大型企业环境下的计算机网络的集成

The Integration of Large-Scale Enterprise Networking Environment

大型企业网络的互联涉及到总体设计和异质网络的互联．其中重要的是如何选择网络协议和协议族来实现互通性．由于ＴＣＰ／ＩＰ协议具有良好的包容性，所以它成为网络互联中最常用的协议族，建立在网络协议之上的是操作系统和应用．目前在网络数据库和基于网络的应用中通常采用客户机／服务器模式．操作系统的互通和互操作也是一个需要考虑的问题；复杂的网络还需要高级的网络管理系统来保证正常的运行．智能网络管理也是金桥网络工程中心研究方向之一．

The integration of large-scale enterprise network involves many different aspects of technologies. First of all, the overall design is the basis of the whole process of system integration, which will decide the efficiency, quality, performance and upgrade ability of a network. The interconnection of heterogeneous networks is another practical problem, including both hardware and software considerations. The most important issue of this section is how to select protocols or protocol suites to achieve intercommunication. TCP/IP is mostly used as chief protocols in this area because this protocol suite can communicate other kinds of systems very well. Applications are built upward protocols, which face directly to the user's demands. Client/Server mode is widely used currently in remote database query, event processing and other kind of applications. Complex networks also need advanced network management system to ensure proper operation. Intelligent network management is one of the research focuses of the Golden Bridge Network Engineering Center and is introduced in brief in this paper.
