Abstract

The invention provides a flow management device and a method for saving a cache resource. The flow management method comprises the following steps of: setting a read command cache; sending read commands to the cache; reading the read commands according to a first-in first-out sequence, reading data according to the read commands to a queue to which a storing outbound line side module sends the data; judging whether the read command stored by the cache reaches a preset threshold value; and stopping sending the read command if the preset threshold value is reached, and continuously reading the read command in the cache according to the first-in first-out sequence. The flow management device and the method reduce cache usage in a flow management system.

Description

technical field [0001] The invention relates to the field of flow management, because it relates to a flow management device and method for saving cache resources. Background technique [0002] In the field of data communication, the demand for the quality of service of data products is getting higher and higher, so the demand for traffic management functions is also getting higher and higher. [0003] The structure of the existing traffic management system is as follows: figure 1 As shown, it includes an incoming line-side module, an outgoing line-side module, a queue management module, a cache management module, and a data storage module. The data from the inbound line module is written into the data storage module, and the queue management module reads the data in the data storage module and sends it to the outbound line side module. Due to the limited cache resources of the outbound line-side modules, it is necessary to perform flow control on the output data of the qu...
