System and method for dynamically setting qos based on deep packet inspection

Abstract

The present invention relates to a system and method for dynamically generating Qos policies based on deep packet inspection in a home gateway. The system includes a deep packet inspection module and a server database, and the server database is regularly updated according to a priority server setting rule, which includes priority server, and the system screens through the deep packet inspection module whether the IP data packets currently passing through the deep packet inspection module include the same IP address as the priority server in the regularly updated server database, and the home gateway according to the screening The Qos policy is set for the outgoing IP address, and the Qos policy is to set the priority of the IP address as high. When the comparison finds that there is no IP address included in the priority server library, the router deletes the Qos policy. By adopting the system and method for dynamically generating Qos policies based on deep packet inspection in the home gateway, Qos policies can be dynamically generated according to the dynamically obtained priority server list, so as to realize the realization of the Qos function in the case of zero configuration.

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.
