Detailed content is referring to described in S609.
Referring to shown in Fig. 4, the one embodiment for the method that multipath shunts in the embodiment of the present invention includes:
101, routing device obtains target flow ratio, flow of the target flow than the channel for two or more
Than；
In the framework for carrying out multi-path transmission, since the bandwidth of the transmission path in different paths may not be identical, institute
With it is desirable to carry out shunting transmission when carrying out data transmission, i.e. more data are distributed in the biggish channel of the bandwidth of path band
Flow, less data flow is distributed in the lesser channel of the bandwidth in path, in this way, realizing in a manner of by accurately shunting quickly
Transmission.So in embodiments of the present invention, routing device first obtains a desired target flow ratio, the target flow ratio is
It is intended that it is described two or more channel flow ratio, for example, two passes if it exists, and it is intended that institute
Stating the ratio between the flow that two passes transmit respectively is 7:3, then the target flow ratio is 7:3.The target flow ratio
It can be and be artificially arranged.
102, the routing device is respectively directed to according to the target flow score with the logic port of respective number described
Physical port corresponding to two or more channel；
Physical port is for connecting the interface between physical equipment, and logic port is the end for being used for Differentiated Services in logic
Mouthful.So each physical port corresponds to the channel of a paths, logic port is used when carrying out data transmission when having determined
Number when, then routing device is respectively directed to the physics than the logic port to distribute respective number according to the target flow
Port.For example, and 10 logic ports have been determined to carry out data transmission, then by 7 logical ends if target flow ratio is 7:3
Mouth is directed toward a physical port, other 3 logic ports are directed toward another physical port.It should be noted that logic port
Quantity be rate control granularity according to actual needs to set and design, granularity requirements more detailed rules and regulations quantity is bigger, this hair
It is illustrated for 10 for ease of understanding in bright embodiment, the quantity of logic port is generally far larger than 10 in actual use
It is a.
103, the routing device passes through preset algorithm to the logic port packet distribution；
After the mapping relations of logic port and physical port have been determined, then to the logic port packet distribution,
In this way, flow-rate ratio when data traffic being made to reach physical port is close to desired target flow ratio.
104, the routing device obtains the actual flow ratio that statistic unit counts the physical port；
Since the length of each data packet may not be identical, so working as the routing device for each data packet average mark
When being dealt into the logic port, actually carry out be between the physical port data packet number according to the shunting of target flow ratio
Transmission, and and be according to accurate data traffic than progress shunting transmit.For example, if target flow ratio is 7:3, and 7 are patrolled
It collects port and is directed toward a physical port, 3 logic ports are directed toward another physical port, and since the length of each data packet can
Can not be identical, then the data traffic ratio that two physical ports are an actually-received may be 6:4 after carrying out data packet transmission.Institute
To carry out traffic statistics to the physical port by statistic unit, obtain reality after the physical port receives data packet
Border flow-rate ratio, and the actual flow ratio is fed back into the routing device, so that the routing device is to the physics end
Mouth mapped logical port number is adjusted, to reach desired target flow ratio.
Optionally, it if since every transmission primaries data packet just carries out an actual flow statistics, and feeds back and is adjusted, this
Sample can greatly increase the expense of system, so, statistic unit can be obtained according to predetermined period and the physical port is counted
Actual flow ratio, the predetermined period, which can be, to be artificially arranged, be also possible to according to the time for calculating data transmission and about
Surely it is calculated.In this way, being both able to achieve accurate shunting, the expense of system is decreased.
105, the routing device is according to the actual flow than adjusting the physical port mapped logic port
Quantity, so that the difference of the ratio of the ratio of actual flow ratio and target flow ratio is less than preset threshold；
When the routing device actual flow ratio that gets of judgement and desired target flow ratio, which exist, to be entered and left, i.e. institute
The difference for stating the ratio of actual flow ratio and the ratio of target flow ratio is greater than preset threshold, then needs by adjusting the object
The quantity of port mapped logic port is managed, so that actual flow ratio is close to target flow ratio.For example, if desired mesh
Marking flow-rate ratio is 7:3, and the actual flow ratio got is 6:4, then it represents that the wherein stream of the channel actual transmissions of a paths
Amount is fewer than desired flow, and the desired flow of flow-rate ratio of another channel actual transmissions is more, so need to be adjusted,
Such as, if being that 7 logic ports are directed toward the first physical port before, 3 logic ports are directed toward the second physical port, then can be by institute
State a transfer in 3 logic ports of the second physical port mapped and be directed toward first physical port, after transfer then at
It is directed toward the first physical port for 8 logic ports, 2 logic ports are directed toward the second physical port.In this way, by adjusting the object
After managing port mapped logical port number, then makes actual flow ratio closer to desired target flow ratio, realize
It is accurate to shunt transmission.
In the embodiment of the present invention, a desired target flow ratio is obtained first, is matched according to desired target flow score
The logic port of respective number is respectively directed to physical port corresponding to two or more the channel, by imputing in advance
Logic port packet distribution described in normal direction, in this way, data packet then can target flow ratio desirably be distributed to logic port
Corresponding physical port, but since the length of each data packet is not identical, so even if relatively fifty-fifty by data packet
It is distributed to each logic port, and the practical flow-rate ratio distributed and desired target flow ratio can have discrepancy, so also needing
The actual flow ratio that statistic unit counts the physical port is obtained again, after getting actual flow ratio, then to the object
Reason port mapped logical port number is increased and decreased to adjust the flow of the physical port actual transmissions, so that the reality
The difference of the ratio of the ratio of border flow-rate ratio and target flow ratio is less than preset threshold and is mentioned with realizing that multipath accurately shunts
High data transmission in network efficiency.

Non- most reasonable flow-rate ratio, it is possible to estimation first is measured in real time to the actual bandwidth situation of outlet openings, estimated
As a result, subtracting currently practical occupied bandwidth number according to estimation result, the bandwidth ability of the outlet openings is obtained, further according to described logical
The actual bandwidth capabilities might in road carries out the dynamic setting of target flow ratio.
202, target flow ratio, the target flow ratio is arranged according to the actual bandwidth capabilities might in the routing device

After the bandwidth in road is detected, detect that the bandwidth of first passage is 3M, and the occupied bandwidth of presently described first passage is
2M, i.e., the bandwidth ability of the described first passage are 1M；The bandwidth of second channel is 2M, and presently described second channel is occupied
Bandwidth is also 1M, then the bandwidth ability of the second channel is 1M, then can be according to actual bandwidth ability to first passage and the
The target flow ratio 1:1 that two channel settling periods are hoped.During carrying out data transmission, by the band for detecting two passes
When variation has occurred in width, for example the bandwidth ability variation of the first passage is 2M, and the bandwidth ability of the second channel is still
1M, then can modify desired target flow ratio to first passage and second channel according to testing result is 2:1.
