Problems solved by technology

[0004] (1) In the prior art, most resource devices rely on the DHCP function of the network to obtain IP addresses. When the resource device reconnects to the network after being disconnected, the IP address of the reconnected resource device may change. Register/keep alive with the platform device again, but the platform will consider the IP address as a new IP address, and the resource device is not the original device, which will lead to errors such as the failure of the device to go online;
[0005] (2) Simply using the IP address as the identification resource device cannot effectively prevent other devices from pretending to be the IP address of the existing resource device to maliciously attack the current video surveillance system network;

Example Embodiment

[0049] Example one

[0050] As attached figure 1 As shown, a schematic flow diagram of a method for obtaining an address of a resource device provided in Embodiment 1 of this application is applied to a gateway device in a network including a resource device, a management platform VM, and multiple gateway devices. It should be noted that, The gateway device in the embodiment of the present application refers to a network device that has a routing function and contains a certain network segment. Specifically, it may be a router or a Layer 3 switch. The specific steps of the method are as follows:

[0051] Step 101: Receive a first address request message generated by the VM;

[0052] The first address request message carries the address request identifier and the IP address of the resource device. The address request identifier and the IP address are generated when the resource device and the VM are not in the same network segment.

[0053] In specific application scenarios, there are ...

Example Embodiment

[0088] Example two

[0089] The first embodiment illustrates the process of obtaining the address of the resource device from the perspective of the gateway device. Correspondingly, this application also describes the method from the perspective of the management platform VM. The method is applied to the resource device, the management platform VM and multiple gateways. For the VM in the network of devices, the first gateway device where the resource device is located is in the first network segment, and the second gateway device where the VM is located is in the second network segment.

[0090] Such as figure 2 As shown, the method includes the following steps:

[0091] S201: Send a first address request message to the first gateway device.

[0092] The first address request message carries an address request identifier and the IP address of the resource device, and the address request identifier and the IP address are used when the resource device and the VM are not in the same net...

Example Embodiment

[0167] Example three

[0168] Correspondingly, this application also proposes a resource equipment address acquisition device, such as Image 6 Shown here is a schematic structural diagram of a device for obtaining an address of a resource device according to an embodiment of the application. The device is applied to the gateway device in a network including a resource device, a management platform VM, and multiple gateway devices, and the device includes:

[0169] The receiving module receives a first address request message generated by the VM, the first address request message carries an address request identifier and the IP address of the resource device, and the address request identifier and the IP address are Generated by the VM when the resource device and the VM are not in the same network segment;

[0170] The judging module 61 judges whether the IP address belongs to the network segment where it is located;

[0171] The first sending module 62, if the IP address does not be...

Abstract

The invention discloses a resource device address obtaining method and device. The method is applied to gateway devices in a network. The network comprises a resource device, a management platform VM and multiple gateway devices. An address request message generated by the management platform VM according to a resource device IP address is received; whether an IP address in the address request message belongs to a network segment in which the resource device is located or not is judged according to an address request identifier in the address request message; an address response message is generated according to an MAC address corresponding to the IP address and a target network segment in which the resource device is located when the IP address in the address request message belongs to the network segment in which the resource device is located, and the address response message is sent to the VM, so when the VM and the resource device are located in different network segments, the VM still can obtain the network address information of the resource device accurately, processes such as initial access and post-maintenance of the resource device become more simple and convenient.

Description

technical field [0001] The present invention relates to the technical field of network address acquisition, in particular to a resource device address acquisition method and device. Background technique [0002] In the video surveillance system network, there are generally roles such as monitoring platform, network camera IPC, network equipment, and network hard disk video recorder NVR. The platform is the core node and is responsible for the access, management, and business scheduling of all resources. Resource devices such as NVR / IPC / social resources are connected to the monitoring system through various monitoring protocols, such as the onvif (Open Network Video Interface Forum) protocol as an example, the management platform VM determines a resource device through a unique IP address, and performs For services such as registration management, after the device goes online successfully, each resource device corresponds to an IP address. [0003] However, in practical appl...
