随着中小型企业的高速发展，对网络处理和传输性能提出了新的要求。
由于网点接入路由器和终端接入设备年代较久，性能和扩展能力都出现了瓶颈，严重影响网点业务的发展和客户服务质量。
为此本论文设计了一个中小型企业的网络工程，从而解决了由于设备性能低下出现瓶颈的问题，而且提高了企业网络工程的扩展能力。
本论文首先讨论了中小企业网的背景、意义、应用现状以及研究与开发现状，然后对OSPF协议、DHCP协议、VLAN的划分、静态路由以及数据流控制等相关技术理论作了简单的论述，其次结合工程项目，论述了企业网络的需求分析、整体设计，其中包括对IP地质的划分，网络拓扑图等做了分析和描述。
接下来，论文着重讨论了基于OSPF协议的网络工程的设计和实现，详细地论述了各个协议的运用和实现方法。
最后，对整个网络进行了测试。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
