1、 1 摘 要 一个高效的企业办公环境对企业来说是效率和利益的保证， 图形操作系统的出现 催生了办公自动化的发展，办公自动化确实给企业的办公带来了很大的帮助。办公局 域网的出现又一次彻底的颠覆了企业的办公理念， 网络能使企业内部之间实现高速的 通信和全方位的信息共享，给企业的办公带来了极大地便利。正是由于局域网的巨大 优势，各公司企业和政府部门都纷纷建设和加强高速局域网络，利用现代化的信息技 术使公司在残酷的市场竞争中立于不败之地。 本设计中的公司是一家处于快速成长且资金雄厚的高科技技术研发和生产的中 型企业，在公司网络的设计中公司决定全部使用国际知名的思科公司的产品。在参考 大量以往成功的实例
2、后决定网络拓扑采用三层设计结构，分别是：核心层、汇聚层和 接入层，这样可以有效地分割整个企业网络的流量，保持网络的长久稳定，也便于未 来的网络扩展。 然后根据思科官方提供的资料选择各个层中的设备及模块并做相应的 配置。最后在工程实施之前在思科提供的模拟软件上模拟设计好的企业网络，以验证 网络的合理性和稳定性。 其次规划好在网络中启用的高级服务应用， 做好相应的配置， 并在 VM 虚拟机上进行模拟配置以便及时发现问题并解决。 关键词：中型企业 网络设计 交换机 服务器 虚拟机 2 Abstract An efficient business enterprise office environme
