Problems solved by technology
The advantage of using the port identification method is that the application corresponding to the data flow can be identified only through the port, and the system burden is small; When the port is not fixed, the network egress device cannot accurately identify the application (such as P2P application). For example, for an unknown port or a port corresponding to multiple applications, the network egress device will also have a serious misjudgment. be able to accurately identify the application

Embodiment Construction
[0027] In the local area network environment, in order to improve the accuracy of application identification under the premise of reducing the operating load of the network egress device, in the embodiment of the present invention, when the intranet host starts the executable file, it obtains the executable file according to the file attribute of the executable file. File identification information; the intranet host matches the obtained file identification information with a preset executable file feature library to obtain a matching result, and the executable file feature library is used to record the relationship between the file identification information and the application type Correspondence: the intranet host determines the application type of the executable file according to the matching result, and when at least one data flow interacting with the Internet is generated during the execution of the executable file, the at least one A message identification information of...

The invention relates to the internet technology, and discloses an application program identification method for improving the accuracy of the application identification under the premise of reducing the running load of the network exit equipment. The method comprises the following steps: on the basis of a matching result of file identification information of an executable file and a preset executable file feature library, the internal host determines the application type of the executable file, analyzes the report identification information of a data stream generated by the executable file, and reports the application type and the report identification information to the network exit equipment, the network exit equipment establishes a stream node corresponding to the report identification information of the data stream, and sets priority and flow control policy of the stream node based on the application type of the executable file. Consequently, the judgement of the application of the data stream can be made accurately and rapidly, and the running load of the network exit equipment is reduced greatly. The invention also discloses an internal host and a local network system for the application program identification.
Description
technical field [0001] The invention relates to Internet technology, in particular to an application program identification method, device and system. Background technique [0002] At present, in the LAN network environment, the egress bandwidth is usually limited, and there are often one or several application programs that need to be optimized to ensure smooth operation in each LAN network. For example, in the enterprise local area network, it is necessary to give priority to ensuring the fast operation of enterprise management software, financial software and other applications to ensure the rapid transmission of information; while in the Internet cafe local area network, it is necessary to give priority to ensuring the smooth operation of online games and other applications . [0003] It can be seen that no matter what kind of LAN network environment, it is necessary to reduce the consumption of egress bandwidth by P2P applications as much as possible, and in order to a...
