Step 304, trunking using the configuration information (configuration information carried i.e. in probe messages) carry out two kinds or The link configuration of two or more link mediums.

In one example, for " link that two or more link medium is carried out using the configuration information is matched somebody with somebody Put " process, can include but is not limited to：Determine the corresponding AES of the safety code using the detection code；Using the encryption Algorithm is decrypted treatment to the safety code, the configuration information after being decrypted；Two are carried out using the configuration information after the decryption The link configuration of kind or two or more link mediums.

In one example, for " routing device enters line number according to the corresponding weight of every kind of link medium and trunking According to transmission " process, can include but is not limited to：Routing device determines every kind of link medium according to the weight of every kind of link medium The flow-rate ratio shared, and the flow-rate ratio shared according to every kind of link medium sends data to trunking；Or, according to every kind of chain The weight of road medium determines the priority of every kind of link medium, and priority according to every kind of link medium and data is preferential Level sends data to trunking；Or, the maximum link medium of weight is defined as primary link medium, by other link mediums It is defined as reserve link medium, when the primary link medium does not break down, by the primary link medium to trunking Data are sent, when the primary link medium breaks down, reserve link medium is switched to and is sent data to trunking.

In one example, if trunking is in Preset Time, the detection of at least two routing devices transmission is received Message (has at least two routing devices to send probe messages to trunking), then trunking can also be according to preset strategy A routing device for needing relaying is chosen from least two routing devices, for the routing device of selection, trunking profit The link configuration of two or more link medium is carried out with configuration information.Wherein, preset strategy can include but not limit In：The reception of the priority and/or probe messages of the link medium between routing device and trunking is sequentially.For example, it is assumed that , better than the priority of power line medium, the priority of power line medium is better than WLAN for the priority of wired ethernet medium The priority of medium, if trunking receives the probe messages that routing device 1 sends by wired ethernet medium, by nothing Line LAN Medium receives the probe messages of the transmission of routing device 2, then choose routing device 1 for the route for needing relaying sets It is standby.If trunking first receive routing device 1 transmission probe messages, after receive routing device 2 transmission probe messages, Routing device 1 is chosen to need the routing device of relaying.If trunking receives routing device 1 by wired ethernet medium The probe messages of transmission, the probe messages that routing device 2 sends are received by wired ethernet medium, are first received route and are set Standby 1 probe messages for sending, after receive the probe messages of the transmission of routing device 2, choose routing device 1 to need the road of relaying By equipment.

Based on above-mentioned technical proposal, in the embodiment of the present application, between routing device and trunking can by two kinds or Two or more link mediums carry out data transmission, and so, when the laser propagation effect of certain link medium is bad, can also pass through Other link mediums carry out data transmission, so as to reduce the situation of data packetloss, it is ensured that the q＆r of trunking, and User experience is improved, expansion uplink bandwidth is reached, is realized QoS (Quality of Service, service quality) points The purpose such as class and backup of uplink.

Below in conjunction with the application scenarios shown in Fig. 4, above-mentioned technical proposal is illustrated.Trunking and routing device it Between there is power line medium, Wireless LAN Medium, wired ethernet medium, coaxial cable medium.In actual applications, not Power line medium, Wireless LAN Medium, wired ethernet medium, coaxial cable medium are confined to, are situated between with power line in Fig. 2 Illustrated as a example by matter, Wireless LAN Medium, wired ethernet medium.Power line medium is the data communication based on power line Medium, can use HomePlug (Home Plug PowerLine Alliance, Home Plug alliance) agreement, based on electric power The trunking scheme of line medium is referred to as PLC (Power Line Communication, power line communication) relayings.Coaxial cable medium It is the data communication medium that Ethernet protocol is used based on wired TV coaxial cable net, HomePlug agreements, base can be used It is referred to as coaxial cable relaying in the trunking scheme of coaxial cable medium.Wireless LAN Medium is based on ISM (Industrial Scientific Medical, industrial scientific medical) channel (such as 2.4G, 5G) data communication medium, can use IEEE802.11 (Institute of Electrical and Electronics Engineers, Electrical and Electronic engineer Association) agreement, the trunking scheme based on Wireless LAN Medium is referred to as wireless relay.Wired ethernet medium is based on coaxial The data communication medium of cable, twisted-pair feeder and optical fiber, can use IEEE802.3 agreements, the relaying side based on wired ethernet medium Formula is referred to as line relay.

Under above-mentioned application scenarios, the data transmission method that the embodiment of the present application is proposed may comprise steps of：

Step 1, user complete the configuration of WLAN in routing device, such as configuration SSID of WLAN and close The information such as code, wireless parameter (such as HT patterns, channel requirements), repeat no more to this process.

Step 2, routing device are all link mediums generation probe messages that this equipment is supported, such as power line medium is given birth to It is Wireless LAN Medium generation probe messages 2 into probe messages 1, and for wired ethernet medium generates probe messages 3.Its In, the type of the corresponding probe messages of different link mediums can be with difference, it is also possible to identical, for example, being power line medium generation Probe messages 1 can be DHCP message, the probe messages 2 for being Wireless LAN Medium generation can be for Beacon messages The probe messages 3 of wired ethernet medium generation can be DHCP message.To the type of this probe messages in the embodiment of the present application It is not limited.

Step 3, routing device periodically send probe messages by every kind of link medium to trunking.

Step 4, trunking receive the probe messages that routing device is sent by every kind of link medium.

For example, routing device periodically can send probe messages 1 by power line medium to trunking, so that in Probe messages 1 are received by power line medium after equipment.And, routing device can periodically pass through Wireless LAN Medium Probe messages 2 are sent to trunking, so that trunking receives probe messages 2 by Wireless LAN Medium.And, route Equipment periodically can send probe messages 3 by wired ethernet medium to trunking, so that trunking is by having Line ethernet medium receives probe messages 3.

Wherein, routing device send probe messages cycle can be configured according to practical experience, every time reach send During the cycle, probe messages are just sent by every kind of link medium.In one example, if the period ratio of probe messages is shorter, Then the transmission frequency of probe messages is higher, may take compared with multiple resource, and if the cycle of probe messages is long, then detection is reported The transmission frequency of text is relatively low, and trunking may be caused to timely receive probe messages.Wherein in an implementation method, The cycle of probe messages is set to 60 seconds.

In one example, routing device can add configuration information when probe messages are generated in probe messages, should Configuration information can be included but is not limited to：The MAC Address and IP address of routing device, the SSID of WLAN and password, nothing The information such as line parameter (such as HT patterns, channel requirements).

Further, for security consideration, routing device can also be carried out using predetermined encryption algorithm to configuration information Encryption, the configuration information after encryption is added in probe messages.Specifically, routing device can use predetermined encryption algorithm pair Configuration information is encrypted, and the corresponding detection code of predetermined encryption algorithm is added into probe messages, and by encryption after with confidence Breath is defined as safety code, and the safety code is added into probe messages.

Wherein, the detection code can be character string, and different detection codes can correspond to different AESs, for example, Detection code A can correspond to AES 1, and detection code B can correspond to AES 2 etc..Assuming that routing device uses AES 1 Configuration information is encrypted, then detection code A is added to probe messages.

Wherein it is possible to increase Vendor Specific (specific supplier) field in probe messages, and in Vendor Specific fields add detection code and safety code, and the content of detection code is the character string of regular length, and the content of safety code is By the configuration information encrypted.As shown in table 1, it is an example of Vendor Specific fields, Element ID (elements Identify) for the content of 100 expression Value (value) fields is detection code.Element ID are the content of 101 expression Value fields It is safety code, safety code is by the corresponding AESs of detection code A (such as AES (Advanced Encryption Standard, Advanced Encryption Standard) algorithm, DES (Data Encryption Standard, data encryption standards) algorithm etc.) The configuration information being encrypted.

Table 1

Element id fields	Value fields
		100	Detection code A
101	Safety code X

In one example, by the message encapsulation format difference that different link mediums are used, therefore, it is possible to use not Represent that current message is probe messages with mark.For example, power line medium is directed to, can be by the MAC Header of probe messages Type (type) value is set to the first mark (such as 1111) in (head), to represent current message as probe messages, if trunking After power line medium receives message, Type values are 1111 in parsing MAC Header, determine that this message is to visit Observe and predict text.For Wireless LAN Medium, Type values in the MAC Header of probe messages can be set to the second mark (such as 0000) 1111, and by Subtype (subtype) value in MAC Header are set to, to represent current message as probe messages, if After Wireless LAN Medium receives message, Type values are 0000 to trunking in parsing MAC Header, and MAC Subtype values are 1111 in Header, determine that this message is probe messages.For wired ethernet medium, will can visit Type values are set to 1111 in observing and predicting the MAC Header of text, to represent current message as probe messages, if trunking passes through After wired ethernet medium receives message, Type values are 1111 in parsing MAC Header, determine that this message is to visit Observe and predict text.

If step 5, trunking are in Preset Time, the probe messages that a routing device sends are received only, then will The routing device is defined as needing the routing device of relaying；If trunking receives the detection of at least two routing devices transmission Message, then choose a routing device for needing relaying according to preset strategy from least two routing devices.Further, pin Routing device to needing relaying, trunking performs step 6.

Wherein, trunking can wait Preset Time, and based on all probe messages received in Preset Time, choosing Take out the routing device for needing relaying.In one example, if Preset Time is shorter, trunking possibly cannot be associated with Preferable routing device, if Preset Time is more long, may cause the speed of trunking completion network trunk slower.Wherein In one implementation method, Preset Time is set to 60 seconds.

Wherein, preset strategy can be included but is not limited to：Link medium between routing device and trunking it is preferential The reception of level and/or probe messages is sequentially.For example, it is assumed that the priority of wired ethernet medium is preferential better than power line medium Level, the priority of the priority better than Wireless LAN Medium of power line medium, if trunking passes through wired ethernet medium The probe messages of the transmission of routing device 1 are received, the detection report that routing device 2 sends is received by Wireless LAN Medium Text, then choose routing device 1 to need the routing device of relaying.If trunking first receives the detection of the transmission of routing device 1 Message, after receive routing device 2 transmission probe messages, then choose routing device 1 for need relaying routing device.If in The probe messages that routing device 1 sends are received by wired ethernet medium after equipment, is received by wired ethernet medium To the probe messages that routing device 2 sends, first receive the probe messages of the transmission of routing device 1, after receive routing device 2 and send out The probe messages sent, then choose routing device 1 to need the routing device of relaying.

Step 6, trunking parse detection code and safety code from the probe messages for receiving.

Wherein, for above-mentioned probe messages 1, probe messages 2, probe messages 3, the processing procedure of trunking is identical, is Simplified description, subsequently illustrates so that trunking is to a treatment for probe messages as an example.

In one example, trunking can analyze the Vendor of probe messages after probe messages are received Specific fields, and find the corresponding Value fields of Element ID100, the content i.e. detection code of the Value fields (such as detection code A).And, trunking can also find the corresponding Value fields of Element ID101, the Value fields Content is namely by the safety code (such as safety code X) of encryption.

Step 7, trunking determine the corresponding AES of the safety code using the detection code.

Wherein, different detection codes can correspond to different AESs, and, trunking can with preservation ＆ testing code with The corresponding relation of the corresponding relation of AES, such as detection code A and AES 1, detection code B is corresponding with AES 2 to close System.Based on this, for the process of " trunking determines the corresponding AES of the safety code using the detection code ", trunking By inquiring about the corresponding relation of detection code and AES, the corresponding AES of code, the AES are can be detected It is exactly the corresponding AES of safety code.

To the safety code, (what is parsed from probe messages passes through encryption using the AES for step 8, trunking The safety code for the treatment of) treatment is decrypted, the configuration information after being decrypted.

In one example, the configuration information can include MAC Address and IP address, the WLAN of routing device SSID and password, wireless parameter (such as HT patterns, channel requirements) information.

Based on this, trunking can also check the real mac address of MAC Address in safety code and probe messages (i.e. The source MAC of probe messages) it is whether consistent.If consistent, verify successfully, probe messages through safety certification, if not Unanimously, then verification failure, abandons the probe messages.

Step 9, trunking determine the link medium between this trunking and routing device.

In one example, because trunking can be by power line medium, Wireless LAN Medium, wired ethernet Medium, coaxial cable medium receive the probe messages of routing device transmission, therefore, trunking can determine this trunking Link medium between routing device is power line medium, Wireless LAN Medium, wired ethernet medium, coaxial cable are situated between Matter.

Step 10, trunking carry out the link configuration of each link medium using the configuration information after decryption.

Wherein, for every kind of link medium, trunking can carry out link medium using the configuration information after decryption Downlink configuration, the uplink configuration of link medium is carried out using the configuration information after decryption.

For " trunking carries out the uplink configuration of power line medium/coaxial cable medium using configuration information " Process, can include but is not limited to following manner：Port can be set to link layer intercommunication pattern by trunking；Trunking Can using configuration information routing device complete register, from routing device application link identification (i.e. subsequent transmission message when make Link identification)；IP address based on routing device, by DHCP (Dynamic Host Configuration Protocol, DHCP) mode, from routing device application IP address, and by the default route of this trunking It is set to the IP address of routing device.

For the process of " trunking carries out the uplink configuration of wired ethernet medium using configuration information ", can be with Port is set to link layer intercommunication pattern；IP address based on routing device, by DHCP modes from routing device application IP Address, the default route of trunking is set to the IP address of routing device.

For the process of " trunking carries out the uplink configuration of Wireless LAN Medium using configuration information ", relaying Port can be set to link layer intercommunication pattern by equipment；SSID and password based on WLAN, trunking are attempted connecting The wireless network of routing device is connect, and wireless connection is set up with routing device, after wireless connection is successfully established, based on route The IP address of equipment, trunking by DHCP modes from routing device application IP address, and default route can be set to The IP address of routing device.

For " trunking using configuration information carry out power line medium, coaxial cable medium, wired ethernet medium, The process of the downlink configuration of Wireless LAN Medium ", trunking can (such as HT patterns, channel will based on wireless parameter Ask), this trunking is set to Client (client) pattern, and the setting of descending wireless network is carried out, and incited somebody to action described Wireless parameter is stored in configuration file.

Wherein, wireless parameter is suggestion of the routing device to the wireless parameter of trunking.For example, routing device is multifrequency Wireless router, when trunking is multi-frequency radio repeater, routing device advises trunking with 5.1G mode transistroutes When the wireless signal of equipment, i.e. terminal device transfer data to trunking by 2.4G or 5.8G modes, trunking Routing device is transferred data to by 5.1G modes, wireless relay is done using 5.1G frequency ranges equivalent to specified trunking, made Wireless coverage is done with 2.4G and 5.8G frequency ranges.

Step 11, for every kind of link medium, trunking obtain the corresponding link-quality of the link medium and link ginseng Number, and be that the link medium distributes weight according to the link-quality and the link parameter, and it is corresponding according to every kind of link medium Weight carries out data transmission with routing device.Routing device obtains the corresponding link-quality of the link medium and link parameter, and Be that the link medium distributes weight according to the link-quality and the link parameter, and according to the corresponding weight of every kind of link medium with Trunking carries out data transmission.

Wherein, the mistake of the corresponding link-quality (i.e. the quality of up-link) of power line medium is obtained for trunking Journey, trunking can send ICMP by power line medium according to certain hour cycle (such as 1 second) to routing device (Internet Control Message Protocol, Internet Control Message Protocol) request message, and by power line Medium receives the ICMP response messages that routing device is returned.The contents such as packet loss, message delay based on ICMP response messages, in The corresponding link-quality of power line medium can be counted after equipment.For example, when packet loss is got over hour, link-quality is better, when When packet loss is bigger, link-quality is poorer；When message delay is got over hour, link-quality is better, when message delay is bigger, link Quality is poorer.

Similarly, the mistake of Wireless LAN Medium/corresponding link-quality of wired ethernet medium is obtained for trunking Journey, the process of link-quality corresponding with power line medium is obtained is similar to, and difference is：By Wireless LAN Medium/wired Ethernet medium sends ICMP request messages to routing device, and is received by Wireless LAN Medium/wired ethernet medium The ICMP response messages that routing device is returned, repeat no more to this.

Wherein, link parameter can include but is not limited to the parameters, relaying such as connection speed, connection bandwidth, link priority Equipment can be directly obtained the parameters such as connection speed, connection bandwidth, link priority.For example, the connection speed of power line medium Rate A, connection bandwidth A, the connection speed B of Wireless LAN Medium, connection bandwidth B, the connection speed C of wired ethernet medium, Connection bandwidth C.The priority of wired ethernet medium is better than the priority of power line medium, and the priority of power line medium is better than The priority of Wireless LAN Medium.

Wherein, for the process of " trunking is that link medium distributes weight according to link-quality and link parameter ", respectively The corresponding weight of link medium can be a constant, be the factors such as reference link quality and link parameter, based on preset strategy Distribution.During weight is distributed, an example of preset strategy can be：The weight of inaccessible link medium is 0. For reachable link medium, if link-quality is better, the weight being assigned to is bigger, if link-quality is poorer, is assigned to Weight it is smaller；If connection speed is bigger, the weight being assigned to is bigger, if connection speed is smaller, the weight being assigned to is got over It is small；If connection bandwidth is bigger, the weight being assigned to is bigger, if connection bandwidth is smaller, the weight being assigned to is smaller；If link Priority is bigger, then the weight being assigned to is bigger, if link priority is smaller, the weight being assigned to is smaller.

To this preset strategy, can be configured according to practical experience, such as be used above-mentioned strategy, it is without limitation. In subsequent process, for convenience of description, the weight for thinking the distribution of wired ethernet medium is 6, is the weight of power line medium distribution It is 3, the weight for being Wireless LAN Medium distribution is illustrated as a example by 1.

For the process of " trunking carries out data transmission according to the weight of each link medium with routing device ", relaying The routing policy that equipment can be selected according to user, carries out data transmission with routing device in different ways.If for example, route Strategy is balancing link load strategy, and trunking determines the stream that every kind of link medium is shared according to the weight of every kind of link medium Amount ratio, and the flow-rate ratio shared according to every kind of link medium sends data to routing device.If routing policy is business QOS (Quality of Service, service quality) strategy, trunking determines every kind of link according to the weight of every kind of link medium The priority of medium, and priority and the priority of data according to every kind of link medium send data to routing device.If Routing policy is link backup function policy, and the maximum link medium of weight is defined as primary link medium by trunking, by it Its link medium is defined as reserve link medium, when primary link medium does not break down, is sent out by main chain road direction routing device Data are sent, when primary link medium breaks down, reserve link medium is switched to and is sent data.

Situation one, trunking determines the flow-rate ratio that every kind of link medium is shared according to the weight of every kind of link medium, and The flow-rate ratio shared according to every kind of link medium sends data to routing device.For example, it is assumed that the weight of wired ethernet medium It is 6, power line medium weight is 3, the weight of Wireless LAN Medium is 1, then wired ethernet medium, power line medium, nothing The flow-rate ratio that line LAN Medium is shared is 6:3:1, i.e., for 10 data messages, there are 6 data messages can be by wired Ethernet medium sends, and has 3 data messages to be sent by power line medium, has 1 data message can be by wireless LAN Medium sends.

In order to realize above-mentioned functions, wherein in an implementation method：After data message is received, according to data message Fixed field content (such as source MAC, source IP address, purpose IP address, target MAC (Media Access Control) address, message characteristic code) enter Row HASH is calculated, and obtains HASH summaries, and carries out remainder treatment with weight and 10 to HASH summaries, if remainder result is 0-5, The data message is sent by wired ethernet medium, if remainder result is 6-8, the datagram is sent by power line medium Text, if remainder result is 9, the data message is sent by Wireless LAN Medium.

Certainly, aforesaid way is an example, all to realize " for 10 data messages, there is 6 data messages Sent by wired ethernet medium, there are 3 data messages to be sent by power line medium, there is 1 data message to pass through wireless The mode of LAN Medium transmission ", within the application protection domain.

Situation two, trunking determines the priority of every kind of link medium according to the weight of every kind of link medium, and according to The priority of every kind of link medium and the priority of data send data to routing device.

For example, it is assumed that the weight of wired ethernet medium is 6, power line medium weight is 3, the power of Wireless LAN Medium It is again 1, then, better than the priority of power line medium, the priority of power line medium is better than nothing for the priority of wired ethernet medium The priority of line LAN Medium.And, message characteristic code (such as numerical value of certain fixed field), purpose IP ground according to data The fields such as location, can identify type of service, and this RM is not limited, and determine the preferential of data based on type of service Level.Further, the data of high priority can be forwarded by the link medium of high priority, by the number of middle priority Forwarded according to the link medium by middle priority, the data of low priority are turned by the link medium of low priority Hair.

The maximum link medium of weight is defined as primary link medium by situation three, trunking, and other link mediums are true It is set to reserve link medium, when primary link medium does not break down, data is sent by main chain road direction routing device, in main chain When road medium breaks down, it is switched to reserve link medium and sends data.

For example, it is assumed that the weight of wired ethernet medium is 6, power line medium weight is 3, the power of Wireless LAN Medium It is again 1, then wired ethernet medium is defined as primary link medium, power line medium, Wireless LAN Medium is defined as standby Use link medium.When wired ethernet medium does not break down, send all to routing device by wired ethernet medium Data.When wired ethernet medium breaks down, power line medium is switched into primary link medium, and by power line medium All data are sent to routing device.

In one example, when being changed due to network environment, the corresponding link-quality of each link medium can become Change, cause the weight of each link medium distribution to change.For situation one, when the weight of link medium changes, weight Newly determine the flow-rate ratio that every kind of link medium is shared, and the flow-rate ratio shared according to every kind of link medium sends number to routing device According to.For situation two, when the weight of link medium changes, the priority of every kind of link medium is redefined, and The priority of priority and data according to every kind of link medium sends data to routing device.For situation one and feelings Condition two is no longer repeated in detail.

But, for situation three, when the weight of link medium changes, primary link medium may be caused to switch to standby With link medium, reserve link medium switches to primary link medium, and active-standby switch can cause network temporarily to interrupt, and influences user Experience.Based on this, in order to avoid adjusting primary link medium/reserve link medium repeatedly, can be solved with entrance link elastic mechanism The certainly adjustment problem repeatedly of primary link medium/reserve link medium.

For example, it is the first numerical value (such as 3) to set link upper elastic limit, it is the first number to set the initial value of link switching number of times Value 3.Because trunking is periodic statistics link-quality, therefore, in the corresponding link-quality of statistics link medium every time When, if based on current link-quality, causing active-standby switch event (explanation link is unstable), then by link switching number of times Subtract 1；If based on current link-quality, there is no active-standby switch event (explanation link stabilization), if link switching number of times is First numerical value, then keep link switching number of times constant, if link switching number of times is less than the first numerical value, link switching number of times is added 1, by that analogy.

Further, when primary link medium does not break down, if link switching number of times is not 0, being not carried out " will Primary link medium switches to reserve link medium, and reserve link medium is switched into primary link medium ", if link switching number of times It is 0, then can performs and " primary link medium be switched into reserve link medium, switches to primary link to be situated between in reserve link medium Matter ".But, when primary link medium breaks down, then it represents that primary link medium is unreachable, at this point it is possible to by standby chain Road medium switches to primary link medium.

In one example, for the process of " routing device obtains the corresponding link-quality of the link medium ", route sets It is standby to will not be repeated here, or trunking is being obtained by the way of above-mentioned trunking obtains link-quality To after the corresponding link-quality of each link medium, the corresponding link-quality of each link medium is notified to routing device, so that road The corresponding link-quality of each link medium is got by equipment, be will not be repeated here.For " routing device obtains link medium pair The link parameter answered, be that link medium distributes weight according to link-quality and link parameter " process, referring to above-mentioned trunking Treatment, will not be repeated here.For " routing device carries out data transmission according to the weight of each link medium with trunking " Process, referring to the data transmission procedure of above-mentioned trunking, it is no longer repeated herein.

By above-mentioned treatment, trunking can succeed the data of transistroute equipment, and, trunking is in success After after the data of routing device, can be by by LED (Light Emitting Diode, light emitting diode) indicator lamp, being set to Normal bright state, to point out user repeated success.It is of course also possible to pass through other states of LED light, user has been pointed out Repeated success, is not limited to this process.
