Network flow control 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. 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%...

Problems solved by technology

In the existing TCP traffic bypass blocking technology, its traffic calculation only considers the information provided in the currently arriving data packet, which cannot well reflect the average traffic over a period of time

And in the existing method, as long as the traffic exceeds the preset threshold, it will be directly blocked, which is very likely to block most of the connections at once. If this continues, it will inevitably cause large fluctuations in traffic. For effective bandwidth also a waste

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
