Equipment agent device and network management device

Abstract

The utility model provides an equipment agent device and a network management device. The equipment agent device and the network management device can achieve managing network across network address translation (NAT). The main achieving steps of the equipment agent device and the network management device includes that a long connection request is initiated for a pre-opened transmission control protocol (TCP) port to build a control TCP long connection, agent request order is commanded to controlled equipment through the TCP long connection and carries a business TCP port number distributed by a controlling device, the controlled equipment initiate the TCP connection to the business TCP port to build a business TCP connection and build a local connection with local management business units of the controlled equipment, the controlling device sends management request to the controlled equipment through the business TCP connection, and the controlled equipment acquire the management request loaded on the business TCP connection from the business TCP connection and load the management on the local connection to send the management business units of the controlled equipment. Compared with the prior art, the equipment agent device and the network management device are wider in application range and not affected by whether a NAT gateway allows mapping or not.

Description

technical field [0001] The present invention relates to network management technology, in particular to a technical solution for a general network management service crossing NAT. Background technique [0002] With the development of information technology, there are more and more computer terminals, servers and various network devices including switches and routers in enterprises. Different branches of an enterprise are distributed in different locations, and network devices are also distributed in different regions. In order to achieve unified management, the management station may need to manage different devices across the wide area network. [0003] In the environment of IPV4, the shortage of IP address resources has been a long-standing problem. And for the security of network devices, many network devices use private IP addresses. In this case, the managed network device needs to be within the gateway with NAT function, and the IP address of the network device is i...

Problems solved by technology

The above two solutions have their own characteristics, but they also have their limitations for some application scenarios. For example, when the gateway does not allow NAT mapping to be enabled, neither solution 1 nor solution 2 can do anything.
