Terminal equipment and network flow calculation method and system based on terminal equipment

Abstract

The invention discloses terminal equipment and a network flow calculation method and system based on the terminal equipment. The method comprises that a network data packet through a network driving interface standard intermediate layer is grabbed; protocol analysis is carried out on the grabbed network data packet is according to a preset protocol set, and protocols used by the grabbed network data packet are obtained; the header of the grabbed network data packet is parsed by utilizing the obtained protocols, and flow of the grabbed network data packet is obtained; and the sum of flows of all grabbed network data packets is calculated to obtain the network flow of the terminal equipment. Thus, the calculation error of the network flow can be reduced, and the calculation precision of the same is improved.

Description

technical field [0001] The invention relates to a network traffic statistics technology, in particular to a terminal device, a terminal device-based network traffic statistics method and system. Background technique [0002] Network traffic management can achieve the optimal use efficiency of network resources by rationally configuring the overall network architecture. Therefore, as an important means of effectively configuring network resources, it is widely used. Among them, the network traffic management system based on the network traffic statistics of terminal equipment can effectively avoid the abuse and waste of network resources and ensure the security of the network system through real-time monitoring of the operating status of each terminal equipment in the current network and implementation of traffic policy control. Normal operation is an effective method for enterprises to realize IT management and process control. [0003] At present, the terminal device-based...

Problems solved by technology

Among them, the intranet traffic belongs to the network traffic without payment, and the existing network traffic statistics method does not distinguish between intranet traffic and external network traffic, which increases the Internet access cost of users or enterprises; moreover, some operating systems of terminal equipment Shared files, due to the special processing method used in the file sharing function, after receiving at the network card layer, or after sending at the application layer, you can directly skip the connected flow control driver to send and receive network data packets, so , the network traffic consumed by this part of network packets cannot be effectively counted, making the reliability of traffic statistics low

For example, after testing, it was found that the existing network traffic statistics method based on terminal equipment, because the Windows operating system has carried out special processing on the realization of the file sharing function, directly skipped the flow control driver to send and receive network data packets, therefore, it is impossible to The uploading and downloading traffic of shared files in the windows system is used for traffic statistics and control, which makes the traffic reliability provided to terminal equipment users poor.
