Embodiment Construction

[0017] Such as figure 1 As shown in the video surveillance network diagram, the surveillance network includes an encoding terminal 11 (such as an encoder EC and an IP camera IPC), a surveillance management server VM12, a media server MS13, a relay device 14, a network device 15 and a DHCP server 16. All encoding terminals 11 are located in the same layer-2 network, and the relay device 14 serves as a layer-3 gateway for all encoding terminals 11 . Another three-layer network includes monitoring and management server VM12 and media server MS13. DHCP server 16 is located in yet another layer-3 network. Wherein the relay device 14 logically includes an IP address request processing module 21, an identity processing module 22, a DHCP relay module 23, and an address information processing module 24, see figure 2 .

[0018] Step 11: After the encoding terminal is powered on, it broadcasts a DHCP Discovery message, and the DHCP Discovery message carries the identifier of the enco...

Abstract

The invention provides a method for automatically assigning internet protocol (IP) address. The method comprises the following steps: receiving a dynamic host configuration protocol (DHCP) discovery message transmitted by an encoding terminal by using relay equipment; transmitting terminal equipment identification information in the message to a monitoring management server, so that the monitoring management server can perform legality judgment on the coding terminal; receiving the legality result fed back by the monitoring management server; if the coding terminal is legal, transmitting the DHCP discovery message to a DHCP server in the network, and if the coding terminal is illegal, forbidding transmitting the DHCP discovery message to the DHCP server; and receiving the DHCP message transmitted by the DHCP server to the coding terminal and transmitting the DHCP message to the coding terminal, wherein the DHCP message carries the IP address assigned by the DHCP server to the coding terminal. The coding terminal realizes zero configuration, so the configuration work of an administrator on a large amount of terminal equipment is saved. Due to the existence of the authentication process of the coding terminal, illegal coding terminal cannot be on line.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method for automatically assigning IP addresses to terminal devices in a monitoring network. Background technique [0002] The current video monitoring system generally has IP network bearer, video encoding front-end equipment (such as encoder EC, network camera IPC), monitoring management server (such as VM), back-end monitoring equipment (such as decoder DC, monitoring client VC) Located in various locations of the IP network. To realize the normal operation of the monitoring network, generally each device in the monitoring network needs its own IP address and MAC address, so as to realize the communication between these devices based on IP network communication protocols (such as Layer 2 communication protocol and Layer 3 communication protocol). Normal communication. [0003] Currently, for front-end encoding terminals, static configuration is generally used to e...
