摘要

随着Internet在我们生活中的应用发展，企业网的建设也已渐渐成为企业向现代化、信息化发展的必经之路。企业网络的建设是一项庞大而复杂的工程，它不仅为企业提供现代化办公和信息资源共享的平台，而且可以同时提供各种各样的应用服务。在企业网的建设中，既要考虑到当前企业的实际需求，也要考虑到企业网络的扩展性和向后的兼容性，方便企业日后对网络的升级。整个网络设计过程主要包括：对企业进行需求分析、设计网络拓扑结构、选择组网技术、网络设备的选型、服务器的配置、综合布线方案和实施以及网络的安全性设计。

本次课题是基于对一个中等规模的企业的各种网络需求而进行规划得到的网络系统设计方案，首先对企业进行详细的需求分析，包括应用服务需求，安全需求以及扩展性需求，然后确定网络中将会提供的服务和采用的设备以及布线方式和网络拓扑的选择。论文针对对企业网络的设计与分析，使用Packet Tracer 5.3软件进行网络仿真模拟配置，并测试相关结果，从而给出网络规划设计解决方案。

Abstract

ABSTRACT

As the Internet in our life applications development, enterprise network construction has gradually become the modernization, the only way for the development of information technology. Enterprise network construction is a large and complex project, which not only provides businesses with modern office and information resources sharing platform, and can also provide a wide variety of application services. In the enterprise network construction, it is necessary to take into account the actual needs of the current business, but also taking into account the corporate network scalability and backward compatibility to facilitate business in the future to upgrade the network. Throughout the network design process include: the enterprise needs analysis, design the network topology, select the network technology, network equipment selection, server configuration, cabling design and implementation, and network security design.

The project is based on a medium-size enterprises of various network needs while planning to get a network system design, the first enterprise to conduct a detailed needs analysis, including application service requirements, security requirements, and scalability requirements, determine the network services to be provided and the use of equipment and wiring and network topology options. Thesis focuses on the design and analysis of enterprise network using Packet Tracer 5.3 simulation software for network configuration and test the relevant results, which gives network planning and design solutions.

Key words: Enterprise network, equipment selection, network technology, network topology, enterprise security
