Network flow detection method

Abstract

The present invention provides a network flow detection method, and comprises the following steps: a) adopting a flow control system to calculate the average rate of protocols according to the historical information of the protocol of the data packet and the information carried by the data packet; b) judging whether the data packet of the protocol should be controlled according to the average rate of protocols, which is calculated in the step a); and c) controlling the data packet which satisfies the control condition. Compared with the prior art, the method has the following advantages: the rate estimation algorithm based on the historical time window is adopted to accurately calculate the rate of the current protocol flow; the flexible and convenient configuration can be used for simultaneously controlling a plurality of protocols which are combined freely; the efficiency of the system is improved; only the protocol to be controlled needs processing, while others need no processing; the bypass type access brings convenience and can not form network bottlenecks; the system is simple and can be easily realized; and the system can achieve the accurate flow control.

Description

technical field [0001] The invention belongs to the field of network technology, in particular, the invention relates to a flow detection method. Background technique [0002] With the rapid development of Internet services, network traffic increases sharply, network applications continue to emerge, and their application forms are shifting from traditional services such as FTP and Web to P2P and Web2.0. At the same time, this trend has also caused some problems, for example, the P2P applications that have emerged in recent years have greatly consumed limited network resources. [0003] P2P is a distributed network that breaks the traditional Client / Server (C / S) model, and the status of each node in the network is equal. Each node not only acts as a server, provides services for other nodes, but also enjoys the services provided by other nodes. However, P2P applications occupy a large amount of bandwidth. Statistical analysis shows that P2P applications account for about 50...

Problems solved by technology

[0006]The current bypass access control technology is not yet relatively mature. In addition to the shortcomings in flow detection, in existing methods, as long as the flow exceeds the preset threshold, Just block it directly, which is very likely to block most of the connections at once. If this continues, it will inevitably cause large fluctuations in traffic, which is also a waste of effective bandwidth

Furthermore, the configuration of the existing traffic control strategy is not flexible and comprehensive enough

Therefore, there is still a large room for improvement in the existing TCP flow control
