虛擬專用網(wǎng)技術解決了遠距離局域網(wǎng)間的資源互訪問題，使得在不同地區(qū)擁有多分
支機構的單位能夠合理、有效地利用內(nèi)部信息。隧道技術是實現(xiàn)虛擬專用網(wǎng)的關鍵技術之一，由于受到開發(fā)平臺的制約，目前關于隧道技術的研究主要集中在Linux 等源代碼開放的平臺，對Windows 平臺則很少涉及。為此，本文利用NDIS 技術，提出了Windows 平臺下虛擬專用網(wǎng)安全隧道技術的解決方案，并通過實驗對其可行性進行了驗證。驗證結果顯示，該技術方案能夠在Windows 平臺下實現(xiàn)安全隧道的主要功能，具有較廣泛的應用前景。

Abstract: VPN technology resolves the puzzle on how to visit resources of LAN in different area. It affords the technology to access information effectively in multi-branch unit. The tunnel technology is the key to implement the VPN. Because of the limit of implement environment, the implement technologies of the tunnel model emphasize on Linux which code is opened, and pay less attention to Windows. So, this paper proposes a VPN security tunnel development scheme on windows with NDIS technology and verifies its feasibility by experiments. The results show that this technology scheme can implement mainly functions of security tunnel and has more extensive application prospects.
