Petri net structures are used as communication model of network systems where message transfer channels are represented by the nets' edges, communicating agents-by nets' places and actions of communication-by nets' transitions, which here are called transmissions. The role of structured tokens play send/receive statements, that arrive at random, which makes the distribution of edges change dynamically. In this sense a net is self-modyfying: although the set of agents-places is fixed, the channels and communicating actions vary in the course of the net activity. Problems of deadlock and fairness is investigated.
