【摘要】：MPLS_VPN(Multiprotocol Label Switching Virtual Private Network,多協(xié)議標(biāo)簽交換虛擬私有網(wǎng)絡(luò))是一種新穎實(shí)用的網(wǎng)絡(luò)技術(shù)。VPLS(Virtual Private LAN Service,虛擬專用局域網(wǎng)服務(wù))是MPLS_VPN的二層實(shí)現(xiàn)。MPLS_VPN能夠像傳統(tǒng)VPN那樣將不同地域的各用戶站點(diǎn)組成一個(gè)邏輯上的虛擬專用網(wǎng)。通過(guò)運(yùn)營(yíng)商網(wǎng)絡(luò)進(jìn)行隧道連接,MPLS_VPN能為接入該網(wǎng)絡(luò)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(shè)費(fèi)用、較簡(jiǎn)便的維護(hù)方式以及更好的安全性。本文主要在以下三方面進(jìn)行研究。1.通過(guò)對(duì)MPLS_VPN相關(guān)協(xié)議的充分研究并分析用戶的實(shí)際需求,確定目標(biāo)設(shè)備的功能。找到在MPLS_VPN網(wǎng)絡(luò)條件下接入設(shè)備的基本硬件需求。選取合適的硬件設(shè)備,結(jié)合EDA設(shè)計(jì)技術(shù),設(shè)計(jì)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_(tái),為上層應(yīng)用提供基礎(chǔ)。2.研究比較國(guó)內(nèi)外各種MPLS_VPN,尤其是VPLS網(wǎng)絡(luò)的接入技術(shù),參考用戶網(wǎng)絡(luò)的實(shí)際情況和需求,研究了VPLS網(wǎng)絡(luò)接入的特點(diǎn)和數(shù)據(jù)格式,據(jù)此制定了具體的實(shí)現(xiàn)方案,設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)基于MAC in MAC技術(shù),同時(shí)擁有用戶隔離、快速接入、簡(jiǎn)易配置、優(yōu)化網(wǎng)絡(luò)等優(yōu)秀特性的接入平臺(tái)。3.利用一個(gè)小型實(shí)用網(wǎng)絡(luò)搭建了測(cè)試環(huán)境,并采取一系列試驗(yàn)證明了該平臺(tái)的可行性和有效性。當(dāng)前該接入器設(shè)備已正式應(yīng)用在目標(biāo)用戶網(wǎng)絡(luò)中,獲得很好的使用效果。最后討論對(duì)該應(yīng)用的優(yōu)化方法和實(shí)現(xiàn)其他應(yīng)用的途徑。在測(cè)試環(huán)境中實(shí)現(xiàn)了大量用戶靜態(tài)路由配置,實(shí)現(xiàn)了用戶自由入網(wǎng)功能,減少了公網(wǎng)接入設(shè)備90%以上的地址存儲(chǔ)量,減少了90%以上的配置時(shí)間和70%以上的線路鋪設(shè)費(fèi)用,取得了極好的實(shí)用效果�；诒菊撐奶岢龅姆桨冈O(shè)計(jì)接入適配設(shè)備,可以有效減少網(wǎng)絡(luò)搭建、管理過(guò)程中的配置操作,降低對(duì)維護(hù)管理時(shí)的技術(shù)難度,從而有效減少網(wǎng)絡(luò)的開通成本和運(yùn)維成本。在為用戶提供高效連接的同時(shí)還保護(hù)用戶現(xiàn)有設(shè)備價(jià)值。該方案的硬件平臺(tái)具有極大的拓展性,可以在該平臺(tái)上實(shí)現(xiàn)多種MPLS_VPN技術(shù)的應(yīng)用。
[Abstract]:MPLS_VPN (Multiprotocol Label Switching Virtual Private Network, multi-protocol label switching virtual private network) is a novel and practical network technology. VPLs (Virtual Private LAN Service, Virtual Private Local area Network (VPN) is the second layer implementation of MPLS_VPN. VPN can form a logical virtual private network (VPN) from user sites in different regions like traditional VPN. Through the tunnel connection through the operator network, MPLS_VPN can provide the link effect similar to the local area network for the users who access the network. In addition, it has some better features than traditional VPN: lower data overhead, lower opening cost, easier maintenance and better security.

Through the full study of MPLS_VPN related protocols and the analysis of the actual needs of users, the function of the target equipment is determined. Find out the basic hardware requirements of the access device under the condition of MPLS_VPN network. Select the appropriate hardware equipment, combined with EDA design technology, design an access hardware platform that not only meets the needs of users, but also has a certain expansion potential, which provides the basis for the upper application. 2. This paper studies and compares the access technology of various MPLS_VPN, especially VPLS network at home and abroad, refers to the actual situation and requirements of user network, studies the characteristics and data format of VPLS network access, and formulates the concrete implementation scheme. An access platform based on MAC in MAC technology is designed and implemented, which has excellent characteristics such as user isolation, fast access, simple configuration, optimized network and so on. A small practical network is used to build the test environment, and a series of experiments are carried out to prove the feasibility and effectiveness of the platform. At present, the access device has been officially applied in the target user network, and good results have been obtained. Finally, the optimization method of the application and the ways to realize other applications are discussed. A large number of user static routing configurations are realized in the test environment, the function of free access to the network is realized, the address storage capacity of the public network access equipment is reduced by more than 90%, the configuration time is reduced by more than 90%, and the line laying cost is reduced by more than 70%. Excellent practical results have been obtained. Based on the scheme proposed in this paper, the design of access adaptation equipment can effectively reduce the configuration operation in the process of network construction and management, and reduce the technical difficulty of maintenance management, so as to effectively reduce the opening cost and operation and maintenance cost of the network. It not only provides efficient connection to users, but also protects the value of existing devices. The hardware platform of this scheme has great expansibility, and it can realize the application of many kinds of MPLS_VPN technology on this platform.
