【正文】 中，各種各樣的用戶和業(yè)務(wù)要求相對差異的服務(wù)質(zhì)量，所以 VPN 應(yīng)當(dāng)為企業(yè)數(shù)據(jù)提供不同級別的服務(wù)質(zhì)量保證。 VPN 的特點 。 各專業(yè)畢業(yè)論文范文盡在道客巴巴下載 各專業(yè)畢業(yè)論文范文盡在道客巴巴下載 2 VPN的概述 VPN 的基本概念 VPN(虛擬專用網(wǎng)絡(luò) Virtual Private Network)指的是利用 ISP（ Inter服務(wù)提供商）和其它 NSP（網(wǎng)絡(luò)服務(wù)提供商）在公共網(wǎng)絡(luò)中建立專用的數(shù)據(jù)通信網(wǎng)絡(luò)的技術(shù)。 VPN 涉及到很多技術(shù)，包括安全隧道技術(shù)、加密解密技術(shù)、密鑰管理、用戶認(rèn)證等技術(shù)，這些技術(shù)會在本文中得到簡要的闡述，同時也會比較分析 VPN 的隧道協(xié)議及應(yīng)用模式，從而歸納出不同協(xié)議和解決方案的優(yōu)缺點以及可用范圍。隨著寬帶網(wǎng)得到普及， Inter 接入的比率提高，中小企業(yè)現(xiàn)在也可以利用 VPN 技術(shù)來擴寬專屬網(wǎng)絡(luò)。s called this, mainly because the connection of any two nodes of VPN work is not the endtoend physical link between the traditional private work , but based on the public Inter service platform, such as the Inter, ATM , Frame Relay and the logic of above, the user data works in the transmission of logical link. It covers the cross sharing work or the public work encapsulation, encryption and identity verification of the expansion of the private work links. VPN mainly adopts the color channel technology, encryption technology, key management technology and the user identity authentication technology and equipment. This paper mainly introduces the related technologies of VPN and the agreement parative it takes Shijiazhuang YongJia housing panies for a example to introduce the cases of specific solutions and VPN specific system configuration, and analyzes the enterprise application of many of the VPN advantages, and summarizes the enterprise application prospect VPN.
