根据实验报告截图(linux查看文件属性指令)中表现出来的文件大小,添加的Core抓包量几乎是0。
csma 4-0节点相比ppp的节点,抓包文件大小几乎就是一半,但是实验报告得出的结论确实这两个节点速率类似。
实验报告最后说:
``` 在此次实验中还遇到一些问题,如下,在模式一中添加 core 时,会有多条
可能的路由路径,需要用到 ECMP 路由协议,但是在代码最后加上下图中…

### 第一章 概述
**1-03 试从多个方面比较电路交换、报文交换和分组交换的主要优缺点。**
电路交换特点:面向连接的,优点是实时性好,缺点是资源利用率低,费用高
分组交换特点:分组交换技术,网络线路利用率高,缺点是实时性差一点。
报文交换特点:优点:数据以完整的报文形式进行传输,可以根据需要动态分配带宽。适用于短期大量数据传输,如文件传输。
缺点:由于每个报文都要等待完…
