(2) record the concrete data volume of every kind of current transmission of data;
(3) reference weight index separately carries out convergent-divergent to every kind of data volume;
(4), be every kind of data allocations bandwidth according to the data volume behind the convergent-divergent.
Above-mentioned dynamic allocation method, wherein, default priority is to set according to the significance level of every kind of data and user's visit possibility in the step (1).
Above-mentioned dynamic allocation method, wherein, in the step (3), the data volume behind the convergent-divergent is the current concrete data volume that records and the product of weight index.
Above-mentioned dynamic allocation method, wherein, step (4) also comprises the reference allocation proportion that is obtained every kind of data by the data volume behind the convergent-divergent, gives every kind of data allocations bandwidth according to described with reference to allocation proportion again.
Above-mentioned dynamic allocation method, wherein, the reference allocation proportion of data and this data allocations to bandwidth be directly proportional.
The present invention contrasts prior art following beneficial effect: the present invention's foundation current concrete data volume that every kind of data had, the different weight of reference is amplified these data volumes or is dwindled again, obtain the reference allocation proportion of every kind of data, again by specifically distributing bandwidth with reference to allocation proportion.Bandwidth allocation methods of the present invention can be adjusted the bandwidth of distribution after making data volume take place significantly to change in real time, thereby under any circumstance can both the reasonable distribution bandwidth.
Description of drawings
Fig. 1 is the flow chart of dynamic allocation method preferred embodiment of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 shows the flow process of Bandwidth Dynamic Allocation method embodiment of the present invention.See also Fig. 1, below in conjunction with the idiographic flow of a case description Bandwidth Dynamic Allocation method.In this example, total bandwidth is 40M, and A, B, C, D, five kinds of data of E are arranged, the data volume of A, B, C class data size substantially constant wherein, and D, E class data are along with the variation of time has bigger variation.And be provided with 4 priority: high, high, general, low.Suppose that the category-A data priority is high, the category-B data priority is higher, and C class data priority is low, and D class data priority is general, and E class data priority is low.Here, priority is to set according to the significance level of every kind of data and user's visit possibility.
Step S1: the priority default according to every kind of data is respectively weight index of every kind of data setting.In this example, can priority be that high weight index is set to 3, priority is that high weight index is set to 2, and priority is that general weight index is set to 1, and priority is that low weight index is set to 0.5.
Step S2: the concrete data volume that records every kind of current transmission of data.In this example, morning 9 each data that records data volume be: the A data volume is that 1M, B data volume are that 2M, C data volume are that 3M, D data volume are that 1M, E data volume are 5M.Afternoon, the data volume of 3 each data that records was: the A data volume is that 1M, B data volume are that 2M, C data volume are that 3M, D data volume are that 5M, E data volume are 10M.
Step S3: the weight index with reference to current, carry out convergent-divergent to every kind of data volume.In this example, be as scaled results with the product that records data volume and weight index.So for 9 data volumes that record in morning, the data volume that recomputates every kind of data according to weight is as shown in the table:
| A | B | C | D | E |
| 1*3＝3 | 2*2＝4 | 3*0.5＝1.5 | 1*1＝1 | 5*0.5＝2.5 |
According to the data total amount behind the weight convergent-divergent is 3+4+1.5+1+2.5=12.
For 3 data volumes that record in afternoon, the data volume that recomputates every kind of data according to weight is as shown in the table:
| A | B | C | D | E |
| 1*3＝3 | 2*2＝4 | 3*0.5＝1.5 | 5*1＝5 | 10*0.5＝5 |
According to weight change data total amount later is 3+4+1.5+5+5=18.5.
Step S4: according to the data volume behind the convergent-divergent is every kind of data allocations bandwidth.Obtaining earlier the reference allocation proportion of every kind of data according to the data volume behind the convergent-divergent, is every kind of data allocations bandwidth according to the reference allocation proportion again, and the reference allocation proportion of data and this data allocations to bandwidth be directly proportional.In this example, with ratio shared in the total data amount of the data volume behind every kind of data convergent-divergent behind convergent-divergent as the reference allocation proportion, again the dedicated bandwidth total amount multiply by this with reference to allocation proportion as every kind of bandwidth that data are deserved.
For 9 data volume in morning, the result who redistributes after the bandwidth is as shown in the table:
| A | B | C | D | E |
| 3/12*40 | 4/12*40 | 1.5/12*40 | 1/12*40 | 2.5/12*40 |
| 10 | 13.3 | 5 | 3.3 | 8.3 |
It can be seen from the table, the bandwidth of last A data allocations is 10M, and the bandwidth of B data allocations is 13.3M, and the bandwidth of C data allocations is 5M, and the bandwidth of D data allocations is 3.3M, and the bandwidth of E data allocations is 8.3M.
For 3 data volume in afternoon, the result who redistributes after the bandwidth is as shown in the table:
| A | B | C | D | E |
| 3/18.5*40 | 4/18.5*40 | 1.5/18.5*40 | 5/18.5*40 | 5/18.5*40 |
| 6.4 | 8.6 | 3.2 | 10.8 | 10.8 |
It can be seen from the table, the bandwidth of last A data allocations is 6.4M, and the bandwidth of B data allocations is 8.6M, and the bandwidth of C data allocations is 3.2M, and the bandwidth of D data allocations is 10.8M, and the bandwidth of E data allocations is 10.8M.
