Problems solved by technology

[0006] It can be seen that the existing token bucket flow control method can accurately control the flow of identified data packets, but the unidentified data packets cannot be counted in the control flow due to direct forwarding, and due to multiple The establishment of multiple data streams, the alternation of the aging status between data streams, etc., resulting in the actual flow passing through more than the set value of the flow control, and the flow control is not accurate

Abstract

The present invention provides a flow control device, which controls data transmission flow based on a token bucket algorithm. The device includes: a type identification unit, which is used to identify the protocol type of each data packet in a data flow; unit, used to directly forward the data packet that cannot be identified by the type identification unit; an information recording unit, used to record the data flow of the unidentified data packet; a token update unit, used to use the unidentified data packet The number of tokens required for the data traffic, and the total amount of tokens in the token bucket is updated. The invention also proposes a flow control method. Through the technical scheme of the invention, flow statistics and control can also be performed on unidentified data packets in the data flow, thereby more accurately realizing the flow control of the application protocol.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a flow control system and a flow control method. Background technique [0002] Smart pipeline technology has become the development trend of the Internet. Smart pipelines are based on in-depth analysis of network traffic to achieve visibility, controllability, and operability of Internet pipeline traffic. DPI equipment plays a vital role in the construction of intelligent pipelines. DPI equipment needs to realize precise control of traffic content on the basis of traffic content analysis. [0003] The token bucket algorithm is a commonly used algorithm for DPI devices in traffic management and control. It monitors the traffic rate entering the network port and discards the excess traffic, thereby limiting the traffic passing rate. For example, limit the P2P traffic rate to within 100M. [0004] Such as figure 1 As shown, the flow size of data packets that need...
