This presented work gives an overview on the FP7 project SAIL, that aims at designing architectures for the Future Networks. The conceptual developments in the work package - Open Connectivity Services (OConS) is the focus of this paper. OConS is proposing an open and flexible architecture framework for handling the connectivities in current and future networks. As exemplary studies, we applied OConS architecture framework to two scenarios: (1) the Mult-P transmission of 3GPP LTE connected with WLAN; (2) the extensions of ICN (Information Centric Networks) supporting Multi-P. They show the flexibility and the openness of OConS, and the benefits expected will be e.g. higher data rates, higher resource utilization and more reliable connectivity.
