To evaluate the performance of the NFD, we try to use the traffic-generator provided with the NFD together. We wrote two configuration files according to "ndn-traffic-server.conf.sample" and "ndn-traffic-client.conf.sample". The only difference between our configuration files and the orginal configuration files lie on the number of the content in the files. Our files include 10 thousands of content. Then I started the nfd at the client and the server. Moreover, registered the name prefix by binding the sever ip.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:black'>There is an error ocured then with a msg that "error while connecting to the forwarder" (we have correctly run and compile NFD and </span><span style='font-size:10.5pt;font-family:"Helvetica",sans-serif;color:black'>ndn-traffic-generator</span><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:black'>).
