omnet++ - 在 SimuLTE 切换示例中添加多个文件传输 DL-UL 通信

Question

我正在尝试在 SimuLTE 切换示例中添加一个以上要模拟的下载上传链接，特别是在文件传输 DL-UL 场景中，我更改了 .ini 文件：

#
# Communication (TCP) from ue11 to ue21 (static)
#
[Config FileTransfer-DL_UL]
extends=Handover-General

*.ue11.numTcpApps = 1
*.ue21.numTcpApps = 1

#============= Application Setup =============
# Transmitter
*.ue11.tcpApp[*].typename = "TCPSessionApp"
*.ue11.tcpApp[*].localPort = 1000
*.ue11.tcpApp[*].sendBytes = 1GiB
*.ue11.tcpApp[0].tOpen = uniform(0.010s,0.1s) 
*.ue11.tcpApp[0].tSend = uniform(0.15s,0.5s) 
*.ue11.tcpApp[0].connectAddress = "ue21" 
*.ue11.tcpApp[0].localAddress = "ue11" 

# Receiver
*.ue21.tcpApp[*].typename = "TCPSinkApp"
#------------------------------------#

对此：

#
[Config FileTransfer-DL_UL]
extends=Handover-General

*.ue11.numTcpApps = 1
*.ue21.numTcpApps = 1

*.ue31.numTcpApps = 1
*.ue32.numTcpApps = 1

*.ue41.numTcpApps = 1
*.ue42.numTcpApps = 1

*.ue51.numTcpApps = 1
*.ue52.numTcpApps = 1

*.ue61.numTcpApps = 1

*.ue72.numTcpApps = 1

*.ue41.tcpApp[0].tSend = uniform(2.15s,2.5s) 
*.ue41.tcpApp[0].connectAddress = "ue42" 
*.ue41.tcpApp[0].localAddress = "ue41" 

*.ue51.tcpApp[0].typename = "TCPSessionApp"
*.ue51.tcpApp[0].localPort = 1000
*.ue51.tcpApp[0].sendBytes = 10MiB
*.ue51.tcpApp[0].tOpen = uniform(0.010s,0.1s) 
*.ue51.tcpApp[0].tSend = uniform(0.15s,0.5s) 
*.ue51.tcpApp[0].connectAddress = "ue52" 
*.ue51.tcpApp[0].localAddress = "ue51" 

*.ue61.tcpApp[0].typename = "TCPSessionApp"

*.ue91.tcpApp[0].tSend = uniform(0.15s,0.5s) 
*.ue91.tcpApp[0].connectAddress = "ue92" 
*.ue91.tcpApp[0].localAddress = "ue91" 


# Receiver
*.ue21.tcpApp[0].typename = "TCPSinkApp"

*.ue32.tcpApp[0].typename = "TCPSinkApp"


*.ue42.tcpApp[0].typename = "TCPSinkApp"
*.ue52.tcpApp[0].typename = "TCPSinkApp"
*.ue62.tcpApp[0].typename = "TCPSinkApp"
*.ue72.tcpApp[0].typename = "TCPSinkApp"
*.ue82.tcpApp[0].typename = "TCPSinkApp"
*.ue92.tcpApp[0].typename = "TCPSinkApp"
**.tcpApp[*].tClose = -1s

模拟时间设置为 20 秒。问题是，当模拟完成并打开标量时，我看到只有 ue11 和 ue61 正在发送任何数据，而 ue21 是唯一收到任何数据包的人。谁能帮助我并告诉我我做错了什么？谢谢

好吧，谈论愚蠢，使用 cmdenv 我忘记了我将 eNode 放置在离 UE 太远的地方，这就是我遇到这个问题的原因 :')
