写在最前
由于要用别人的项目代码来进行仿真，却不知道如何新建一个项目来跑自己的网络，故写下这篇文章。在inet的基础上，运行一个example上的例子。新建omnet++项目
新建test项目，empty project，之后直接按finish即可。
引用inet项目
对project 右键，properties。
新建ned
package tcptest;
import inet.networklayer.configurator.ipv4.IPv4NetworkConfigurator;
import inet.node.inet.Router;
import inet.node.inet.StandardHost;
import ned.DatarateChannel;
network net1
{

@display("bgb=400,200");
submodules:

}
server: StandardHost {

@display("p=350,100;i=device/server");
gates:

}
configurator: IPv4NetworkConfigurator;
connections:
router.pppg[0] <--> NormalPath <--> client.pppg[0];
router.pppg[1] <--> NormalPath <--> server.pppg[0];
}
channel NormalPath extends DatarateChannel
{
parameters:
datarate = 100Mbps;
delay = 0.0565us; // 10m
per = 0;
ber = 0;
}新建.ini配置文件
