Abstract

The invention discloses an identification method for application layer protocol characteristics, comprising the following processes: capturing a flow packet, selecting an identification mode, pretreating the flow packet, combining a characteristic set in a characteristic database to identify current network flow and displaying an identification result. The characteristic set in the characteristic database is updated timely by adopting a set of data mining AC algorithm based on an Apriori algorithm, thereby improving the accuracy of identifying the application layer protocol, overcoming various disadvantages of identifying network protocols by the traditional manual analysis method, promoting the informatization and intellectualization of application layer protocol analysis work for enterprises and companies, reducing labor source load for enterprises and companies and improving work efficiency and rate of progress.

Description

technical field

[0001] The invention belongs to the technical field of the Internet, and in particular relates to a system and method for identifying protocol features of an application layer. Background technique

[0002] With the gradual development of the Internet, online users and business traffic are constantly increasing. In addition to traditional data services, emerging services such as P2P, online games, and IPTV occupy most of the bandwidth of the Internet. On the one hand, there are problems with the service quality of operators. On the other hand, it also makes the basic network construction of operators fall into the abnormal situation of "congestion-expansion-re-congestion", and the profitability is correspondingly reduced.

[0003] In the same network, if some users seriously occupy the bandwidth for online games, BT downloads and other activities, it will affect the normal use of network resources by others, or affect the work of others. After all, the devel...
