【摘要】 近年来,越来越多的企业、机关事业单位纷纷建造自己的内部办公网络。经常会出现地理位置较为分散、连接起来比较麻烦的情况。如何在地理位置分散的办公网点方便地建造局域网、有效地利用现有的网络资源、方便快捷地管理一个日益庞大的局域网络,这是摆在每一个网络管理员面前很现实的问题。利用传统的DDN、帧中继专线、电话拨号等方式已经不能适应通信发展的需要。本论文探讨了利用ADSL组建基于VLAN远程办公网络的组网方案的可行性和关键技术。主要贡献为: 1.研究了VPN网络的技术特点,并对VPN技术进行分析。讨论了VPN网络的分类标准; 2.通过分析802.1Q协议的基本特点,以及VLAN的优点,讨论了VLAN的实现技术 3.对宽带城域的技术特点,宽带设备以及ADSL的技术特点,结合山东网通宽带城域网的网络结构进行了研究; 4.分析远程办公网的特点,结合宽带城域网的技术以及VLAN技术的特点,设计了利用ADSL技术组建基于VLAN的远程办公网络的组网方案。并通过章丘医保网的实际案理作了实现和测试研究。更多还原

【Abstract】 In recent years, more and more corporations and departments have built their intra- communicating network. However, as the terminals spread around separately in location, it’s inconvenient to link them together. To a network administrator, the problems are how to built a LAN in dispersive location conveniently, how to make full use of the network resources, how to manage the more and more enormous local network. It can’t meet the needs of communication to utilize traditional network such as DDN, frame relay and dial-up network. In this paper, we will introduce a scheme of VLAN based on ADSL. The following respects are discussed:1. VPN technology and its characteristic are introduced, and the classification standard of VPN is also introduced;2. we will talk about the characteristic of 802.1Q protocol, the virtue of VLAN and its construction;3. the characteristic of wide-band MAN, wide-band equipment and ADSL are discussed combined with MAN of Shandong CNC;4. with the technology characteristics of wide-band MAN and VLAN, we will discuss the properties of telecommuting network, and the telecommuting network scheme based on VLAN with ADSL technology. Also, the case of Medical Treatment and Health Care Network of Zhangqiu is discussed.更多还原
