Trends in Campus Design
In the past, network designers had only a limited number of hardware options??routers or hubs??when purchasing a technology for their campus networks. Consequently, it was rare to make a hardware design mistake. Hubs were for wiring closets, and routers were for the data-center or main telecommunications operations.
Recently, local-area networking has been revolutionized by the exploding use of LAN switching at Layer 2 (the data link layer) to increase performance and to provide more bandwidth to meet new data networking applications. LAN switches provide this performance benefit by increasing bandwidth and throughput for workgroups and local servers. Network designers are deploying LAN switches out toward the network's edge in wiring closets. These switches are usually installed to replace shared concentrator hubs and give higher-bandwidth connections to the end user.

趋势校园设计
在过去，网络设计师只有数量有限的硬件选择？ ？路由器或集线器？ ？在购买技术的校园网。因此，它是罕见的，使硬件设计错误。集线器用于布线室，和路由器的数据中心或主要电信业务。
最近，局域网络已被彻底改变了爆炸使用局域网交换机在第二层（数据链路层） ，以提高性能，并提供更多的带宽，以满足新的数据网络应用的需求。局域网交换机提供这方面的性能优势，增加带宽和吞吐量的工作组和本地服务器。网络设计者正在部署局域网交换机了对网络的优势在布线室。这些开关通常安装，以取代共享选矿厂枢纽和给予更高的带宽连接到最终用户。
例如趋势的校园设计
第3层网络需要在网络互连的交换工作组，并提供服务，其中包括安全，服务质量（ QoS ） ，以及交通管理等。路由集成这些交换网络，并提供了安全，稳定和控制所需的功能和可扩展的网络。
传统上，第二层交换提供了局域网交换机和第三层网络已经提供了路由器。越来越多，这两个网络的功能正被纳入共同平台。多层交换机，提供第2层和3个功能，例如，现在出现在市场。
随着这种技术的第三层交换， LAN交换和虚拟局域网（虚拟局域网） ，校园网建设正在变得更加复杂与过去相比。表1-1总结了各种网络技术的要求，建立成功的校园网。思科系统公司提供的产品解决方案，在所有这些技术。
网络设计，现在设计校园网购买单独的设备类型（例如，路由器，以太网交换机和ATM交换机） ，然后连接起来。虽然个别购买决定似乎无害，网络设计师绝不能忘记，这个单独的设备仍然工程共同组成了一个网络。
