Abstract
The invention discloses a method, a device and a system for acquiring an outer network internet protocol (IP) address of a remote object and relates to the technical field of communication. By the invention, the outer network IP address of the remote object which is accessed can be acquired by a client in a random networking mode. The method comprises the following steps of: acquiring a first outer network IP address which is used for logging in a server by the client and an inner network IP address of a remote object to be accessed; according to the first outer network IP address and the inner network IP address of the remote object to be accessed, generating a second outer network IP address which corresponds to the remote object to be accessed; or, receiving the second outer network IP address which corresponds to the remote object to be accessed and is sent by the server. The embodiment of the invention is mainly applicable to the process of acquiring the outer network IP address of the remote object which is accessed by the client.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of acquisition methods, Apparatus and system of remote object outer net IP address.
Background technology
NAT (Network Address Translation, network address translation) be arranged on the border of outer net and Intranet, its function is mapped in visible for outer net IP address and Intranet IP address used, to ensure the IP address can reusing multiple scope in Intranet, and these internal address are not used in outer net.The packet containing outer net IP address come from outer net first arrives NAT, and NAT uses the rule preset to carry out Update Table bag, and then is transmitted to Intranet acceptance point.The packet flowed out from Intranet also needs through similar conversion process.
When carrying out the network planning, because network management service is wanted directly and net element communication, so require that network management service and network element are in same visible network, and the fail safe of the network at network element place is extremely important, therefore do not allow NM client place network directly to access, thus need that NAT is set at the boundary of network management service and NM client place network and isolate.
Along with the continuous increase of network management scale, network management service needs to adopt distributed deployment, namely network manager service side is provided with multiple network element, NM client is after the node logging in network management service, second node of accessing this network management service can be needed because of process business, now network management service can only obtain the IP address of internal network of this second node, but due to the existence of NAT, NM client can not use this IP address of internal network to log on second node, make NM client can not access second node finishing service.Solution of the prior art is the node being visited network management service by the mode of domain name, be specially: the mapping relations between the IP address of node and domain name are set in NM client and network management service configuration file, make NM client when accessing the node in network management service, obtain corresponding outer net IP address by carrying out conversion process to the domain name of the node that will access, and use this outer net IP address directly to access this node.
State in the process of access network element in realization, inventor finds that in prior art, at least there are the following problems: above-mentioned solution of the prior art is applied in telecommunications gateway system, and when the mapping relations of configure host name and IP address, need to configure the outer net IP address of all nodes of NM client and the mapping relations of host name in NM client side, in the IP address of internal network of all nodes of network manager service side configuration network management service and the mapping relations of host name, mapping relations are configured complicated, improve networking cost; And when network organizing planning changes, need the content of the configuration file adjusting each NM client node and each network manager service end node, network operation is reduced, improves maintenance cost.
