摘要：隨著Internet已成為全社會的信息基礎(chǔ)設(shè)施，企業(yè)端應(yīng)用也大都基于IP，在Internet上構(gòu)筑應(yīng)用系統(tǒng)已成為必然趨勢，因此基于IP的VPN業(yè)務(wù)獲得了極大的增長空間。本文介紹了虛擬專用網(wǎng)的技術(shù)原理和特點(diǎn)，以及利用VPN技術(shù)構(gòu)建企業(yè)虛擬專用網(wǎng)的優(yōu)勢，提出利用公網(wǎng)的資源作為企業(yè)各級單位間傳輸信息的通道，在建設(shè)內(nèi)部網(wǎng)實(shí)現(xiàn)信息安全共享的同時(shí)降低建設(shè)和維護(hù)成本，因此具有很好的應(yīng)用前景。文章首先對VPN的技術(shù)的發(fā)展、優(yōu)點(diǎn)等進(jìn)行了分析；其次闡述了VPN的解決方案；最后，結(jié)合一個(gè)證券公司的實(shí)例說明企業(yè)VPN網(wǎng)絡(luò)的具體實(shí)現(xiàn)。

VPN technology analysis and implementation
Abstract: As the Internet has become a society-wide information infrastructure, enterprise-based applications are mostly IP, to build applications on the Internet have become an inevitable trend, so the service which based on the IP-VPN was great room for growth. This paper presents a virtual private network technology principles and characteristics, and presents the advantages that the companies use the VPN technology to build the virtual private network, by using public networks at all levels of resources as a business unit of the channel to transmit information, in building internal networks to share information security At the same time reduce the cost of construction and maintenance, so VPN has good prospects. The article first tell us something about the development of technologies VPN and other advantages of an analysis ; and secondly about the VPN solutions; Finally, it combinates a securities company examples of the specific enterprise VPN network to achieve.
Key words: VPN; VLAN; network security; tunnel
