Embodiment 1
[0043] Before performing flow control, the user first determines the protocol that needs to be flow controlled. The control strategy can distinguish different protocols / applications, and can set the preset threshold of each protocol flow. The user can also set different presets in different time periods. Set a threshold to use bandwidth more effectively. Protocol analysis is the premise of the present invention, but it does not belong to the scope of the present invention. After the protocol has been identified, the present invention can effectively and accurately control the protocol flow of the multi-connection characteristic.
[0044] The flow control method of this embodiment adopts the bypass access mode, and its network topology is as figure 1 As shown, in the bypass access model, the network monitoring device of this embodiment (ie figure 1 In the flow control system) is in the middle of the internal / external network, but independent of the two. All data of internal / exter...

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. Specifically, the invention relates to a flow control method. Background technique [0002] With the rapid development of Internet services, network traffic has increased dramatically, and network applications continue to emerge, and their application forms have also shifted 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 lot of bandwidth. Statistical analysis shows that P2P applications account for about 50%...
