omnet++ - 如何实现复合模块向量（包括路由器、主机、移动模块等）之间的路由功能？
问题描述
如何实现复合模块向量（包括路由器、主机、移动模块等）之间的路由功能？例如，如何连接内部和外部复合模块向量？网络中间的复合模块如何转发数据？
1.我在 Ubuntu 18.04 上使用 omnet++5.4.1 和 inet4.0
- 我正在使用卫星模拟模块-os3。这里是卫星模块代码和 SatSGP4 网络代码，omnetpp.ini 代码。
package os3.base;
//import inet.base.NotificationBoard;

import os3.mobility.SatSGP4Mobility;
import inet.node.ethernet.Eth1G;
module Satellite
{
parameters:
@nodes();
@node; //because of MobilityBase initialization
string satelliteName = default(""); // Parameter for satellite name
string mobilityType = default("SatSGP4Mobility"); // Define mobility module
// Transmit Power of satellite (7dBW as example for CospasSarsat system)
double transmitPower @unit(dBW) @display("i=device/satellite;bgb=324,226") = default(7dBW); // Symbol
@display("t=$satelliteName;bgb=688,367");
gates:
//input radioIn; // Input gate
//output radioOut; // Output gate
inout ethg[];
submodules:
mobility: <mobilityType> like IMobility { // Module for mobility (parent class -> BasicMobility), BasicMobility -> IMobility
@display("p=57,109");
}
//mobility : SatSGP4Mobility {
// parameters:
// @display("p=194,103");
//}
// notificationBoard: NotificationBoard { // Module for event notification
// parameters:
// @display("p=221,94");
// }
NoradModule: Norad { // Module for transformation between omnet and libNorad

@display("p=51,36");
}
host: StandardHost {
@display("p=204,101");
}
router: Router {
@display("p=204,233");
}
connections allowunconnected:
host.ethg++ <--> Eth1G <--> router.ethg++;
// towards other areas
router.ethg++ <--> ethg++;
}

我希望卫星 [0] 的主机将 tcp 数据传输到卫星 [2] 的主机，但它不能这样做。当我运行 ini 文件时，在卫星 [0] 中，主机发送 arpREQ 到路由器，路由器接收 arpREQ并向主机发送arpReply，但是当主机再次向路由器发送SYN时，路由器发送ICMP-error-#3-type3-code0。链接错误或设置ini错误或其他错误？提前谢谢您的帮助。
