WPF : One to many mapping and Vice Versa.

Hi, I am trying to do mapping for a hardware machine. Example, If there is a component A(Source - say 2 Ports) and a Component B ( Destination say 3 ports). Then how to map port of A to port of B. The condition is a single port of A can be mapped to multiple Port of B's, and vice versa. Any help will be very appreciable. Thanks.

 

[I tried (but not finding a solid solution) adding Port List to each machine (object). The 1st port of A should show 3 ports of B and THEN 2nd port of A should show 3 DifferenT ports of B. Also vice versa. ]
