Problems solved by technology

[0005] However, it takes a lot of system resources to perform feature detection for each data packet. After feature detection is turned on, the forwarding efficiency of the device will be reduced, and the performance of the device will be affected, which in turn will affect the use of users.
[0006] Moreover, the gateway device does not know when to turn on the feature detection. If the time to turn on the feature detection is too long, it will waste system resources and affect the normal use of users. If the time to turn on the feature detection is wrong, the P2P application cannot be detected and corresponding control

Embodiment Construction

[0063] In the present invention, by counting the number of NAT connections and / or the size of the traffic in real time, when it is judged according to the number of NAT connections and / or the size of the traffic that it is necessary to perform feature detection on the detected traffic, it is necessary to perform feature detection on the detected traffic, thereby realizing feature detection The automatic opening and closing process of the device makes reasonable use of resources such as the CPU and memory of the device, and while realizing the control of applications such as P2P, the forwarding efficiency of the device is maintained through the method of layered and step-by-step detection, which reduces the time when the feature detection is turned on. The impact on the forwarding performance of the device, and the ability to monitor the P2P characteristics of abnormal traffic when users surf the Internet, ensure the intelligence of network devices such as gateways, improve user ...

Abstract

The invention discloses a flow control method. The method comprises the following steps of: counting a network address translation (NAT) connecting number and / or a flow magnitude; judging whether carrying out feature detection on a detected flow is needed or not according to the NAT connecting number and / or the flow magnitude; and when a judging result indicates that the feature detection is needed to be carried out on the detected flow, opening the feature detection for the detected flow. The invention improves the use experience of users and reduces the use and maintenance difficulty.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a flow control method and device. Background technique [0002] Today's Internet has entered every aspect of people's work and life, and there are more and more applications on the Internet. Among Internet applications, P2P (Peer-to-Peer, point-to-point) applications (such as Thunder, BT, etc.) While greatly enriching people's lives, it also consumes a lot of network resources. It can be seen that due to the large number of P2P applications, the user's Internet access speed will slow down, and affect the user's normal office or Internet access. [0003] In order to solve the above problems, network equipment manufacturers need to control P2P applications, but due to the uncertainty of network server locations (IP addresses) and the diversity of P2P application software, it is impossible to use the method of restricting network server addresses when controlling P2P ...
