Problems solved by technology

When the downlink sends packets at wire speed, the uplink is bound to be congested, causing some data streams to fail to be forwarded normally.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0024] The flow control group system provided by the present invention includes a flow control group generating module and a flow control group monitoring module.

[0025] Among them, the flow control group generation module: used to set the uplink as the reference group and the downlink as the passive group; set the bandwidth threshold value of the flow control group; and set each downlink in the passive group according to the importance of the link The authority value of the link, the more important the link, the greater the authority value.

[0026] Flow control group monitoring module: used to monitor the link bandwidth of the reference group and the passive group; when the bandwidth difference between the two is less than the bandwidth threshold value of the flow control group, close some downlinks with relatively low authority values ​​in the p...

Abstract

The invention discloses a flow controlling system for controlling flow balance and the controlling method thereof. The controlling method comprises: (1) setting the upper route as base group and the lower route the passive group; and set the bandwidth limitation; (2) monitoring the bandwidth of the base group and the passive group in real time, reducing the bandwidth of the passive group to bandwidth limitation if the difference of the two bandwidth is smaller than the bandwidth limitation; increasing the bandwidth of the passive group until equal to bandwidth limitation. In the invention based on the existing switching instrument, a flow controlling group for controlling the bandwidth balance of the upper and lower route is added, which realizes the flow balance and avoids losing forwarddata packet when congestion happens. And the invention is based on the existing hardware instrument, so no additional cost of hardware is needed and the additional cost of software is not big.

Description

technical field [0001] The invention relates to the flow balance problem in the network data exchange process, in particular to a flow control group system for controlling flow balance and a control method thereof. Background technique [0002] With the rapid development of information technology, the composition of the network is becoming more and more complex. In a real network, network data exchange is generally divided into uplink and downlink data links. The uplink data link generally goes to the service network, and the downlink data link generally reaches the user. Once the uplink is congested, data forwarding is bound to have problems. [0003] Since the existing equipment does not take into account the control of the balance of uplink and downlink data, once the uplink is congested, the network services of some important customers will not be able to operate normally. [0004] First, if figure 1 As shown, if a new downlink is added to device 1, the bandwidth of ...
