Abstract
The invention discloses a network adaptive operation mode on a network monitoring system. The network monitoring system comprises monitoring equipment, client equipment and a server, wherein the operation modes of the network monitoring system comprise: detecting IP addresses and network environments of the monitoring equipment and the client equipment and selecting a communication mode of a signaling and a video according to the network environments of the monitoring equipment and the client equipment. Only when the monitoring equipment and the client equipment are in an impenetrable intranet environment, the communication mode of forwarding the signaling and the video by using a forwarding server is selected; and in other situations, a server assists the monitoring equipment and the client equipment in establishing a signaling channel for data exchange and establishing a video channel for connecting the monitoring equipment and the client equipment according to the signaling channel. The network adaptive operation mode has the advantages of not only realizing plug and play of network security protection monitoring equipment, but also saving the cost of installation, maintenance and operation.
Description
Technical field
The present invention relates to a kind of P2P pattern of network, especially relate to the network self-adapting operational mode on a kind of non-maintaining network monitoring system.
Background technology
Existing traditional network monitoring generally all will arrange dns server, mapped port, and the IP address does not have NAT to penetrate function, and just there has been following shortcoming in it so:
1, installation personnel need to be familiar with network knowledge, the correct configuration network parameter of ability and dns server, and installation cost is larger.
2, in use the user has changed network environment, generally needs technical support personnel's assistance or installation personnel to make house calls, and could allow equipment adapt to new network environment, and cost of serving is larger.
3, by the even free Ddns server of third party, could realize Telnet and browsing video, affect Systems balanth.
4, configuration upnp port on the nat of equipment end, because can only the assigned ip towards the internet be used, arrange complexity and cause equipment normally not move in multistage nat network environment.
5, can not automatically select the network mode of operation of equipment according to equipment and the residing network environment of client, conditions for equipment use is limited.
If 6 equipment and client are all come transmitting signaling and passage with forwarding server, need to set up numerous servers, the cost of foundation and maintenance server is expensive.
Summary of the invention
For problem set forth above, the network self-adapting operational mode when the object of the present invention is to provide the plug-and-play feature of network monitoring device on a kind of network monitoring system on the network monitoring system of reduce installation, maintenance cost and server and network bandwidth cost.
The present invention realizes by following technical measures, network self-adapting operational mode on a kind of network monitoring system, network monitoring system comprises watch-dog, client device and server, its operational mode comprises the steps: the IP address of watch-dog and client device and the detection of network environment, selects the communication mode of signaling and video according to the network environment of watch-dog and client device; Wherein,
