In the band width configuration of embodiment one as shown in Figure 3, if the flow of every kind of application in this system has all surpassed configuration, so all can be according to the traffic forwarding message of configuration, be voice and video 50M, HTTP 30M, P2P 20M, the flow of supposing the flow of present voice and video and HTTP is all very large, voice and video is 70M particularly, HTTP is 40M, and the flow that current P2P downloads only has 10M, and total bandwidth also has the 10M bandwidth left so, so in the above embodiment of the present invention, voice and video and HTTP are according to the allocated bandwidth of carrying out of the priority that disposes, if the allocation proportion parameter in the application correspondence of this system's medium priority 1 is 3, the allocation proportion parameter of the application correspondence of priority 2 is 2, and the allocation proportion parameter of the application correspondence of priority 3 is 1, then the ratio of voice and video distribution is 3/(3+2), the ratio that HTTP distributes is 2/(3+2), so the bandwidth that voice and video can distribute is 10M * 3/5=6M, the bandwidth that HTTP distributes is 10M * 2/5=4M.
According to the abovementioned embodiments of the present invention, partition size parameter and allocation proportion parameter are distributed token computation, distribute the step of token parameter to comprise to obtain: to distribute token computation by following formula, distribute token parameter Token_quantum to obtain, formula is: Token_quantum=n*m, wherein, n is the partition size parameter, and m is the allocation proportion parameter.
In the above embodiment of the present invention, according to distributing the token parameter and distributing number of times to carry out bandwidth calculation, can comprise with the step of obtaining bandwidth parameter: carry out bandwidth calculation by following formula, to obtain bandwidth parameter Token_deficit, formula is: Token_deficit=Token_quantum*(j+1), wherein, j is for distributing number of times, and the initial value of j is zero.
Particularly, distribution object for different priorities, can initialization a granularity that distributes bandwidth, and obtain corresponding partition size parameter, then calculate the distribution token parameter of corresponding different priorities by formula Token_quantum=n*m, then the distribution token parameter of different priorities is carried out bandwidth calculation, obtain bandwidth parameter.
For example, exist 0 to 7 to have 8 priority altogether in the supposing the system, corresponding different priority i allocation proportion parameter is: 8-i; It is 64K that initialization distributes the granularity of bandwidth, then corresponding partition size parameter is the token (being ms_64k) of every millisecond of 64K, then the distribution token parameter Token_quantum[i of corresponding different priority i] be: Token_quantum[i]=ms_64k*(8-i).
Then calculate respectively the bandwidth parameter Token_deficit[i of the corresponding different priorities of different distribution number of times j] [j]: Token_deficit[i] [j]=Token_quantum[i] * (j+1), the initial value of j is zero, and distribution number of times j wherein distributes Product-factor.

More specifically, suppose receive distribution object E carried out the request of allocated bandwidth after, and the father node C that monitors distribution object has in the situation of remaining bandwidth, if node F has residue, show as so node C and node A has residue, according to high priority, the principle of low-level priority allocation bandwidth, distribution object E can distribute bandwidth to node C request, the original allocation number of times of distribution object E is set to j=0, increase j, the bandwidth of distribution object E distribution is Token_deficit[0 so] [j], if node C has not had remaining bandwidth, then reduce the value of j, at this time the bandwidth of distribution object E distribution allows the bandwidth of node C just satisfy all the time.Node C in this time dynamic equilibrium between yellow and green, node A dynamic equilibrium between redness and green; If the bandwidth that distribution object E uses is also little, can not all use the remaining bandwidth of node F, show as node A and also have bandwidth left, Node B and node D remaining bandwidth of distribution node A proportionally so, the original allocation number of times j of Node B and node D is set to 0, increase to distribute number of times j, Node B and the node D bandwidth of distributing respectively is Token_deficit[2 so] [j] and Token_deficit[3] [j], at this time A dynamic equilibrium between redness and green.
In addition, use the method for distribution bandwidth of the present invention, in the band width configuration of as shown in Figure 5 embodiment three, the up total amount of user's video must not surpass 300M, in the video bandwidth of 300M, preferentially guarantee the first video, and the bandwidth maximum of the first video can be broken through 100M(and mean the bandwidth that can go to tie up the P2P download, but summation still can not surpass 300M); In the first video, preferentially ensure again the second video, maximum can break through 100M(and mean the bandwidth that can remove to tie up other P2P videos).
Need to prove, can in the computer system such as one group of computer executable instructions, carry out in the step shown in the flow chart of accompanying drawing, and, although there is shown logical order in flow process, but in some cases, can carry out step shown or that describe with the order that is different from herein.
From above description, can find out, the present invention has realized following technique effect: by the present invention, obtain the priority parameters of distribution object, and obtain the allocation proportion parameter corresponding with priority parameters, then according to the partition size parameter of distribution object, allocation proportion parameter and distribution number of times calculate and obtain bandwidth parameter, and utilized bandwidth parametric distribution bandwidth, thereby when distributing untapped bandwidth to solve that various application distribute bandwidth in the prior art according to the different proportion of the application of different priorities, can not be to the application priority allocation bandwidth of high priority, thereby so that E-Packeting, the application of high priority postpones very large problem, realized and to have distributed untapped bandwidth according to the priority of different application, sufficient utilized bandwidth, realize taking full advantage of of configured bandwidth, and realized the allocated bandwidth of Priority-based, thereby effectively promoted user's experience.
