摘要

随着互联网的飞速发展，网络的规模变化要求逐渐扩大，网络异构化趋势加剧，需要更丰富复杂的网络，对网络管理规模也有了新的要求。为此本论文设计了一个中小企业的网络工程，解决了对网络规模中的管理问题，提高了中小企业网络工程的扩展能力。

开放式最短路径优先协议（Open Shortest Path First，OSPF）是网络广泛使用的路由协议之一，它是一个基于开放标准的链路状态路由协议。OSPF是一种可扩展的路由选择协议，适用与现在的异构网络。本论文运用OSPF协议对中小企业网络工程项目进行理论论述，采用了OSPF协议、静态路由、动态路由等相关技术实现网络工程，详细地论述了OSPF协议的相关知识以及在区域上配置OSPF协议的相关步骤，并详细讨论了如何使用各个协议实现网络工程。

ABSTRACT

With the rapid development of the Internet, the requirements of network scale change gradually expand, the trend of network heterogeneity intensifies, the need for richer and more complex network, network management scale also has new requirements. Therefore, this paper designs a network project of small and medium-sized enterprises, which solves the management problem of network scale and improves the expansion ability of network project of small and medium-sized enterprises.

Open Shortest Path First (OSPF) is one of the most widely used routing protocols in network. It is a link-state routing protocol based on Open standards. OSPF is an extensible routing protocol applicable to heterogeneous networks. This paper using OSPF protocol for small and medium-sized enterprise network project theory, this paper adopted the OSPF protocol, static routing, dynamic routing implementation related technologies such as network engineering, this paper discusses on related knowledge, and in areas of OSPF protocol configuration steps of OSPF protocol, and discussed in detail how to use the protocol implementation network engineering.

Keywords: OSPF protocol, network engineering, route, extension
