Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0029] The layered mechanism of the TCP / IP protocol makes the layer 3 data packets not contain the layer 2 information. Therefore, the IP address of the data packets forwarded by the layer 3 can only be roughly located in the IP range, and cannot be accurately located in the access layer. port. For access management and information security information source location and tracking, the precise location of the second layer is very valuable. Accurate IP positioning of the entire network is a problem that has plagued the industry for a long time, and the present invention can effectively solve this problem.

Abstract

The invention discloses an IP accurate positioning system and method. The system comprises access control modules, client modules, an agent module and a control center module, wherein the access control modules acquire the MAC of terminal addresses and a port of a switch, the MAC of the terminal addresses, the port of the switch, the identification WID of an access layer switch, the identification SID of the access control modules are made to form corresponding relation information MAC-PORT-WID-SID, and the MAC-PORT-WID-SID is transmitted to a control center; the client modules are used for transmitting heartbeat information to the agent module; the agent module is used for managing the online states of all terminals according to the heartbeat information transmitted by all the client modules and transmitting the corresponding relation information IP-MAC to the control center module in real time; the control center module is used for acquiring the MAC-PORT-WID-SID from all the access control modules, acquiring the IP-MAC from the agent module and correlating and storing the MAC-PORT-WID-SID and the IP-MAC to form five-side online data.

Description

technical field [0001] The invention relates to the technical field of network access control and security, in particular to an IP request positioning system and method. Background technique [0002] The basic TCP / IP protocol of Ethernet is a seven-layer hierarchical structure. Layer 7-1 is from top to bottom. The upper-layer data packets are encapsulated in the lower-layer data packets. On the contrary, the upper-layer data packets do not contain the lower-layer attributes, such as: three-layer data packets The TCP that encapsulates the four-layer data packet with IP, conversely, the four-layer data packet only contains the TCP attributes of this layer, and does not contain the IP attributes of the third layer; The layer data packet only has IP and does not contain the MAC information of the second layer. IP is in the third layer of the seven-layer structure, so IP-based network positioning can only be performed on the third layer. Most of the access layer of the existing...
