[0039] Please refer to image 3 , image 3 This is one of the flow charts of the steps of the method for accessing the network device 300 based on the same IP address provided by the first embodiment of the present invention. The method is applied to the server 100 communicatively connected with the client 200 and multiple network devices 300 with the same IP address.

[0040] In this embodiment, the server 100 stores the corresponding relationship between the real IP address of the network device 300, the virtual IP address of the network device 300, and the physical address of the network device 300, wherein each of the network devices 300 The virtual IP address of the network device 300 is defined by the interface of the server 100 connected to the network device 300 .

[0041] In this embodiment, the IP address (Internet Protocol Address, Internet Protocol Address) is an abbreviation of IPAddress. The IP address is a unified address format provided by the IP protocol. I...

Abstract

The invention provides a network device access method and apparatus based on the same IP address. The network device access method and apparatus are applied to a server in communication connection with a client and a plurality of network devices having the same IP address. An access message sent by the client is received. An access destination IP address (the virtual IP address of the network devices) in the access message is replaced with the real IP address of the network devices based on a network device access corresponding relation, and the replaced access message is sent to the network devices through physical addresses of the network devices. Therefore, the client can simultaneously access a plurality of network devices having the same IP address in the same network without frequently modifying the access configuration, and thus the access and test efficiency can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of communication access, in particular to a method and device for accessing network equipment based on the same IP address. Background technique [0002] Network devices (for example, NVR-Network Video Recorder, network hard disk video recorder) are configured with default factory addresses when they leave the factory, and these devices need to conduct batch pre-factory inspection tests before they are officially put into use in the market, so as to be able to find out the location of the product. Defects and timely optimization to better meet customer needs. [0003] In the prior art, by connecting the network equipment (for example, NVR) to the same switch, and then connecting it with a PC, accessing each network equipment through PC Telnet, to test whether the function of each network equipment exists abnormal. When a PC accesses a network device, the switch interface connected to the network de...
