The diffusion of adaptive systems motivate the study of models of software entities whose interaction capabilities can evolve dynamically.
In this paper we overview the contributions in the ASCENS project in the area of software defined networks and of reconfigurable connectors.
In particular we highlight: (i) the definition of the Network-conscious pi-calculus and its use in the modeling and verification of the PASTRY protocol, and (ii) the mutual correspondence between different frameworks for defining networks of connectors together with two suitable enhancements for addressing dynamically changing systems
