Dynamic QoS setting system and method based on deep packet inspection

Abstract

The invention relates to a dynamic QoS policy generation system and method based on deep packet inspection in home gateway. The system comprises a deep packet inspection module and a server database, wherein the server database timely updates an included preferred server according to a preferred server setting rule; the system utilizes the deep packet inspection module to screen whether the current IP data packet passing through the deep packet inspection module has the same IP address as the preferred server timely updated by the server database; and the home gateway sets a QoS policy according to the screened IP address, and the QoS policy is: setting the priority of the IP address to be high. When no IP address included in the preferred server database exists after screening, a router cancels the QoS policy. By utilizing the dynamic QoS policy generation system and method based on the deep packet inspection in the home gateway, the QoS policy can be dynamically generated according to the dynamically acquired preferred server list, and then a QoS function under a zero configuration condition is achieved.

Description

technical field [0001] The present invention relates to bandwidth dynamic distribution strategy technology, in particular to bandwidth dynamic Qos distribution strategy technology, specifically a system and method for dynamically generating Qos strategy based on deep packet detection in a home gateway. Background technique [0002] At present, network communication is popularized to every household, and there are many kinds of online applications, which inevitably leads to network congestion. Some of these applications, such as large-scale online games, webcasting, and video functions of communication tools, etc., are characterized by data interaction in which the bandwidth required for data interaction is not large, but they are sensitive to delay and packet loss and require stable bandwidth. On the contrary, some download types such as Thunder download, BT download, and data interaction of bufferable video do not require high bandwidth stability. Therefore, make correspon...

Problems solved by technology

[0004] (1) For users who are not familiar with communication principles, it is very difficult to configure QoS applications, and they do not even know the existence of this function;

[0005] (2) The QoS function of the home gateway is single. The more common QoS strategy is to limit the speed according to the user. The disadvantage of this strategy is that there will still be network congestion between different applications of the same user, and bandwidth utilization cannot be realized between different users. Maximize, it is easy to cause bandwidth waste;

[0006] (3) For users who are familiar with communication principles, to formulate an application-specific QoS plan, it is necessary to obtain the latest data of the application and do a large amount of data analysis, so it is still difficult to configure QoS;

[0007] It can be seen that traditional QoS functions have defects such as difficult configuration, single function, and waste of bandwidth.
