Embodiment 1

[0050] as attached figure 1 As shown, it is a schematic flowchart of a method for obtaining a resource device address provided in Embodiment 1 of the present application. This method 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 can be a router or a layer-3 switch. The specific steps of the method are as follows:

[0051] Step 101, receiving the 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, and 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 a specific application scenar...

Embodiment 2

[0089] Embodiment 1 expounds the process of the resource device address acquisition method from the perspective of the gateway device. Correspondingly, this application also explains from the perspective of the management platform VM. This method is applied to resource devices, management platform VMs and multiple gateways. For the VM in the device network, 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 obtained when the resource device and the VM are not in the same network segment The above VM is generate...

Embodiment 3

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

[0169] A receiving module that receives a first address request message generated by the VM, where 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] Judging module 61, judging whether the IP address belongs to the network segment where the IP address is located;

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

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...
