网络工程拓扑绘制规范(PPT版)精选版
网络工程拓扑绘制规范具有标准化、统一化、规范化的特点，能够确保绘制出 的拓扑图清晰、准确、易于理解和使用，为网络工程的规划、设计、实施和管 理提供有力支持。
拓扑绘制的原则
准确性
拓扑图必须准确地反映网络的物 理和逻辑结构，包括设备的位置
、连接关系和配置信息等。
简洁性
拓扑图应简洁明了，避免过多 的细节和无关信息，突出重要 的结构和关系。
可读性
拓扑图应具有良好的可读性，使 用标准的符号和标记，确保不同 的人员都能快速理解和使用。
更新及时
随着网络设备和连接关系的变 更，拓扑图应及时更新，保持
与实际网络的一致性。
03
拓扑绘制的工具和技术
手工绘制工具
笔和纸
使用笔和纸进行手工绘制是最基本的工具，适用于快速草图 和概念设计。
绘图软件
如Microsoft Visio、Adobe Illustrator等绘图软件，适用于 制作详细和专业的拓扑图。
多层和动态拓扑表示
多层拓扑
支持多层网络拓扑的表示，包括核心层、汇聚层和接入 层等，以便更好地展示网络层次结构。
动态拓扑
能够实时更新和展示网络拓扑的变化，提供动态的网络 视图，方便对网络故障和性能问题进行快速定位和排查 。
THANKS
感谢观看
突出关键信息
使用不同的颜色、形状或大小来突出关键设 备和连接。
遵循标准
遵循行业标准，如ONF、IEEE等，以确保拓 扑图的准确性和一致性。
更新和维护
定期更新拓扑图以反映网络的变化，并保持 拓扑图的准确性。
04
实际案例分析
企业网络拓扑案例
总结词
企业网络拓扑案例展示了大型企业网络架构的复杂性，包括核心层、汇聚层和接入层的布局和设计。

防火墙asa基本设置
asa特点： • （1）从高安全级别接口到低安全级别接口的流量叫outside 流量，这 种流量默认是允许的 • （2）从低安全级别接口到高安全级别接口的流量叫inbound流量，这 种流量默认是不允许的，但我们可以使用ACL来放行inbound流量 • （3）相同安全级别的接口之间的流量默认是不允许的，但是可以用 命令打开 • （4） 安全级别的范围为0-100 • （5）默认inside安全级别为100，其余接口默认为0

批注：一个专业、规范的网络逻辑拓扑能够 非常直观的呈现网络架构，是行业基本要求； 另外也是工程师专业技能的体现；再者也是 个人品牌形象的体现。我们不要求拓扑做得 有多美观多牛逼，但是至少……不能太丑对 吧？

关于PPT绘制网络拓扑的建议
PPT在网络工程行业日常工作中的应用是非常 普遍的，我们不要求PPT的制作如何美观，如 何艺术，但是起码要有一定的专业度和可阅读。 因此对于这项技能我们的态度是，要锻炼，但 是不要沉迷，又特么不是搞艺术的对吧？别像 我啊……文艺气质过重
