某校有本科生宿舍4座，每座7层，每层10间房，每间房2个学生，。要求对学生宿舍的网络进行设计规划，设计时需满足下列要求：
在宿舍区提供一个学生服务器机房，供学生社团放置各类服务器；
在学生服务器机房，设置一个代理服务器供同学们使用
学校分配了1段C类IP地址给该学生服务器机房，IP地址为202.116.162.0/24。；
拟保证每个学生有一个上网端口；
学生机器采用私有IP地址，通过代理服务器上校外网。
设计时尽量能够减少广播风暴；
请根据以上环境和设计要求设计该网络，完成下列工作并撰写相关文档：
选择相应的网络设备（以Cisco品牌为蓝本，写出参数和数量）；
写出设计方案、画出网络拓扑结构、并阐述设计理由；
写出网络中的主要路由器及主要的交换机作的设置脚本并作简单阐述。

本书是计算机网络方面的经典畅销教科书，凝聚了两位顶尖网络专家几十年的理论研究、实践经验和大量第一手资料，自出版以来已经成为网络课程主流教材，被哈佛大学、斯坦福大学、卡内基一梅隆大学、康奈尔大学、普林斯顿大学、威斯康星大学、普度大学、得克萨斯大学、芝加哥大学等众多名校采用。
第4版秉承了前3版的特点，通过丰富的、基于实例的指导，来帮助读者理解计算机网络及其构件。全书的重点在于“为什么这样设计网络”——不仅详细叙述当今网络系统的组成，而且还阐述关键技术和协议如何在实际应用中发挥作用，从而解决具体的问题。
本书与传统网络教材最大的不同在于，不是按照OSI层次机械地介绍计算机网络，而是采用“系统方法”，将网络看成是交互式的复杂系统。每章开头都给出一些启发式的问题。引导学生或专业人员用新学到的知识来解决实际问题；同时，在每章的最后还会补充一些新的工具和资源，帮助读者巩固和加深所学知识，全面理解复杂网络及其应用的工作原理和工作方式。
When the first edition of this book was published in 1996, it was a novelty to be able to order merchandise on the Internet, and a company that advertised its domain name was considered cutting edge. Today, Internet commerce is a fact of life, and ".com" stocks have gone through an entire boom and bust cycle.A host of new technologies ranging from optical switches to wireless networks are now becoming mainstream.

① 用EDA实训仪的I/O设备和PLD芯片实现数字日历的设计。
② 数字日历能够显示年、月、日、时、分和秒。
③ 用EDA实训仪上的8只八段数码管分两屏分别显示年、月、日和时、分、秒，即在一定时间段内显示年、月、日（如20080101），然后在另一时间段内显示时、分、秒（如00123625），两个时间段能自动倒换。
④ 数字日历具有复位和校准年、月、日、时、分、秒的按钮，但校年和校时同用一个按钮，即在显示年、月、日时用此按钮校年，在显示时、分、秒时则用此按钮校时，依此类推。

现在的快播电影站数以万计，但是99 都是靠采集而获得资源。采集，百度收录效果是很不理想的（因为大家的资源都是属于同一地址）。与其靠采集为生，还不如踏踏实实做个快播搜索站。百度一下，你会发现这样的站点现在很少（但是这类站点是喜欢用快播的网友常去的地方）。正所谓：一站在手，万站无忧！
所以，想做站的朋友，赶快行动（机不可失失不再来哦）！ 此类站点安装复杂，没耐心的朋友绕道，不想认真做的绕道……
