摘要：随着信息技术的迅猛发展，企业如今对信息化提出了更严峻的要求，各中小企业信息技术发展的程度层次不齐，这很大程度上影响了了中小企业的发展。大多数人总觉得设备性能的好坏是影响网络性能的主要因素，认为只要设备性能足够，网络就没有问题；其实这是很大的误解。园区网络的性能优劣通常是由很多因素决定的，比如设备、冗余、优化设计方案等等。在对网络进行设计的时候，需要考虑很多，要清楚的了解环境需求，想到可能出现的问题，应用可实现的技术来确保日后网络的正常工作；确保网络的高可用、安全、负载等基本保障，按照这样的方向设计网络，可以搭建出相对安全、高效的、冗余同时又是经济的网络。本文通过一个网络案例，来演示冗余、负载、高可用、安全等操作；针对使用到的技术做详细介绍、列出实施步骤。可以通过本文来掌握相关技术，并熟悉平时运文的内容和重要。29437

Campus network design and implementation
Abstract：With the rapid development of information technology, enterprises now to the information proposed more severe, and the degree of the small and medium-sized enterprise information technology development level not neat, which greatly influenced the development of small and medium-sized enterprises.
Most people feel equipment performance is good or bad is the main factors influencing the performance of the network, that as long as enough equipment performance, the network is not a problem; in fact, this is a big misunderstanding. Performance of the campus network is usually determined by many factors, such as equipment, redundancy, optimization design and so on. When design and the network and need to consider many, to clear understanding of the needs of environment, think of possible problems and applications can implement the technology to ensure the normal work of the future network. Ensure that the network high availability, security and load the basic guarantee, in accordance with this design direction of the network, to build a relatively safe and efficient, redundancy and network economy.
Through a network of case, to demonstrate the redundancy, load, high availability and security operation; according to the technology used to do detailed, list implementation steps.  Can master this technology, and familiar with the operation and maintenance of the usual and important content.
Keywords: small and medium-sized enterprise campus network, load, high availability, security, monitoring, case
