Problems solved by technology

But on the other hand, some enterprises and companies that apply and analyze application layer protocols have put forward the need to analyze application layer protocols and obtain corresponding protocol features, while existing network traffic control products only provide traffic control functions and do not provide Methods and Interfaces for Application Layer Protocol Extraction and Analysis Functions
Moreover, if specialized personnel are hired to manually analyze the characteristics of the application layer protocol, it will affect work efficiency and progress, and bring a burden on human resources to enterprises and companies.

Embodiment 1

[0046] Embodiment one, see figure 1 As shown, the application layer protocol feature recognition method of this embodiment is mainly designed and implemented by the following steps:

[0047] Step1. Set the usage authority and manage the safe use of the system;

[0048] Considering the security of the system, this embodiment preferably verifies the legal identity of the login user before the system runs normally, that is, requires the user to enter the user name and password for identity verification, and then verifies the user according to the pre-saved authority information Whether the entered user name and password are correct, if the user name and password match the saved permission information, the user passes the verification and enters the system; if the user name or password is wrong, the user is reminded to confirm whether the entered user name or password is correct, and ask again The user enters the user name and password until the authentication is passed, and then...

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 characteristicdatabase 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...
