The 5GPPP association has decided to organise open workshops in order to allow outside projects to present their visions and contributions to future 5G networks. In this sense, the first open 5G architecture workshop will be held in Brussels on 06/04/2016. Xavier Artiga (CTTC) will present the SANSA network concept focusing on the functionalities of the Hybrid Network Manager and Intelligent Backhaul Node that are being developed within the project activities. In addition, the presentation will also address some open issues of a potential integration of SANSA in overall 5G architectures based on SDN/NFV techniques.
