[ndnSIM] red line shown in visualization

[Zeinab Rezaiefar]

  Hello,
I have implemented DFN topology in which each end node can be producer or consumer. I have ran topology with —vis . However , in the screenshot, when the simulation time is passed, i can see the red line which is going out from the node. (the snapshot is attachaed to this email)
 i am wondering what can be the reason for that.
is there any one knows that what is happening that this red line is shown during simulation time.
Thanks in advancebest regards
