Hi Zeinab,

Which version of ndnSIM you're using.  For ndnSIM 1.0 your reasoning is almost correct.  There could also be face related to the application, if you have an application installed.  If a node doesn't have an application, then there should be just one face per simulated connection.

ndnSIM 2, in addition to faces that correspond to network interfaces and applications, there are also several internal faces (internal face for management, face to represent content store, null face).

In my point of view , this node should have one interface, however, when I print interface of the interest message that is received in forwarding function. ( using inFace->GetId () for interface related to the interest message and node->GetId () for the node id).  I recognized that node 1 received interest messages from interface1 and 0.
