【摘要】 随着大型公司的进一步发展壮大,原有的通信方式已经不能满足快速发展需要,并且公司企业在网络质量、速度及安全方面提出了更高的要求。MPLS VPN技术具备宽速度高、接入方式灵活和带宽复用技术等特点,主要用于对网络带宽有较高需求视频监控线路或对网络的安全要求较低的中小企业网络需求上。MSTP技术则具备其传统数字专线的物理隔离、环路保护等高安全性的特征,在政府、金融、军事驻地等用户中使用较多。两种网络相互结合组建新一类的专线网络,可以为现在大型企业的跨省、市甚至全国性的高速率带宽和高安全性网络提供解决方案。首先,本文从MPLS VPN和MSTP两种网络技术的原理着手,MPLS VPN的研究包括MPLS VPN原理、MPLS的标签报文的转发、MPLS VPN的体系架构、MPLS VPN的路由选择等。MSTP的技术介绍中包括MSTP概述、MSTP技术发展、MSTP的技术优势和MSTP的关键技术等。其次,进行两种网络进行混合专网网络的组建,阐述了两种网络组建网络功能需求、网络组建规划,在此基础上,对混合专网建设进行了设备选型和网络数据规划。最后,按照混合专网的网络功能需求和网络建设规划,对所组建的网络中的各个网络设备进行数据规划并按照数据规划对设备进行配置。按照网络设计,对于该网络能够实现的功能进行了测试,可以完全达到之前的设计要求。整个网络组建过程中,可以验证MPLS VPN和MSTP两种网络是能够相互结合进行混合专网的建设的。以MPLS VPN网络作为整个网络中跨域传输主干部分,MSTP作为混合专网的接入部分这种方式进行网络组建,可以减少原来单一使用MSTP组建网络的资费,并且也能够提供高速率、大带宽的接入,也可以减少单一使用MPLS VPN组建网络的安全风险。更多还原

【Abstract】 With the further development of a large company, the original communication mode has already can’t meet the needs of the rapid development, and companies in the network quality, speed and security put forward higher requirements. MPLS VPN technology with high speed, flexible access and wide bandwidth multiplexing technology etc, is mainly used to have higher demand on network bandwidth video monitoring lines or lower to the network security requirements of small and medium-sized enterprise network requirements. MSTP technology with its traditional digital line protection of physical isolation, loop high security features, such as government, finance, military garrison the use of more users. Two network together to form a new kind of special line network, can provide large enterprises across the province, city or even nationwide now the high rate of bandwidth and high security network to provide solutions.This article from the principle of MPLS VPN and MSTP network technology, MPLS VPN research including the principle of MPLS VPN, MPLS label packet forwarding, MPLS VPN architectures, MPLS VPN routing, etc. MSTP technology introduction includes summary of MSTP, MSTP technology development, MSTP technology advantages and key technology of MSTP, etc. In the full study of two kinds of network analysis, on the basis of the two kinds of network, proposed the feasibility conclusion mixed together to form a private network for two kinds of networks after mixed private network construction has carried on the detailed argumentation, structured for two kinds of mixed to form a network message transfer and forward process after done. In the study found that both the network can provide good network support for the etheric business, and found that two types of network in some ways the supported business have similarities, theoretically verified the feasibility of the two together to form a network.After completion of the theoretical research, combining with the theory of knowledge, in the China PICC shandong province branch cross domain network forming process, using the hybrid network. In the process of the network sets up, the research on the network needs of customers first, on the basis of summarizing the research results, according to the mixed network model for the client network planning believe the network topology, in accordance with the requirements of the network topology and network design to achieve the required, selection of equipment. Determine the device type, each of the network devices in the network formed by planning data and configuration of equipment in accordance with the data plan. According to the network design, for the network can realize the function of the tested, before can completely reach the design requirements.In the process of the entire network to form, both can verify MPLS VPN and MSTP network can be combined with each other in private network construction. In MPLS VPN network as the cross-domain throughout the network transmission trunk, MSTP as a mixture of private network access for network to form a part this way, can reduce the original single use MSTP to form a network charges, and can also provide access to high speed, large bandwidth, can also reduce the single use of MPLS VPN network security risk.更多还原
