【摘要】：隨著近年來Internet網(wǎng)絡(luò)的不斷發(fā)展,隨時(shí)隨地移動(dòng)辦公成為越來越多用戶的需求。VPDN英文全稱“Virtual Private Dial-up Networks",網(wǎng)絡(luò)組建中用戶主點(diǎn)采用專線方式接入,遠(yuǎn)端用戶通過撥號方式接入,是基于運(yùn)營商無線網(wǎng)絡(luò)全覆蓋建構(gòu)的虛擬專用撥號網(wǎng)絡(luò)�；贛PLS VPN的VPDN組網(wǎng)的建設(shè)要求具備AAA認(rèn)證和授權(quán)機(jī)制,融合了MPLS VPN和VPDN技術(shù)的優(yōu)點(diǎn),具有系統(tǒng)靈活且安全可靠、操作簡便、管理便捷等特點(diǎn)。本文首先對基于MPLS VPN的VPDN網(wǎng)絡(luò)關(guān)鍵技術(shù)進(jìn)行了綜述,包括MPLSVPN的標(biāo)簽轉(zhuǎn)發(fā)、LNS復(fù)用、加密技術(shù)、QoS技術(shù)和VPDN的核心技術(shù)。其中MPLS-VPN的LNS復(fù)用思想解決了不同種類LNS路由配置的兼容復(fù)雜性,將系統(tǒng)的復(fù)雜性集中在ISP一端,ISP中LAC服務(wù)器只需與1-2臺LNS設(shè)備互通,用戶只需接入MPLS VPN網(wǎng)絡(luò)即可完成網(wǎng)絡(luò)部署,新增用戶時(shí),不需要重新進(jìn)行LAC和LNS之間的互通測試。隧道技術(shù)建立在用戶網(wǎng)關(guān)和接入服務(wù)器之間,負(fù)責(zé)把用戶內(nèi)網(wǎng)和公網(wǎng)的數(shù)據(jù)流量分開,遠(yuǎn)程接入用戶可通過隧道登錄到企業(yè)內(nèi)網(wǎng)中�；贛PLS VPN的VPDN網(wǎng)絡(luò)技術(shù)融合了MPLS VPN和傳統(tǒng)VPDN的網(wǎng)絡(luò)優(yōu)點(diǎn),既降低了企業(yè)投資和維護(hù)成本,并兼有MPLS VPN組網(wǎng)的安全靈活性。本文其次介紹了農(nóng)村信用社VPDN網(wǎng)絡(luò)的組建背景、基于MPLS VPN的VPDN網(wǎng)絡(luò)體系的選用,并重點(diǎn)從MPLS VPN技術(shù)、無線網(wǎng)絡(luò)安全技術(shù)和用戶側(cè)網(wǎng)絡(luò)安全技術(shù)的角度對基于MPLS VPN的VPDN網(wǎng)絡(luò)良好安全性能進(jìn)行了分析。本文最后對基于MPLS VPN的VPDN網(wǎng)絡(luò)在農(nóng)村信用社的具體應(yīng)用進(jìn)行了研究,并從平臺的搭建、設(shè)備的采購、網(wǎng)絡(luò)設(shè)備部署和安全性能等方面進(jìn)行了詳細(xì)闡述,同時(shí)進(jìn)行了系統(tǒng)測試,確保系統(tǒng)的可用性、靈活性。本文也對農(nóng)村信用社網(wǎng)絡(luò)正常使用過程中出現(xiàn)的障礙問題進(jìn)行了分析總結(jié)�；贛PLS VPN的VPDN網(wǎng)絡(luò)在實(shí)際應(yīng)用中有重要的價(jià)值和深遠(yuǎn)的前景。
[Abstract]:With the development of Internet network in recent years, mobile office has become the demand of more and more users. VPDN is called "Virtual Private Dial-up Networks" in English. The construction of VPDN network based on MPLS VPN requires the mechanism of AAA authentication and authorization, which combines the advantages of MPLS VPN and VPDN technology, and has the advantages of flexibility, security and reliability. This paper first summarizes the key technologies of VPDN network based on MPLS VPN, including MPLSVPN label forwarding, LNs multiplexing, and so on. Among them, MPLS-VPN 's LNS reuse idea solves the compatible complexity of different kinds of LNS routing configuration, and the complexity of the system is concentrated in the ISP end of ISP. The LAC server only needs to communicate with 1-2 LNS devices. Users only need to access the MPLS VPN network to complete the network deployment. When adding new users, there is no need to re-test the interworking between LAC and LNS. The tunneling technology is built between the user gateway and the access server. It is responsible for separating the data flow of the user's intranet from the public network, and the remote access user can log in to the enterprise's intranet through the tunnel. The VPDN network technology based on MPLS VPN combines the advantages of MPLS VPN and traditional VPDN, which reduces the cost of enterprise investment and maintenance. It also has the security flexibility of MPLS VPN network. Secondly, this paper introduces the background of setting up VPDN network of rural credit cooperatives, the selection of VPDN network system based on MPLS VPN, and focuses on MPLS VPN technology. From the point of view of wireless network security technology and user-side network security technology, the good security performance of VPDN network based on MPLS VPN is analyzed. Finally, the application of VPDN network based on MPLS VPN in rural credit cooperatives is studied. And from the platform construction, equipment procurement, network equipment deployment and security performance are described in detail. At the same time, the system is tested to ensure the availability of the system. Flexibility. This paper also analyzes and summarizes the obstacles in the normal use of rural credit cooperative network. The VPDN network based on MPLS VPN has important value and far-reaching prospect in practical application.
