Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is carried out Clearly and completely describe, it is clear that described embodiment is only some embodiments of the present application, and It is not all, of embodiment.Based on the embodiment in the application, those of ordinary skill in the art are not doing Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of the application protection.
Before introducing the embodiment of the present application, first introduce data transmission system, to facilitate art technology Personnel are easier to understand the application scenarios of the embodiment of the present application.As it is shown in figure 1, described data transmission system Including: transmitting terminal 100, the transferring equipment collection 200 being connected with transmitting terminal 100, with transferring equipment collection 200 The receiving terminal 300 being connected；Transferring equipment is concentrated and is comprised at least two transferring equipment, specifically can use transfer Equipment 1, transferring equipment 2 ... transferring equipment N represents, N is the natural number more than 1.
Communication linkage between each transferring equipment and transmitting terminal 100 and receiving terminal 300, is all equivalent to one Data transmission channel.Concentrate due to transferring equipment provided herein and at least there are two transferring equipment, So, the application at least has between transmitting terminal 100 and receiving terminal 300 two data transmission channels.
The communication linkage communicated with receiving terminal 300 when transmitting terminal 100 goes wrong, it is impossible to continue dimension After holding the data transmission between transmitting terminal 100 and receiving terminal 300, it is also possible to continue to use other communication chain Connect as the data transmission channel between transmitting terminal 100 and receiving terminal 300, maintain transmitting terminal 100 with this And the data transmission between receiving terminal 300.
When transmitting terminal 100 carries out data transmission with receiving terminal 300, transmitting terminal 100 can be verified and receive Whether there is data transmission channel between end 300, it is assumed that nothing between transmitting terminal 100 and receiving terminal 300 In the case of data transmission channel, transmitting terminal 100 can be concentrated in transferring equipment and determine that one is in normal State transferring equipment, as target transferring equipment.It is then possible to set up transmitting terminal 100 by receiving terminal 300, Communication linkage between target transferring equipment and receiving terminal 300 three.Hereafter, transmitting terminal 100 just can profit Carry out data transmission with receiving terminal 300 by target transferring equipment.
Based on above-mentioned data transmission system, as in figure 2 it is shown, this application provides a kind of data transmission method Embodiment one, the present embodiment is applied to the transmitting terminal of data transmission system.Described method specifically include with Lower step S201～S205:
Step S201: the transmission in response to data message instructs, it is judged that whether target transferring equipment is just in Often state.Wherein, described target transferring equipment is and sends the transfer that the transferring equipment being connected is concentrated Equipment；Described transferring equipment is concentrated and is included at least two transferring equipment.If target transferring equipment is in normally State, then enter step S205；If target transferring equipment is in abnormality, then enter step S202.
In the case of the built vertical communication linkage of transmitting terminal, target transferring equipment and receiving terminal three, represent There is between transmitting terminal and receiving terminal a data transmission channel.Transmitting terminal can use data with existing to pass Defeated passage, sends data message to receiving terminal.
During transmitting terminal utilizes target transferring equipment and receiving terminal to carry out data transmission, due to multiple Reason, may cause target transferring equipment cannot carry out data transmission with transmitting terminal.Such as, owing to sending Holding may be doped with attacking data in the data message that receiving terminal sends, when carrying the number attacking data When it is believed that breath transmission to target transferring equipment, attack data and target transferring equipment can be caused expendable Injury, this may cause cannot proper communication between target transferring equipment and transmitting terminal.Or, transmitting terminal And the physical link between target transferring equipment goes wrong, cause between transmitting terminal and target transferring equipment Cannot proper communication.Or, the hardware device of target transferring equipment itself breaks down, and causes target Transferring equipment cannot normally use, and then cause cannot proper communication between transmitting terminal and target transferring equipment.
Owing to target transferring equipment may occur cannot carrying out data transmission problem with transmitting terminal at any time, so, Utilizing target transferring equipment before receiving terminal sends data message at transmitting terminal, can verify in target Turn the most whether equipment is in normal condition.If target transferring equipment is in normal condition, then it represents that target Transferring equipment can be with transmitting terminal proper communication, if target transferring equipment is in abnormality, then it represents that mesh Mark transferring equipment cannot be with transmitting terminal proper communication.
Wherein, verify whether target transferring equipment is in the process of normal condition and can be: transmitting terminal is to mesh Mark transferring equipment sends the instruction keeping communication linkage.Can be just between target transferring equipment and transmitting terminal During normal open letter, target transferring equipment can send a feedback signal to transmitting terminal.If transmitting terminal receives Feedback signal, then it represents that target transferring equipment is in normal condition, and, target transferring equipment and transmitting terminal Between can keep communication linkage.Between target transferring equipment and transmitting terminal cannot proper communication time, Target transferring equipment cannot send feedback signal to transmitting terminal.If transmitting terminal cannot receive at the appointed time The feedback signal sent to target transferring equipment, then it represents that target transferring equipment is in abnormality, and, Communication linkage cannot be kept between target transferring equipment and transmitting terminal.
As shown in the above, when transmitting terminal between the data message that receiving terminal sends doped with attack number According to time, in the case of being not provided with transferring equipment between transmitting terminal and receiving terminal, receiving terminal is directly as attacking Hit the target of attack of data, in fact it could happen that receiving terminal is hacked data and hits and paralyse, and then cause receiving The problem that end cannot provide service.
Transferring equipment it is provided with in this application, transmitting terminal the attack number sent between transmitting terminal and receiving terminal According to arriving first at transferring equipment, can direct aggression transferring equipment rather than direct aggression so attacking data Receiving terminal.Receiving terminal is avoided directly to be hacked data institute so the transferring equipment that the application provides can have The advantage attacked.
Step S202: after described transferring equipment is concentrated and determined auxiliary transferring equipment, by described data message It is sent to described auxiliary transferring equipment.
After target transferring equipment is in abnormality, then it represents that nothing between target transferring equipment and transmitting terminal Method keeps communication linkage；This data transmission channel i.e. has broken down and cannot be continuing with.In order to maintain Data transmission between transmitting terminal and receiving terminal, now, transmitting terminal can be concentrated the most true in transferring equipment A fixed transferring equipment being in normal condition, the instead auxiliary transferring equipment of target transferring equipment. In subsequent process, transmitting terminal can utilize and carry out data transmission between auxiliary transferring equipment and receiving terminal.
This step determines the process of the transferring equipment of a normal condition, Ke Yiwei:
Transmitting terminal concentrates all transferring equipment (at this point it is possible to not comprising target transferring equipment) to transferring equipment Send request communication instruction.For a transferring equipment, if transferring equipment is in normal condition, then Send a feedback signal to transmitting terminal, if transferring equipment is in abnormality, then will not send out to transmitting terminal Send feedback signal.Therefore, if transmitting terminal can receive the feedback signal that transferring equipment sends, then it represents that This transferring equipment is in normal condition；If transmitting terminal at the appointed time, does not receives transferring equipment and sends Feedback signal, then it represents that this transferring equipment is in abnormality.
Additionally, transmitting terminal can also record each transferring equipment sends the time of feedback signal, if in one Turn equipment and send the time of feedback signal the most early, then it represents that this transferring equipment response speed is the fastest, Jin Erbiao Showing and load less in this transferring equipment, the resource of transferring equipment is the most sufficient.Otherwise, if a transfer sets Preparation send time of feedback signal the most late, then it represents that this transferring equipment response speed is the slowest, and then represent should Loading more in transferring equipment, the resource of transferring equipment is the most nervous.
It is understood that the transferring equipment that response speed the is the fastest (transfer that i.e. Internet resources are more sufficient Equipment), the data message that transmitting terminal sends can be processed faster.The transferring equipment that response speed is the slowest (transferring equipment that i.e. Internet resources are more nervous), it is impossible to process the data letter that transmitting terminal sends faster Breath.
In theory, transmitting terminal can select in one or more transferring equipment being in normal condition at random Select a transferring equipment as auxiliary transferring equipment.But, randomly choosing auxiliary transferring equipment possibly cannot Process the data message of current transmitting terminal faster, in order to comparatively fast process the data message of transmitting terminal, send out Sending end can be using the fastest transferring equipment of Response to selection as auxiliary transferring equipment.
The fastest transferring equipment of transmitting terminal Response to selection as auxiliary transferring equipment, do so Advantage is, quickly can process the data message of transmitting terminal, thus obtain receiving terminal faster Response.Additionally, the speed of transferring equipment response speed and himself load are inversely proportional to, Response to selection Fastest transferring equipment, sets up communication linkage with transmitting terminal；I.e. select transferring equipment pond loads Few transferring equipment and transmitting terminal are set up communication linkage rather than select and are loaded more in transferring equipment pond Transferring equipment sets up communication linkage.So that each transferring equipment all bears the task of carry load.Institute With, this step can be implemented in the purpose of equally loaded in transferring equipment pond.
Certainly, the transferring equipment that Response to selection is fastest in multiple transferring equipment is as in auxiliary Turn equipment, be the implementation of a kind of optimum.It is understood that transmitting terminal can be with Response to selection speed The transferring equipment stood out, as auxiliary transferring equipment.So can also realize load balancing Purpose.
More than for this step determines the process of auxiliary transferring equipment, it is described below being in abnormality The processing procedure of target transferring equipment.For being in abnormality target transferring equipment, can send Warning message, to point out technical staff self to break down, it is impossible to carry out proper communication with transmitting terminal.Skill Target transferring equipment, after checking the source of failure and solving fault, is resetted by art personnel, and again by target Transferring equipment is positioned over transferring equipment and concentrates, and uses when setting up communication linkage for follow-up and other transmitting terminals.
Transmitting terminal is after determining auxiliary transferring equipment, and sets up communication chain determining with auxiliary transferring equipment In the case of connecing, just can send data message to auxiliary transferring equipment.And utilized by auxiliary transferring equipment Data message determines object transmission link, and according to target data message is sent to receiving terminal by transmission link.
Step S203: receive the response message that described auxiliary transferring equipment sends；Wherein, described response letter Breath generates according to described data message for described receiving terminal, and according to target transmission link sends to described auxiliary Help the information of transferring equipment；Described object transmission link is that described auxiliary transferring equipment resolves described data letter Data transmission link determined by after breath.
Receiving terminal, after receiving data message, can generate response message according to data message.Then, will Response message according to target transmission link sends to assisting transferring equipment, and response is believed by auxiliary transferring equipment Breath sends to transmitting terminal, and transmitting terminal just can receive the response message that server sends.
Step S204: send data message to described target transferring equipment.
Turn equipment in the target when being not in abnormality, be then continuing with original communication link, to mesh Mark transferring equipment sends data message, and is sent to receiving terminal by target transferring equipment.
Step S205: receive the response message that described target transferring equipment sends.
Receiving terminal, after receiving data message, can generate response message according to data message.Then, will Response message sends to target transferring equipment, and is sent response message to transmitting terminal by target transferring equipment, Transmitting terminal just can receive the response message that server sends.
Process shown in Fig. 2 is a data transmission procedure between transmitting terminal and receiving terminal, it is possible to understand that It is, when transmitting terminal and receiving terminal proceed data transmission, the process shown in Fig. 2 to be repeated.
In the data transmission system that the present embodiment one is applied, transmitting terminal can be client, transferring equipment Integrating can be as gateway pond, and receiving terminal can be server.Gateway pond comprises at least two gateway, and one The corresponding gateway of transferring equipment.Under this application scenarios, embodiment one can realize client and service Data transmission between device.
The manner can realize the data transmission between client and server, however it is necessary that existing visitor Family end improves, so that client is applicable to the embodiment one that the application provides.Owing to needs are to client End is reconstructed, and therefore the manner is unfavorable for the enforcement of the present embodiment.
It is thus provided that another way, the data transmission system that the present embodiment one is applied in the manner In, transmitting terminal can be client gateways, and transferring equipment integrates can be as gateway pond, and receiving terminal can be service Device.Gateway pond comprises at least two gateway, and a corresponding gateway of transferring equipment.In this application Under scene, embodiment one can realize the data transmission between client gateways and server.
In order to realize the data transmission between client and server, in the embodiment of notebook data transmission method In one, transmitting terminal (client gateways), before sending instruction in response to data, can receive described visitor The data message that family end sends；And after receiving the response message that described auxiliary transferring equipment sends, will Described response message sends to described client, thus realizes the data transmission between client and server.
The improvement of related to client in the manner, all implements, for client in client gateways For, it is not necessary to change original execution process, such that it is able to accomplish client in the case of immovable, Implement the application, and then promote the enforcement of the application.
Fig. 2 show the embodiment one of the data transmission method that transmitting terminal performs, and auxiliary transfer is described below The embodiment of the data transmission method that equipment performs.As it is shown on figure 3, the data transmission provided for the application Embodiment of the method two, specifically includes step S301～304:
Step S301: resolve data message, determines and data message is sent the object transmission chain to receiving terminal Road.Wherein, described data message is, transmitting terminal instructs in response to the transmission of data message, is judging The target transferring equipment being connected with described transmitting terminal is in abnormality, and determines auxiliary in transferring equipment concentration After helping transferring equipment, send to described auxiliary transferring equipment；Described target transferring equipment is and transmitting terminal The transferring equipment that the transferring equipment being connected is concentrated；Wherein, described transferring equipment is concentrated and is included at least two Individual transferring equipment.
At the step S203 transmitting terminal shown in Fig. 2 after ancillary gateway sends data message, assist transfer Equipment then can receive data message.Data message has two kinds of forms: the first form, data packets Include the address date of described transmitting terminal, target data and the address date of described receiving terminal；The second shape Formula, data message includes the address date of described transmitting terminal, target data, the number of addresses of described receiving terminal According to the address date with described target transferring equipment.The difference of two kinds of forms is in the second way also to wrap Address date containing target transferring equipment.
The multi-form of data message, in that case it can be decided that auxiliary transferring equipment sends data message to receiving terminal Implementation.With the first form of data message corresponding the first transmission link is described below, and, The second form corresponding the second transmission link with data message.
The first transmission link: auxiliary transferring equipment-receiving terminal.
In the first form of data message, do not comprise the address information of target transferring equipment, represent and send End is intended to directly be sent data message to receiving terminal by auxiliary transferring equipment.
The second transmission link: auxiliary transferring equipment-target transferring equipment-receiving terminal.
In the second form of data message, comprise the address information of target transferring equipment, represent transmitting terminal Wish to send to target transferring equipment data message, then sent to receiving terminal by target transferring equipment.
Auxiliary transferring equipment, after receiving data message, resolves data message thus obtains data message Data content, thus check the address date whether comprising target transferring equipment in data message.
If data content comprises the address date of target transferring equipment, then it represents that data message is the first Form, then should be sent data message to receiving by the first transmission link corresponding with the first form End, so determining that the first transmission link is object transmission link.
If data message comprises the address date of target transferring equipment, then it represents that data message is the second Form, then should be sent data message to receiving by the second transmission link corresponding with the second form End, so determining that the second transmission link is object transmission link.
Step S302: in the case of determining and all setting up communication linkage with described transmitting terminal and receiving terminal, press Described data message is sent to described receiving terminal by described object transmission link.
