Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The present invention aims to provide a passive device type identification method to deal with the discovery, identification and management of a large number of various types of devices in the Internet of Things era. By detecting normal network communication in the local area network, the application technology and implementation principle of the present invention will be explained below:

[0025] DHCP protocol identification

[0026] DHCP (Dynamic Host Configuration Protocol) is usually used in large-scale LAN network environments, mainly for the dynamic allocation, management, and recycling of IP addresses, so that various types of smart devices, mobile devices, and IT assets based on the network can be dynamically configured. Obtain information such as IP address, gateway, DNS server, WINS server, etc. The DHCP protocol adopts the model of cl...

Abstract

The invention discloses a local area network equipment type identification method. The method comprises the following specific steps: analyzing received message content of a DHCP protocol sent by a client; identifying the equipment terminal type of the client by utilizing the parsed message information; if not, providing a short-time available address for the client, and guiding the gateway flow of the client at the same time; analyzing the network protocol stack and the application flow of the client, and determining identification features of the client; matching the equipment type of the client according to the type identification feature library through the identification features of the client, and meanwhile, enabling the DHCP server to synchronize the new lease information to the client, so that the network flow of the subsequent client is not guided any more; and updating the client identification features in the type identification feature library. According to the invention, the possible influence on the network bandwidth of the local area network in the active detection process and the number of detection messages in the local area network are reduced, and the invasion tothe network is reduced as much as possible.

Description

technical field [0001] The invention relates to a device type identification method, in particular to a local area network device type identification method. Background technique [0002] With the rapid popularization and promotion of various types of smart devices, mobile devices and terminal devices, the trend of IT consumerization is becoming more and more obvious. More and more people benefit from mobile devices, smart devices and various With the convenience and speed of terminal devices, more and more employees of enterprises and government units also hope to add more mobile and smart device terminals to their daily office to simplify their work processes. BYOD (Bring Your Own Device), as an important manifestation of IT consumerization, not only brings convenience to enterprises, but also brings huge threats and challenges to the original network security management. [0003] Theoretically speaking, the communication process of all smart devices, mobile devices and t...
