【摘要】：MPLS_VPN(Multiprotocol Label Switching Virtual Private Network,多協(xié)議標簽交換虛擬私有網(wǎng)絡)是一種新穎實用的網(wǎng)絡技術。VPLS(Virtual Private LAN Service,虛擬專用局域網(wǎng)服務)是MPLS_VPN的二層實現(xiàn)。MPLS_VPN能夠像傳統(tǒng)VPN那樣將不同地域的各用戶站點組成一個邏輯上的虛擬專用網(wǎng)。通過運營商網(wǎng)絡進行隧道連接,MPLS_VPN能為接入該網(wǎng)絡的用戶提供類似局域網(wǎng)的鏈接效果。此外它還擁有一些較傳統(tǒng)VPN更好的特性:較低的數(shù)據(jù)開銷、較低的開設費用、較簡便的維護方式以及更好的安全性。本文主要在以下三方面進行研究。1.通過對MPLS_VPN相關協(xié)議的充分研究并分析用戶的實際需求,確定目標設備的功能。找到在MPLS_VPN網(wǎng)絡條件下接入設備的基本硬件需求。選取合適的硬件設備,結合EDA設計技術,設計出一種即滿足用戶需求又具有一定拓展?jié)摿Φ慕尤胗布脚_,為上層應用提供基礎。2.研究比較國內(nèi)外各種MPLS_VPN,尤其是VPLS網(wǎng)絡的接入技術,參考用戶網(wǎng)絡的實際情況和需求,研究了VPLS網(wǎng)絡接入的特點和數(shù)據(jù)格式,據(jù)此制定了具體的實現(xiàn)方案,設計并實現(xiàn)了一個基于MAC in MAC技術,同時擁有用戶隔離、快速接入、簡易配置、優(yōu)化網(wǎng)絡等優(yōu)秀特性的接入平臺。3.利用一個小型實用網(wǎng)絡搭建了測試環(huán)境,并采取一系列試驗證明了該平臺的可行性和有效性。當前該接入器設備已正式應用在目標用戶網(wǎng)絡中,獲得很好的使用效果。最后討論對該應用的優(yōu)化方法和實現(xiàn)其他應用的途徑。在測試環(huán)境中實現(xiàn)了大量用戶靜態(tài)路由配置,實現(xiàn)了用戶自由入網(wǎng)功能,減少了公網(wǎng)接入設備90%以上的地址存儲量,減少了90%以上的配置時間和70%以上的線路鋪設費用,取得了極好的實用效果�；诒菊撐奶岢龅姆桨冈O計接入適配設備,可以有效減少網(wǎng)絡搭建、管理過程中的配置操作,降低對維護管理時的技術難度,從而有效減少網(wǎng)絡的開通成本和運維成本。在為用戶提供高效連接的同時還保護用戶現(xiàn)有設備價值。該方案的硬件平臺具有極大的拓展性,可以在該平臺上實現(xiàn)多種MPLS_VPN技術的應用。
