我是靠谱客的博主舒服毛衣，这篇文章主要介绍OMNET++基础知识一，现在分享给大家，希望可以做个参考。

常用import和export导入导出文件
tictoc1的学习
在这里插入图片描述

simple Txc1
//通过simple构建了一个节点
{
gates: //节点有两个门
input in;//输入门
output out;//输出门
}
//
// Two instances (tic and toc) of Txc1 connected both ways.
// Tic and toc will pass messages to one another.
//
network Tictoc1//构造一个网络，网络名称叫做Tictoc1
{
@display("bgb=147,150");//display可以理解为显示
submodules:
tic: Txc1 {
@display("p=31,36");
}
toc: Txc1 {
@display("p=91,83");
}
connections://两个节点如何连接
tic.out --> {
delay = 100ms; } --> toc.in;
tic.in <-- {
delay = 100ms; } <-- toc.out;
}
