether the outgoing interface of the data message is MESHLINK mouthfuls, if then going to step 303；If
It is no, then go to step 310；
Because AP1 determines that the data message does not carry label forwarding information, it is therefore desirable to further determine that the data message
Outgoing interface whether be MESHLINK mouthfuls.AP1 can be looked into according to the target MAC (Media Access Control) address of message in local MAC Address list item
The corresponding outgoing interface of the target MAC (Media Access Control) address is looked for, then judges whether the outgoing interface is MESHLINK mouthfuls.
Step 303, AP1 are that the data message adds label forwarding information and is forwarded to AP2；
When it is MESHLINK mouthfuls that AP1 determines the outgoing interface of the data message, it is believed that the message can be in MEAH
Forwarded in network.Yet with not carrying label forwarding information in the data message, therefore AP1 needs to be that the data message is added
Label forwarding information.Used as one embodiment, the specific method for adding label forwarding information is：AP1 is by the corresponding forwardings of this AP1
Label (label 1) as the data message source forwarding label；Target MAC (Media Access Control) address according to the message is in local MAC Address
Purpose AP, the i.e. AP3 corresponding to target MAC (Media Access Control) address are searched in list item, it is then corresponding with AP3 in the forwarding label of local record
Purpose forwarding label of the corresponding forwarding labels (label 3) of the purpose AP3 as the message is searched in relation；Therefore AP1 can
Think the message addition label forwarding information, the label forwarding information includes the source forwarding label (label 1) and institute
State purpose forwarding label (label 3).Afterwards can will add label forwarding information after data message forwarding to next-hop AP (i.e.
AP2)。
Step 304, AP2 judge whether the data message carries label forwarding information, if so, then going to step 305；
AP2 is when the data message of AP1 transmissions is received, it can be determined that whether the data message carries label forwarding information.
Due to the data message on AP1 added label forwarding information, therefore AP2 can determine that the data message carries label
Forwarding information.
Step 305, AP2 judge whether the purpose forwarding label included in the label forwarding information is this AP；If it is not, then
Go to step 306；
Through judging, the purpose forwarding label included in the label forwarding information of the data message is label 3, is not AP2
Corresponding forwarding label, thus may determine that the AP2 is forwarding AP.
Step 306, AP2 are according to purpose forwarding label by the data message forwarding to AP3；
Because the purpose forwarding label included in the label forwarding information of the data message is not the corresponding forwarding marks of AP2
Sign, therefore AP2 can to search the purpose forwarding label corresponding in the corresponding relation of the forwarding label with AP of local record
Purpose AP (i.e. AP3), and by the data message forwarding to the purpose AP.
Step 307, AP3 judge whether the data message carries label forwarding information, if so, then going to step 308；
AP3 is when the data message of AP2 transmissions is received, it can be determined that whether the data message carries label forwarding information.
Due to the data message on AP1 added label forwarding information, therefore AP3 can determine that the data message carries label
Forwarding information.
Step 308, AP3 judge whether the purpose forwarding label included in the label forwarding information is this AP；If so, then
Go to step 309；
Through judging, the purpose forwarding label included in the label forwarding information of the data message is label 3, exactly AP3
Corresponding forwarding label, thus may determine that the AP3 is receiving terminal AP.
Step 309, AP3 remove the label forwarding information of the data message, by the data message forwarding to terminal B；
When it is determined that the purpose forwarding label included in the label forwarding information is AP3, AP3 can remove the data
The label forwarding information of message, the target MAC (Media Access Control) address according to the message is searched MAC Address list item and is forwarded the packet to terminal B.
Step 310, according to MAC Address list item forward.
If the outgoing interface of the data message is non-MESHLINK mouthfuls, can determine that the data message cannot be in MESH
Forwarded in network, therefore AP1 can forward the message according to MAC Address list item.
As can be seen here, the present invention need to can only be looked into 3 MESH networks jumped in receiving terminal AP and transmitting terminal AP
MAC address entries are looked for, MESH messages are forwarded by forwarding label in AP is forwarded, instructed such that it is able to reduce to be searched by MAC address entries
