When business data packet that transmitting terminal sends arrives the device of transmission data, the device of transmission data can the first path finding algorithm be that the business datum of the device arriving transmission data is responsible for assigning transmission path.First path finding algorithm can be the path finding algorithm of acquiescence, also can be random from the path finding algorithm list preset that contain multiple path finding algorithm acquisition.For business datum be responsible for assigning transmission path can be specifically adopt hash algorithm of the prior art, certainly can also be other mode, the order such as transmitting the device of data according to arrival is business data packet label, for the first passage transmission subpath that the label business datum that is odd number is responsible for assigning in the first transmission path, for the second channel transmission subpath that the label business datum that is even numbers is responsible for assigning in the first transmission path, can also be distribute according to the congruent numbers of label, specifically can set according to actual needs, not repeat them here.
When the device of transmission data is, after business data packet distributes transmission path, just send business data packet according to distributed transmission path to receiving terminal.It is pointed out that the business data packet of same business carries out transmitting according to different transmission subpaths, namely the present embodiment is when transmitting data, have employed ECMP technology.
Timer can be integrated in the device of transmission data, also can arrange separately.Timer is used for timing.
It is pointed out that when the multiple business data packet belonging to different business reach the device of transmission data simultaneously, which business data packet can be distinguished based on hash algorithm and belong to same business.Every bar transmission subpath comprises at least one transmission node, and transmission node is specifically as follows computer or server.
Step 102, when timer arrives Preset Time, change path finding algorithm, be that the business datum of device arriving transmission data is responsible for assigning the second transmission path according to the path finding algorithm after changing, and by the second transmission path packet, the second transmission path comprises according to tactic at least two the transmission subpaths of second order.
Preset Time can be arranged according to actual needs, such as 1 minute, 5 minutes or 10 minutes.When arriving Preset Time, the device of transmission data just changes path finding algorithm, such as, become the second path finding algorithm, and is that business datum is responsible for assigning the second transmission path according to this second path finding algorithm.Equally, two transmission subpaths are at least also comprised in the second transmission path.Such as, when adopt single even numbers be as above business datum be responsible for assigning transmission subpath time, second path finding algorithm can be allow the business data packet being designated odd number be transmitted by second channel transmission subpath, and the business data packet being designated even numbers is transmitted by first passage transmission subpath.
Preferably, the number of included in each transmission paths transmission subpath is 3 ~ 5.
It is pointed out that the transmission subpath that comprises in the first transmission path can be identical or different with the transmission subpath that comprises in the second transmission path, when the transmission subpath comprised is identical, each putting in order of subpath of transmission is different.

Embodiment two
The present embodiment provides a kind of method transmitting data based on embodiment one.
As shown in Figure 2, be the schematic flow sheet of the method for the transmission data according to the present embodiment.
Step 201, when business data packet arrives the device of transmission data, obtains the first path finding algorithm from the list of rules preset.
The list of rules preset comprises multiple path finding algorithm, and these path finding algorithms all show how to transmit business data packet, is in particular in as business datum is responsible for assigning transmission path.
Step 202, is that the every N number of business datum of device arriving transmission data is responsible for assigning the first transmission path according to following first path finding algorithm, and passes through the distributed each business data packet of the first transmission path, start timer simultaneously:
For the 1st transmission subpath that 0th ~ n in N number of business data packet allocation of packets label is 1;
For the 2nd transmission subpath that (n+1)th ~ 2n in N number of business data packet allocation of packets label is 2;
By that analogy,
The L+1 being L+1 for the Ln+1 in N number of business data packet ~ N number of allocation of packets label transmits subpath;
Wherein, N be greater than 0 integer, L is integer, the first transmission path comprise L+1 transmission subpath.
Wherein, the label of first order sequentially for transmission subpath is ascending.
Step 203, when timer arrives Preset Time, obtains the path finding algorithm different from the first path finding algorithm, such as the second path finding algorithm from the list of rules preset.
Step 204, is that the every N number of business datum of device arriving transmission data is responsible for assigning the second transmission path according to following second path finding algorithm, and passes through the distributed each business data packet of the second transmission path, restart timer simultaneously:
For the 2nd transmission subpath that 0th ~ n in N number of business data packet allocation of packets label is 2;
For the 3rd transmission subpath that (n+1)th ~ 2n in N number of business data packet allocation of packets label is 3;
By that analogy,
The L+1 being L+1 for (L-1) n+1 ~ Ln the allocation of packets label in N number of business data packet transmits subpath;
For the 1st transmission subpath that the Ln+1 in N number of business data packet ~ N number of allocation of packets label is 1;
Wherein, N be greater than 0 integer, L is integer, second transmission path comprises L+1 transmission subpath, second order order for except label be 1 the first transmission subpath except transmission subpath arrange according to the order that label is ascending, and the first transmission subpath that label is 1 is positioned at label is that the L+1 of L+1 transmits after subpath.
Next, when timer arrives Preset Time again, the path finding algorithm that a path finding algorithm different from the second path finding algorithm is different is selected again from the list of rules preset, and to be responsible for assigning transmission path for the business datum of device arriving transmission data, service data transmission bag, until business data packet transmitted complete till.
Can imagine, the Preset Time that timer is arranged at every turn can be identical or different.In the present embodiment, first transmission path is identical with the transmission subpath included by the second transmission path, but put in order difference, the first order order that the transmission subpath comprised in first transmission path is corresponding is: the 1st transmission subpath, the 2nd transmission subpath, L-2 transmits subpath, L+1 transmits subpath, the second order order that the transmission subpath comprised in second transmission path is corresponding is: the 2nd transmission subpath, the 3rd transmission subpath,, L+1 transmits subpath, the 1st transmission subpath.
According to the method for the transmission data of the present embodiment, the path finding algorithm adopted is, the order of device arriving transmission data according to business data packet is that business datum is responsible for assigning transmission path, simple in rule, transmission is convenient, and by transform path selective rule, make malicious persons cannot acquisition approach selective rule thus the content of business datum cannot be obtained, ensure the fail safe of business datum.
Embodiment three
The method of the present embodiment to the transmission data of embodiment one and embodiment two does further supplementary notes.
Because the status transmission of network can along with time variations, and transmission subpath change too much or frequently the decline that transmission path can cause the transmission quality of business data packet, whether the transfer instruction that therefore can detect business data packet in the following manner reaches default QoS(Quality of Services, service quality) requirement, adjust the number of time and/or the transmission subpath changing transmission path:
When receiving the transmission quality representing business data packet and arriving the first testing result of the qos requirement preset, reduce Preset Time and/or path finding algorithm be replaced by the 3rd path finding algorithm, when timer arrives Preset Time, be that the business datum of device arriving transmission data is responsible for assigning the 3rd transmission path according to the 3rd path finding algorithm, and by the 3rd transmission path business data packet, the number of the transmission subpath included by the 3rd transmission path is greater than the second transmission path;
When the transmission quality receiving expression business data packet does not arrive the second testing result of default qos requirement, increase Preset Time and/or path finding algorithm be replaced by the 4th path finding algorithm, when timer arrives Preset Time, be that the business datum of device arriving transmission data is responsible for assigning the 4th transmission path according to the 4th path finding algorithm, and by the 4th transmission path business data packet, the number of the transmission subpath included by the 4th transmission path is less than the second transmission path.
Before selecting business data packet arrival receiving terminal in the present embodiment, whether the transmission quality being detected business data packet by detection node reaches default qos requirement, certainly can also be directly whether to reach default qos requirement by the transmission quality of receiving terminal detection business data packet.Specifically the business data packet that each arrives detection node can be detected, also can detect every several packet, specifically can set according to actual needs.It is pointed out that increasing Preset Time means the frequency reducing to change path finding algorithm.When the transmission quality of business data packet does not arrive default qos requirement, need to increase Preset Time, make it reach default qos requirement with the transmission quality improving business data packet as far as possible, namely can making the qos requirement that the transmission quality of business data packet reaches default as far as possible, malicious persons can being made cannot to obtain the content of business data packet by changing path finding algorithm again.Equally, when the transmission quality of business data packet reaches default qos requirement, allow to reduce Preset Time to accelerate to change the frequency of path finding algorithm, make malicious persons cannot get the transmission rule of business data packet, even if thus get business data packet and also cannot combine in order business data packet, and then its particular content can not be obtained.
Particularly, default qos requirement can whether be reached by the transmission quality of the time delay of business data packet and packet drop detection business data packet.If reach qos requirement, then detection node generates the device that the first testing result is sent to transmission data, the device of such transmission data can when transmitting the business data packet of this business again, suitable reduction Preset Time, namely reduce the time changing transmission path, or increase the number of transmission subpath; If do not reach qos requirement, then detection node abandons the business data packet not reaching qos requirement, and generate the device that the second testing result is sent to transmission data, like this, the device of transmission data can when transmitting the business data packet of this business again, and namely suitable increase Preset Time increases the time changing transmission path, or reduce the number of transmission subpath, to ensure that the business data packet transmitted can reach qos requirement as far as possible.OAM bag can detect that some business data packet is dropped, notice transmitting terminal resends, or carries out detecting by upper strata (such as, ICP/IP protocol layer) notice transmitting terminal of laying equal stress on and resend the business data packet of loss, specifically can set according to actual needs, not repeat them here.After the device of transmission data have adjusted the quantity of transmission subpath at adjustment Preset Time or by adjustment path finding algorithm, in the process of following service data transmission bag again, the transmission subpath comprised in the transmission path that the Preset Time after adjusting and/or selection all can be selected to distribute is not more than the path finding algorithm of the quantity of the transmission subpath after adjustment.
It is to be noted, the time that path finding algorithm is changed in adjustment specifically can adjust timer, the number of adjustment transmission subpath can be specifically change path finding algorithm, is chosen as the path finding algorithm that transmission subpath that business datum is responsible for assigning is less from the list of rules preset.The operation of adjustment Preset Time and path finding algorithm can occur simultaneously, also can only adjust Preset Time or path finding algorithm, specifically can set according to actual needs.
By the method for the transmission data of the present embodiment, the number transmitting subpath in the transmission path of business data packet can be adjusted dynamically, the time changing path finding algorithm can also be adjusted dynamically, so both can ensure the fail safe of business datum, the transmission quality of business can be ensured again.

According to the 3rd path finding algorithm, 61st ~ 70 business data packet arriving the device 302 of these transmission data are transmitted by the 4th transmission subpath, 71st ~ 80 business data packet arriving the device 302 of these transmission data are transmitted by the 3rd transmission subpath, 81st ~ 90 business data packet arriving the device 302 of these transmission data are transmitted, until the 90th business data packet end of transmission by the 2nd transmission subpath.
Suppose, the device 302 of transmission data is when transferring the 50th business data packet, receive the transmission quality of business data packet that detection node 304 sends when not reaching the second testing result of qos requirement, can select to increase the Preset Time of timer 303, such as, be adjusted to and transfer 50 business data packet and just reach Preset Time.So 51st ~ 90 business data packet are all transmitted according to the second path finding algorithm.
Alternatively, detection node 304 can detect the transmission quality of the business data packet arriving detection node 304, and feeds back to the device 302 of transmission data, to make device 302 accommodation Preset Time and/or the path finding algorithm of transmission data.
