Dr．COM认证环境下Internet接入共享与仿真

为了满足企业内、外网之间灵活访问的需求，设计了一个改进的Internet接入共享方案，基于路由和远程访问服务和网络地址转换技术，成功实现了Dr．COM宽带认证环境下主机和移动终端的网络接入共享，并在VMware虚拟机上仿真某企业网络．改进后的方案，无需购置专用硬件路由器，具有成本低、软硬件可扩充性强、组网灵活等优点，尤其适用于中小型企业，并为工程技术人员研究In—ternet接入提供了有益参考．

Internet access share and the simulation under the Dr. COM authentication environment

In order to meet the flexible access requirements between internal and external enterprise net- work, the improved Internet connection share scheme based on RRAS and NAT was designed. The simula- tion of the company network based on VMware virtual machine was carried out, and Internet access share of host and mobile terminal under the Dr. COM broadband authentication environment was successfully real- ized. Compared with traditional network access scheme,without purchasing dedicated hardware routers, the improved scheme has some advantages, such as the lower cost, the strong scalability of hardware and soft- ware,the flexible networking, etc, which was especially suitable for small and medium enterprises. This scheme provided the beneficial reference about studying Internet access for engineering and technical per- sonnel.
