基于VPN的企业数据共享研究与实现

Research and Realization of Enterprise Data Sharing Based on Virtual Private Network

随着现代网络通信技术的迅速发展，虚拟专用网（VPN）成为当前企业异地分公司之间的通讯和数据共享的重要途径。基于Internet等公共网络将各个异地分公司的内部网络采用虚拟专用网络中，不仅可以实现不同分公司之间的通讯与信息交流，而且可以保证数据传输的时效性和保密性。本文在分析两个异地分公司之间数据共享实际需求的基础上，研究基于VPN的企业数据共享方法，并研究基于VPN的企业数据共享实现方法，如利用数据库发布与订阅的方式实现数据同步。同时，我们分析了在利用VPN技术实现企业数据共享时需要注意的基本问题。

Since the fast development of modem network communication technology, VPN, which ensures the security and speed of transfer, has been an important way for filiales in different places to communicate and share data. Based on analysis of the actual requirement, this paper studied the sharing methods of data based on VPN, such as using the function of publishing and subscription of Microsoft SQLServer to realize data synchronization, and cycle time of synchronization should be set to a reasonable value to make sure it will work regularly. A solution of data sharing in enterprise based on VPN is proposed in this paper, and also some important issues should be paled attention.
