【摘要】：網絡技術自90年代中期到現(xiàn)在，迅速發(fā)展，解決了各種經濟、生活中信息化不斷面臨的問題和挑戰(zhàn)。隨著經濟的穩(wěn)定高速發(fā)展，企業(yè)的業(yè)務也在逐漸擴張，部分企業(yè)相繼在全國范圍內設立辦事處分公司等分支機構。因此，在支持現(xiàn)有的、先進的全國集中式IT網絡架構的基礎上，如何更好的支持跨地區(qū)、跨部門業(yè)務的互聯(lián)互通，滿足全國范圍內縣域網點實現(xiàn)廣域互連、扁平化管理、迅速提升信息化水平的需求，支持企業(yè)在全國范圍內快速部署網點服務機構、迅速拓展業(yè)務，建設一個上下貫通、橫縱互聯(lián)、功能完善、高速穩(wěn)定、安全可靠、統(tǒng)一規(guī)范的網絡架構顯得尤為重要。 對于組網技術來說，VPN組網，即虛擬專用網絡被廣泛的使用。這種虛擬的專用網絡技術由于不建立物理上鏈接，主要通過技術手段虛擬一條通路實現(xiàn)網絡數(shù)據(jù)的傳輸和通信。使用VPN組網規(guī)劃的網絡具有良好的保密性以及信息傳輸不受干擾等優(yōu)點，越來越受到人們的研究和應用。由于在局域網中建立VPN鏈接時不會影響網絡內的其它計算機鏈接到公共網絡，但只能夠有一臺計算機建立鏈接，因此VPN組網的方式適合于計算機比較多的企業(yè)用戶。直聯(lián)組網也就是通過直接連接的方式構建網絡。比如各省內的三、四級機構不再鏈接到省內的一級機構或者二級機構，而是直接鏈接到網絡中心處。對于在全國范圍內迅速建立并部署網點，采用直聯(lián)組網的方式能夠既支持原有IT網絡架構，還能減少對現(xiàn)有網絡的調整和改造。 MPLS VPN是一種旨在解決現(xiàn)存網絡中存在的諸多與數(shù)據(jù)包轉發(fā)有關的問題的技術，通過MPLS VPN組網的網絡具有較好的QoS性能，滿足丟包率、時延的要求，擁有良好的冗余機制，，同時具有低投入、低使用、低維護的良好的經濟性能。因此對于在全國范圍內拓寬業(yè)務建立分支機構來說有較高的實用性和經濟效益。MPLS VPN技術作為一個重要的應用研究方向，廣泛應用到實際網絡建設中。 本文通過深入研究MPLS VPN技術、BGP路由選擇協(xié)議以及QoS技術，以中國平安機構為背景，針對該機構的網絡現(xiàn)狀以及組網需求，設計了實現(xiàn)中國平安機構直聯(lián)組網的方案，完成了系統(tǒng)的部署、參數(shù)的配置等組網實現(xiàn)工作。 通過本課題的研究使得中國平安機構的組網結構得到極大優(yōu)化，組織結構更加良好，為迅速拓展的業(yè)務導致的網絡升級提供了強有力的技術保障,實現(xiàn)了各異地分支機構對總部以及各分支機構的的各種應用系統(tǒng)及資源的安全訪問。設計的方案滿足中國平安機構的實際，達到了預先設定的建設目標。
[Abstract]:Network technology has developed rapidly from the middle of 1990s to now, which has solved the problems and challenges faced by various kinds of economy and life informatization. With the steady and rapid development of economy, the business of enterprises is expanding gradually, and some enterprises have set up offices, branches and other branches all over the country. Therefore, on the basis of supporting the existing, advanced national centralized IT network architecture, how to better support the interconnection of cross-regional and inter-departmental services, to meet the needs of nationwide county network to achieve wide-area interconnection and flattening management, To rapidly improve the level of information demand, support enterprises in the rapid deployment of network services across the country, rapidly expand business, build a top and bottom, horizontal and vertical interconnection, perfect function, high speed and stability, safety and reliability, Uniform and standardized network architecture is particularly important. For networking technology, VPN networking, that is, virtual private network is widely used. This kind of virtual private network technology realizes the transmission and communication of network data mainly by means of virtual path because it does not establish physical link. VPN network planning has the advantages of good confidentiality and non-interference of information transmission, so it has been studied and applied more and more. Since the establishment of VPN links in local area networks will not affect other computers in the network to link to the public network, but only one computer can establish links, so the way of VPN networking is suitable for enterprise users with more computers. The direct connection network is also through the direct connection way constructs the network. For example, the third and fourth level organizations in the provinces no longer link to the first or second level institutions in the province, but directly link to the network center. For the rapid establishment and deployment of network in the whole country, the direct network can not only support the original IT network architecture, but also reduce the adjustment and transformation of the existing network. MPLS VPN is a technology aimed at solving many problems related to packet forwarding in existing networks. The network with MPLS VPN has better QoS performance, meets the requirements of packet loss rate and delay, and has a good redundancy mechanism. At the same time with low input, low use, low maintenance of good economic performance. Therefore, as an important research direction, MPLS VPN technology is widely used in practical network construction. In this paper, the MPLS VPN routing protocol and QoS technology are studied in depth. Based on the background of China Ping an Organization, according to the current network situation and the network requirements of the organization, a scheme to realize the direct networking of China Ping an Organization is designed. Completed the system deployment, parameter configuration and other network implementation work. Through the research of this topic, the network structure of China Ping an Organization is greatly optimized, and the organization structure is better, which provides a strong technical guarantee for the network upgrade caused by the rapidly expanding business. The secure access to various application systems and resources of different branches is realized. The designed scheme meets the reality of China's safety organization and achieves the predefined construction target.
