These requirements have streamlined the design of a novel (yet not revolutionary) architecture framework based on the identification of functional entities and their interfaces. The most distinguishing feature is its flexibility, allowing its adaptation to already existing protocols/technologies/algorithms as well as to novel solutions. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.enDesign GuidelinesFuture InternetOpen Connectivity ServicesInformatikConference Paper10.1007/978-3-642-30422-4_7Other
