Description
技术领域technical field
本发明涉及网络及数据通讯技术领域，具体为一种基于IPv6解决信息孤岛问题的互联互通装置。The invention relates to the technical field of network and data communication, in particular to an interconnection and intercommunication device for solving the problem of isolated information islands based on IPv6.
背景技术Background technique
“信息孤岛”是指多个不同类型而又相互独立的，有信息交换的需要，但是又相互封闭，无法进行正常沟通的信息系统。在信息化建设过程中，由于受到多方面因素的综合作用，各行业单位在各地分支机构建造了大量的信息系统，随着技术和管理的发展，越来越多的应用信息需要信息共享、信息互通。所以“信息孤岛”逐渐成为各产业信息化发展过程中难以跨越的障碍，如何解决信息孤岛问题成为一个新的难题。"Information islands" refer to multiple different types of information systems that are independent of each other, have the need for information exchange, but are closed to each other and cannot communicate normally. In the process of informatization construction, due to the combined effects of various factors, various industry units have built a large number of information systems in various branches. With the development of technology and management, more and more application information requires information sharing, information intercommunication. Therefore, "information islands" have gradually become an insurmountable obstacle in the process of informatization development in various industries, and how to solve the problem of information islands has become a new problem.
以某单位举例，在各地均有分支机构，各分支机构建设了自有信息系统用于单位内部各种资源的管理，且各地分支机构内部网络拓扑、IP地址及信息系统均由各分支机构自行规划，可以认为各分支机构内部网络及信息系统是一个个独立的信息孤岛，且由于其内部大都使用IPv4私网地址进行地址规划，很大机率各分支机构存在IPv4私网地址重复的现象。现要求各分支机构实现网络及信息系统互联互通，以实现数据共享。传统的解决方案是通过专用VPN打通各地分支机构的内部网络实现网络的互通，但当各分支机构出现IPv4私网地址重复时就没办法解决网络互联互通的问题了。为各分支机构数据共享带来很大困难。Taking a certain unit as an example, there are branches all over the country, and each branch has built its own information system for the management of various resources within the unit, and the internal network topology, IP address and information system of each branch are all managed by each branch. Planning, it can be considered that the internal network and information system of each branch is an independent information island, and because most of them use IPv4 private network addresses for address planning, there is a high probability that there will be duplication of IPv4 private network addresses in each branch. All branches are now required to realize the interconnection and intercommunication of the network and information systems to realize data sharing. The traditional solution is to open up the internal network of branches in various places through a dedicated VPN to realize network intercommunication, but when there are duplicate IPv4 private network addresses in each branch, there is no way to solve the problem of network interconnection. It brings great difficulties to the data sharing of various branches.
