Compute the node where a packet should be forwarded.
[J,A] = NL_I_PathNextNode(I,P)
Current node location.
Connection path.
Next node location.
Acknowledgement.
NL_I_PathNextNode computes the node J where the packet under consideration located inside the node I should be forwarded. When J coincides with the connection destination node, A rates 1. Else it is 0.
