I assume you mean Node-Port and Group-Port there?

Why are you proposing to make Node a subclass of Group?
I don't really see any practical reason for it, other than that it makes 
it esthetically more pleasing in the UML diagram, by having only one 
hasPort relationship.

I do agree that it makes sense for Groups to have a hasPort relation so 
that we can describe aggregated topologies.
