bootstrap:存储在ROM中的微码(microcode)中,用来在初始化的时候启动router,然后加载IOS
POST:存储在ROM中的微码中,用来检查硬件基本配置是否正常,然后决定哪些接口可用
ROM monitor:存储在ROM中的微码中,作用是测试和排疑等
Mini-IOS:Cisco叫它RXBOOT或bootloader,它是存储在ROM中的,IOS的简化版本,用来把IOS加载到闪存中
RAM(random-access memory):用来保存数据包

整个无线通信演示系统由ABCD四个节点组成,根据硬件前端的实现,每个节点在收到与自己地址对应的数据包时触发同步信号,所以就需要一个中心节点来进行同步触发,本系统中以A节点为中心节点,B、C、D三个节点地位对等。A节点周期性的广播同步信息,从而实现四个节点的同步。A节点连接一台PC机,用来监视网络的情况并显示从其它节点发送过来的图像流信息。该软件可以实时对串口进行监听并显示A节点的路由表、网络的时隙表和吞吐量,实时获得B、C、D三个节点的图像流数据。-The wireless communica
