利用局域网构建安全的信息化高校实验室

摘要

探讨了如何利用局城网技术开发信息资源,促进信息交流和知识共享,提高资源设备利用率和教学科研效率,改变实验室内部信息孤岛的状况,构建一个安全的信息化实验室.具体讨论了局域网的树形拓扑结构设计、网络和信息安全设计、IP地址规划以及部署在其上的服务和功能.该局域网方案实现了实验室内的软硬件资源的共享、点对点通讯、仪器设备远程化操作、分布式实验数据库系统、分布式存储和计算、团队协作式开发、信息化管理、Web服务、Email和传真服务等一系列功能,提高了实验室信息化水平,取得了良好的应用效果.%This paper discusses how to use local area network (LAN) technology to develop information resources, to promote information exchange and knowledge sharing, to improve resource utilization and efficiency of teaching and research, to change the situation of inside information island and construct a safe information college laboratory. Design of tree topology,network and information security, IP address planning, and deployment of services and functions on it are discussed in detail.The laboratory LAN designed implements functions of laboratory resource sharing, peer to peer communications,instrumentation equipment, remote-based operations, distributed databases experiment, distributed storage and computing,collaborative team development, information management, web services, Email and fax services and secrecy services needs.This LAN program improves the information level of laboratory and obtains good application effect.
