Embodiment two
Present embodiment provides a kind of method of the transmission of data based on embodiment one.
As shown in Figure 2, be the schematic flow sheet according to the method for the transmission of data of present embodiment.
Comprise a plurality of path finding algorithms in the default list of rules, these path finding algorithms all show how business data packet is transmitted, and are in particular in to be the business datum transmission path that is responsible for assigning.
For the 0th ~ n data in N the business data packet be responsible for assigning label be 1 the 1st the transmission subpath;
For the n+1 in N the business data packet ~ 2n data be responsible for assigning label be 2 the 2nd the transmission subpath;
By that analogy,
For the Ln+1 in N the business data packet ~ N data label that is responsible for assigning is the L+1 transmission subpath of L+1;
Wherein, N is the integer greater than 0, and L is integer, comprises L+1 transmission subpath in the first transmission path.
Wherein, first order is sequentially ascending for the label of transmission subpath.
Step 203 when timer arrives Preset Time, is obtained the path finding algorithm different from the first path finding algorithm, for example the second path finding algorithm from default list of rules.
For the 0th ~ n data in N the business data packet be responsible for assigning label be 2 the 2nd the transmission subpath;
For the n+1 in N the business data packet ~ 2n data be responsible for assigning label be 3 the 3rd the transmission subpath;
By that analogy,
For the label that is responsible for assigning of (L-1) n+1 ~ Ln the data in N the business data packet is the L+1 transmission subpath of L+1;
For the Ln+1 in N the business data packet ~ N data be responsible for assigning label be 1 the 1st the transmission subpath;
Wherein, N is the integer greater than 0, L is integer, comprise L+1 transmission subpath in the second transmission path, second order is sequentially for being that 1 the transmission subpath of the first transmission the subpath arranged according to the ascending order of label except label, and label is that the first transmission subpath of 1 is positioned at after the L+1 transmission subpath that label is L+1.
Next, when timer arrives Preset Time again, from default list of rules, select again a path finding algorithm different path finding algorithm different from the second path finding algorithm, and be the business datum of the device that the arrives the transmission of data transmission path that is responsible for assigning, the service data transmission bag, until business data packet be transmitted complete till.
What can imagine is that the each Preset Time that arranges of timer can be identical or different.In the present embodiment, the included transmission subpath of the first transmission path and the second transmission path is identical, but put in order difference, the first order that the transmission subpath that comprises in the first transmission path is corresponding sequentially is: the 1st transmission subpath, the 2nd transmission subpath, L-2 transmission subpath, L+1 transmit subpath, the second order that the transmission subpath that comprises in the second transmission path is corresponding sequentially is: the 2nd transmission subpath, the 3rd transmission subpath,, L+1 transmission subpath, the 1st transmission subpath.
Method according to the transmission of data of present embodiment, the path finding algorithm that adopts is, the order that arrives the device of the transmission of data according to business data packet is the business datum transmission path that is responsible for assigning, simple in rule, transmission is convenient, and by the transform path selective rule, thereby so that malicious persons can't the acquisition approach selective rule can't be obtained the content of business datum, guarantee the fail safe of business datum.
Embodiment three
Present embodiment is done further supplementary notes to the method for the transmission of data of embodiment one and embodiment two.
Because the status transmission of network can change along with the time, and the transmission subpath too much or frequently change the decline that transmission path can cause the transmission quality of business data packet, whether the transfer instruction that therefore can detect in the following manner business data packet reaches default QoS(Quality of Services, service quality) requirement, adjust the time of changing transmission path and/or the number of transmitting subpath:
When the transmission quality that receives the expression business data packet arrives the first testing result of default qos requirement, reduce Preset Time and/or path finding algorithm be replaced by Third Road directly to select rule, when timer arrives Preset Time, directly select rule to be the business datum of the device that arrives the transmission of data the 3rd transmission path that is responsible for assigning according to Third Road, and by the 3rd transmission path business data packet, the number of the transmission subpath that the 3rd transmission path is included is greater than the second transmission path;
When the transmission quality that receives the expression business data packet does not arrive the second testing result of default qos requirement, increase Preset Time and/or path finding algorithm is replaced by the 4th path finding algorithm, when timer arrives Preset Time, be the business datum of the device that arrives the transmission of data the 4th transmission path that is responsible for assigning according to the 4th path finding algorithm, and by the 4th transmission path business data packet, the number of the transmission subpath that the 4th transmission path is included is less than the second transmission path.
Select business data packet to arrive before the receiving terminal in the present embodiment, whether the transmission quality that is detected business data packet by detection node reaches default qos requirement, can also be whether direct transmission quality by receiving terminal detection business data packet reaches default qos requirement certainly.Specifically can detect each business data packet that arrives detection node, also can detect every several packets, specifically can set according to actual needs.It is pointed out that increasing Preset Time means the frequency that reduces 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 that improves business data packet as far as possible, namely can make the transmission quality of business data packet reach default qos requirement as far as possible, again can be by changing path finding algorithm so that malicious persons can't be obtained the content of business data packet.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, so that malicious persons can't get access to the transmission rule of business data packet, even also can't make up in order business data packet thereby get access to business data packet, and then can not obtain its particular content.
Whether the transmission quality that particularly, can detect business data packet by time-delay and the packet drop of business data packet reaches default qos requirement.If reach qos requirement, then detection node generates the device that the first testing result is sent to the transmission of data, the device of the transmission of data can be when transmitting this professional business data packet again like this, the suitable Preset Time that reduces, namely reduce to change the time of transmission path, perhaps increase the number of transmission subpath; If do not reach qos requirement, then detection node abandons the business data packet that does not reach qos requirement, and generate the device that the second testing result is sent to the transmission of data, like this, the device of the transmission of data can be when transmitting this professional business data packet again, and suitable increase Preset Time namely increases the time of changing transmission path, perhaps reduce to transmit the number of subpath, can reach qos requirement to guarantee the business data packet of being transmitted as far as possible.The OAM bag can detect some business data packet and be dropped, the notice transmitting terminal resends, and perhaps detects the notice transmitting terminal of laying equal stress on by upper strata (for example, ICP/IP protocol layer) and resends the business data packet of losing, specifically can set according to actual needs, not repeat them here.The device of the transmission of data is after adjusting Preset Time or having adjusted the quantity of transmission subpath by adjusting path finding algorithm, next in the process of service data transmission bag, the transmission subpath that comprises in the transmission path that the Preset Time after all can selecting to adjust and/or selection distribute is not more than the path finding algorithm of the quantity of the transmission subpath after the adjustment again.
It is to be noted, adjust the time of changing path finding algorithm and specifically can adjust timer, the number of adjusting the transmission subpath specifically can be to change path finding algorithm, is chosen as the less path finding algorithm of transmission subpath that business datum is responsible for assigning from default list of rules.The operation of adjusting 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.
The method of the transmission of data by present embodiment, can adjust dynamically the number of transmission subpath in the transmission path of business data packet, can also adjust dynamically the time of changing path finding algorithm, so both can guarantee the fail safe of business datum, can guarantee again professional transmission quality.
