Problems solved by technology

[0003] However, in the case of data transmission link congestion, the existing bandwidth setting methods usually allocate bandwidth to high-priority data flows first, and then allocate bandwidth to low-priority data flows, resulting in low-priority data flows being long Time cannot be used for data transmission, therefore, there is a problem of unreasonable bandwidth allocation

Abstract

The application discloses a bandwidth setting method, device and system. A specific embodiment of the method comprises the following steps: acquiring a bandwidth overflow value of a data transmission link, wherein the bandwidth overflow value is the difference value between the bandwidth occupied by the data transmission link and a preset maximum allowable occupied bandwidth; acquiring the bandwidth occupied by each data flow in the data transmission link, and determining the priority of each data flow; re-distributing the bandwidth for the data flows in the data transmission link according to the bandwidth overflow value, the bandwidth occupied by each data flow and the priority of each data flow, and generating bandwidth distribution information corresponding to the data flows, wherein the bandwidth distribution information comprises a bandwidth distribution instruction; and respectively sending the bandwidth distribution information corresponding to the data flows to clients corresponding to the data flows so that the client can set the bandwidth for each data flow in the data transmission link according to the bandwidth distribution instruction. Through the adoption of the method, device and system disclosed by the embodiment, the effective and reasonable bandwidth distribution is realized.

Description

technical field [0001] The present application relates to the field of network technology, in particular to the field of network data transmission, and in particular to a bandwidth setting method, device and system. Background technique [0002] With the rapid development of the network, the number of network users has increased sharply, and the amount of network data is huge, which poses a great challenge to network data transmission. A data transmission network usually consists of multiple data transmission links, and the huge amount of data will cause some data transmission links to be congested. At this time, it is necessary to reset the bandwidth occupied by the data streams in these data transmission links. [0003] However, in the case of data transmission link congestion, the existing bandwidth setting methods usually allocate bandwidth to high-priority data flows first, and then allocate bandwidth to low-priority data flows, resulting in low-priority data flows bein...
