摘要

随着网络的逐步普及，中小型企业的网络建设是企业向信息化发展的必然选择，企业网络系统则是一个非常庞大而复杂的系统，它能实现企业的现代化管理，实现总部与分部、不同业务之间的通信。因此，设计一个安全、高效的企业网络已成为当务之急。

论文主要以M公司为例，根据M公司的实际需求，通过掌握相关网络知识，设计一个能够实现企业网内部的通信，其中包括总部与分部、不同业务之间的通信。而对于M公司的总部与分部之间，由于距离相隔较远，要向运营商租用E1专线来实现互通。论文主要是通过分析企业网的背景、目的与意义，然后结合企业网的背景以及未来发展趋势，说明设计一个企业网的迫切性。并以M公司为例，根据公司结构设计具体的拓扑图，再根据拓扑图进行分析，进行相应的网络仿真配置。最终，实现M公司总部与分部之间的通信，并通过VLAN、OSPF、冗余备份协议等网络技术，不仅能够实现业务隔离，对后期的维护也有很大的帮助。

关键词：企业网络；拓扑图；仿真；业务隔离

ABSTRACT

As the gradual popularity of network, the construction

of the small and medium-sized enterprise's network is the inevitable choice of enterprises to the development of informationizing and enterprise network system is a very large and complex system which is able to realize the modernization of enterprise management, realize the communication between , and the communication between different business Therefore, it is extremely urgent to design a safe as well as example. I will design one communication network that can achieve enterprise internal communication based on the actual requirements of M company and my familiarity to the network knowledge. This communication network includes the , the communication between different business. As for the for the distance between them is too far. The thesis mainly emphasizes the urgency of designing enterprise network through the analysis of the background, purpose and significance of enterprise network, and combining with the background of enterprise network, and the future development trend. Besides, taking a case study of M company, in accordance with company’s configuration to design the concrete topological graph and analyze the topology, then carry on the corresponding network

simulation configuration In the end, communication between the realize the business segregation, but also do grate favor to the later maintenance.

Keywords:Enterprise Network；Topological graph；Simulation；Business segregation
