[ndnSIM] Node adjacency matrix in ndnSIM, how?

Hi (Alex, Spyros),
In all ndnSIM examples, the interconnection links between nodes is
specified as:
# srcNode dstNode bandwidth metric delay queue
Node0 Node1 1Mbps 1 10ms ns3::RedQueue,MeanPktSize=100
Node0 Node3 1Mbps 1 10ms ns3::RedQueue,MeanPktSize=100
In all these configs, is the adjacency between the two nodes and all the
link characteristics defined as bidirectional by default? Is it a ndnSIM
requirement to specify the links parameters as defined in all the examples
or it is specific to application?
Can we define the links and their parameters in each direction and how does
ndnSIM would behave in such case? For example, how to achieve this:
# srcNode dstNode bandwidth metric delay queue
Node0 Node1 1Mbps 1 10ms ns3::RedQueue,MeanPktSize=100
Node1 Node0 2Mbps 1 20ms ns3::RedQueue,MeanPktSize=200
Node0 Node3 1Mbps 1 10ms ns3::RedQueue,MeanPktSize=100
Node3 Node0 2Mbps 1 20ms ns3::RedQueue,MeanPktSize=200
My application scenario, each node define its own adjacency matrix and link
parameters (i.e. application specific configuration), thus takes care of
creating and initializing the faces in each direction explicitly. While I
believe in real set up it would fine; however, in case of ndnSIM I am not
sure how it is going to behave.
Can you please elaborate?
