Fig. 2 is referred to, Fig. 2 is a kind of schematic flow sheet of data transmission method disclosed in the embodiment of the present invention.The data
Transmission method may comprise steps of.
Step S201, log equipment receive peer-to-peer network UP2P packets, and the UP2P packets include destination address.
Step S202, judge whether the UP2P packets have networked and set described in being destined to according to the destination address
It is standby, if so, then performing step S203；Conversely, then the log equipment processes the UP2P packets.
Step S203, judge whether the UP2P packets are broadcast data packet, if so, then to the log equipment
Nearby device forwards the UP2P packets；Conversely, then performing step S204.
Step S204, judge in the addressing list of log equipment with the presence or absence of the destination address, if so, then to institute
State the corresponding purpose equipment of destination address and forward the UP2P packets；Conversely, then to the nearby device of the log equipment
Forward the UP2P packets.
The log equipment can include entered the Mesh node device, than Node1 as shown in Figure 1~
Any node equipment of Node7.
The UP2P packets can include destination address (can refer to destination slogan again), judge that the destination address is
It is no whether identical with the address of the log equipment, if identical, judge that the UP2P packets are sent to described networking
Equipment；Conversely, then judging that the UP2P packets are not destined to the log equipment.When judging that the UP2P packets are
When being sent to the log equipment, the log equipment to the UP2P packets can carry out data analysis or be uploaded to
The treatment operation such as described monitor supervision platform.
The nearby device of the log equipment can refer to the log equipment one jump or multi-hop in the range of node set
It is standby.Such as, if as shown in figure 1, the log equipment is Node4, it is stipulated that the node device in the range of the jumps of the Node4 mono- is made
It is the nearby device of the Node4, then the nearby device can be Node1, Node2, Node6 and Node7；If it is described entered
Net equipment is Node4, it is stipulated that node device in the range of the Node4 double bounces as the Node4 nearby device, then it is described
Nearby device can be Node3 and Node5.
The addressing list of the log equipment can include the address of the device node being connected with the log equipment.Than
Such as, if as shown in figure 1, the log equipment be Node4, the device node being connected with the Node4 be Node1, Node2,
Node6 and Node7, then can store the address of Node1, Node2, Node6 and Node7 in the addressing list of the Node4.
Further, the UP2P packet structure schematic diagrames shown in Fig. 3 are referred to, the UP2P packets can also include
Digit-marker, source address, bag sequence number, packet length and variable data, wherein, the UP2P packets are by the first domain to the 7th domain
Totally 7 domains constitute, and first domain includes 4 digit-markers of byte；
Second domain and the 3rd domain respectively account for 4 bytes, comprising the destination address；
4th domain and the 5th domain respectively account for 4 bytes, comprising the source address；
6th domain includes 2 bag sequence numbers of byte；
7th domain includes the variable data.
It should be noted that the judgement operation of step S202, step S203 and step S204 can also network described
Performed in other equipment outside equipment, such as server etc..
As a kind of optional implementation method, treat that log equipment can be by following steps 11)~step 13) it is scanned into
Net：
Step 11), the log equipment to treat log equipment send particular arrangement frame, the particular arrangement frame include spy

The service set identifier SSID of Mesh where the log equipment and the variable data of encryption.
Step 12), it is described treat log equipment receive log equipment send particular arrangement frame.
Step 13), described treat log equipment when judging that the Mesh is described treating according to the Mesh identification numbers of the SSID
During log equipment network to be accessed, then the network level of the log equipment is obtained from the SSID, and to network
The minimum log equipment of level sends networking solicited message.
It should be noted that in the embodiment of the present invention, the log equipment of the Mesh can have dividing for network level, most
Low level can be the equipment for accessing AP, and its network level can be 0, and the network level of the next stage equipment of the equipment can
Think 1, the network level of the equipment of next stage again of the next stage equipment can be 2, the like.
The network level maximum of equipment can be 255, be 255 to set in network level to realize unlimited equipment circulation
After standby, the network level of the equipment that next stage is accessed can reset to 0, circulate successively.
For example, referring to a kind of schematic diagram for treating log equipment scanning networking shown in Fig. 4, Node1~Node7 can
As the log equipment of the Mesh, if the Node5 and Node7 for treating log equipment Node8 scannings, wherein Node5
Network level be 0, the network level of the Node7 can be 255, then the Node8 can select the Node7 to be connect
Enter.
It should be noted that in the embodiment of the present invention, " 0 network level " is that the next stage of " 255 network level " is formed,
So " 0 network level " may be considered " 256 network level ", the like, " 1 network level " may be considered " 257 networks
Level " etc..
Implement the embodiment of the present invention, isolating for the Mesh can be prevented.
Optionally, the specific purposes address can refer to 0 or other for the destination address character；It is described special
Source address can refer to 0 or other for the source address character；The special AP addresses can refer to 0 or other be not described
Character of AP addresses etc..
Wherein, the form of the particular arrangement frame can be with as shown in figure 5, the particular arrangement frame includes the specific purposes
The byte of address 6,6 bytes of the special source address, 2 bytes of the bag sequence number, 0X80 and variable data, wherein described can
Becoming data includes the SSID and encrypted message of root router of the Mesh, and the variable data inserts the spy after can encrypting
Sent in different configuration frame.
In the method described by Fig. 1, when, log equipment judges that the UP2P packets are not destined to network set
It is standby, and to there is the destination address in broadcast data packet, and the addressing list of the log equipment in the UP2P packets
When, then forward the UP2P packets to the corresponding purpose equipment of the destination address；Or, when the log equipment judges
