iperf -u for lte-wifi in ns3-dce

[tina]

Hi all,

-c

I am trying to use "dce-mptcp-lte-wifi" arcitechture for using iperf -u. My goal is that i can run "iperf -c 10.2.0.1 -u" and "iperf -c 10.2.1.1 -u". i deleted all manual routingtable sets and i added 

LinuxStackHelper::PopulateRoutingTables ();

although there was not any error with ./waf build and ./waf --run, but all pcaps were empty and no packet transferred in network.

so i did:

 "#include "ccnx/misc-tools.h" 

and following lines:

 Ipv4GlobalRoutingHelper::PopulateRoutingTables ();

LinuxStackHelper::PopulateRoutingTables ();

i will attach the program to this email. When "./waf build" i will receive following errors that i can't understand what is the reason could you please guide me?

It is strange because i attached the code here! but it seems it was not attached. However, there is the code here. I would grately appreciate if you can guide me.

Hi,

the reason of " error: call of overloaded 'setPos(ns3::Ptr<ns3::Node>, int, int, int)' is ambiguous" error was that the setpos function was defined in ccnx/misc-tools.h and also in my program.  but yet, when i deleted all manual linux routings, and i added

 Ipv4GlobalRoutingHelper::PopulateRoutingTables ();

LinuxStackHelper::PopulateRoutingTables ();

i have the following error i am using available image in docker (mptcp 0.89) so i think all the libraris and dependencies are installed correctly:

Please guide me how can i make routings with ns3 or linux kernel without doing that with linux?

Hi were you able to solve this issue
If yes can you please tell me the reason for empty pcap files.
