Application-oriented name registration system and its service method under multi-layer NAT environment

Abstract

The invention provides an application-oriented name registration system in multi-layer NAT environment, comprising a system terminal device and a registration service unit including a top-layer registration service unit accessing public network and a basic registration service unit accessing private network; the registration service unit is used for receiving the logging request massage of the system terminal device, and recording the user logging information of the system terminal device, the user logging information at least includes a user ID, a user entry point of the user's system terminal device in the network accessed by the registration service unit, and a access point of the user's system terminal device in the network accessed by the registration service unit. The invention can locate in multi-layer NAT environment by identification, and make the service in private network visible to external network and unrelated to specific application. The invention also provides a system and a method of more reasonable access approach for external network node.

Description

technical field [0001] The invention belongs to the technical field of computer networks, in particular to an application-oriented name registration method under a NAT environment. Background technique [0002] 1. Service access problems caused by the widespread deployment of NAT [0003] As we all know, due to the limited IP address space and uneven distribution, there is a serious shortage of network addresses. From the perspective of practical application and deployment, NAT (Network Address Translator) technology is an important method to solve the problem of insufficient IP addresses for netizens to access the Internet. With the increase of personal information devices, the popularization of network access devices, and the development of network technology, more and more companies, groups and families hope to organize these devices together in a network and connect them to the Internet. In consideration of security, how to hide high-security nodes on the network is a p...

AI Technical Summary

Problems solved by technology

It is not difficult to find that these implementation solutions are closely related to specific applications, and are embedded in the application as a functional module, and for the host node under the same root multi-layer NAT as the service, it must also be served through the public network Node relay provides services, which is obviously unreasonable
