video streaming: no matching function for call to ‘ns3::UdpTraceClientHelper

[noorm...@gmail.com]

Dear NS3 team,

I am new to the NS3. I have studied the tutorials and examples inside the ns3 documentation and it helped me a lot.
However, problem started when I'm trying to mimic a video streaming by editing the third.cc code and the udp-trace-client-server.cc example code.
I started to get the following error as per attachment. At first, I thought it is due to the path assign for the trace file. For your information, I save the Verbose_Simpsons.dat in the scratch folder.
However, when I tried to replace the trace file (Verbose_Simpsons.dat) into the  UdpTraceClientHelper client (serverAddress, port,"Verbose_Simpsons.dat"); of the udp-trace-client-server.cc, the code  works successfully.
I tried to look into the forum and the manual. But I couldn't find the answer and I have no idea at all why it is happened.

Could anyone of you help or advise me on this. The code is as below:

Hi,

The signature for UdpTraceClientHelper according to the API is as follows:

UdpTraceClientHelper (Address ip, uint16_t port, std::string filename)

However, when you call it you do not use the IP address, but an InterfaceContainer.

  client = UdpTraceClientHelper (csmaInterfaces,port,"Verbose_Simpsons.dat");

You need to replace the csmaInterfaces, with the single IP address of the remote host.

Second issue, is that the file name has to be relative to where you call the scenario, and since you call it from the base ns-3 you will need to add "./scrach/Verbose_Simpsons.dat" if the file is in scratch.

Regards

K.

Hi Konstantinos,

Thank you for your help. I will look into it once again as highlighted by you.
