Description

Method, device and system for acquiring remote object external network IP address

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for acquiring an external network IP address of a remote object.

Background

NAT (Network Address Translation) is set on the boundary between the external Network and the internal Network, and its function is to map the IP addresses visible to the external Network with the IP addresses used by the internal Network, so as to ensure that multiple ranges of IP addresses can be reused in the internal Network, while these internal Network addresses are not used for the external Network. The data packet containing the IP address of the external network from the external network reaches the NAT firstly, and the NAT modifies the data packet by using a preset rule and then forwards the data packet to the receiving point of the internal network. The data packets flowing from the intranet also need to undergo a similar conversion process.

When network planning is carried out, because the network management server needs to directly communicate with the network element, the network management server and the network element are required to be in the same visible network, and the security of the network where the network element is located is very important, so that the network where the network management client is located is not allowed to be directly accessed, and NAT needs to be arranged at the boundary of the network where the network management server and the network management client are located for isolation.

With the increasing of network management scale, a network management server needs to adopt distributed deployment, that is, a plurality of network elements are arranged on the side of the network management server, after a network management client logs in a node of the network management server, a second node of the network management server needs to be accessed for processing services, at this time, the network management server can only obtain an intranet IP address of the second node, but due to the existence of NAT, the network management client cannot log in the second node by using the intranet IP address, so that the network management client cannot access the second node to complete the services. The solution in the prior art is to access a node of a network management server in a domain name manner, specifically: the mapping relation between the IP address and the domain name of the node is set in the configuration files of the network management client and the network management server, so that when the network management client accesses the node in the network management server, the domain name of the node to be accessed is converted to obtain the corresponding external network IP address, and the external network IP address is used for directly accessing the node.

In the process of implementing the above access network element, the inventor finds that at least the following problems exist in the prior art: the solution in the prior art is applied to a telecommunication gateway system, and when a mapping relation between a host name and an IP address is configured, a mapping relation between an external network IP address and the host name of all nodes of a network management client needs to be configured on a network management client side, and a mapping relation between an internal network IP address and the host name of all nodes of a network management service side is configured on a network management service side, so that the configuration of the mapping relation is complex, and the networking cost is increased; when the network networking plan changes, the content of the configuration file of each network management client node and each network management server node needs to be adjusted, so that the network maintainability is reduced, and the maintenance cost is increased.
