Below in conjunction with Figure of description, technical solution of the present invention is described in detail.

See Fig. 1, for being the method flow diagram of distribution of flows resource in the embodiment of the present invention, the method comprises:

Step 101, for each transmission path, determine data traffic volume in current period of each data flow in this transmission path and data request amount.

Step 102, according to the data traffic volume of data flow each in described transmission path and data request amount, determine that the data of this transmission path in current period send total amount and request of data total amount.

Step 103, send the distribution bandwidth of total amount and data request amount, this transmission path in the data of current period at the data traffic volume of current period and data request amount, transmission path according to each data flow, determine that in this transmission path, each data flow is in the data request amount in next cycle.

Preferably, for ensureing that each data flow be linked in transmission path has sufficient bandwidth to carry out transfer of data, above-mentioned flow process also comprises:

Step 104, the data flow access request received on transmission path, and when according to the guarantee bandwidth sum of the data flow of request access, the idle bandwidth of transmission path is determined to access described data flow, for the distribution of flows of this request access ensures bandwidth accordingly from the idle bandwidth of described transmission path.

In above-mentioned process step 102, determine that the data of this transmission path in current period send total amount and request of data total amount, comprise: the data traffic volume of all data flow in this transmission path in current period added up, the accumulated value obtained is the data of this transmission path in current period and sends total amount; The data request amount of all data flow in current period in this transmission path added up, the accumulated value obtained is the request of data total amount of this transmission path in current period.
