Abstract. Current Future Internet (FI) research brings out the trend of designing information-oriented networks, in contrast to the current host-centric Internet. Information-centric Networking (ICN) focuses on finding and transmitting information to end-users, instead of connecting end hosts that exchange data. The key concepts of ICN are expected to have significant impact on the FI, and to create new challenges for all associated stakeholders. In order to investigate the motives as well as the arising conflicts between the stakeholders, we apply a tussle analysis methodology in a content delivery scenario incorporating socioeconomic principles. Our analysis highlights the interests of the various stakeholders and the issues that should be taken into account by designers when deploying new content delivery schemes under the ICN paradigm.

With the evolution of the Internet from a controlled research network to a worldwide social and economic platform, the initial assumptions regarding stakeholder cooperative behavior are no longer valid. Conflicts have emerged in situations where there are opposing interests. Previous work in the literature has termed these conflicts tussles. This article presents the research of the SESERV project, which develops a methodology to investigate such tussles and is carrying out a survey of tussles identified within the research projects funded under the Future Networks topic of the FP7. Selected tussles covering both social and economic aspects are analyzed also in this article. An Approach to Investigating Socio-economic TusslesArising from Building the Future Internet Abstract.

Trustworthiness of software and services is a key concern for their use and adoption by organizations and endusers. Trustworthiness evaluation is an important task to support making informed decisions for both providers and consumers, i.e., for selecting components from a software marketplace. An analysis of the state of the art in software evaluation technologies motivated us to develop an evidence-based approach for trustworthiness evaluation. Most of the literature evaluates trustworthiness by focusing on a single dimension (e.g., from the security perspective) while there are limited contributions towards multifaceted and end-to-end trustworthiness evaluation. Our analysis reveals that there is a lack of a comprehensive framework for comparative, multi-faceted end-to-end trustworthiness evaluation, which takes into account different layers of abstractions of both the system topology and its trustworthiness. In this paper, we provide a framework for endto-end trustworthiness evaluation using computational approaches, which is based on aggregating certified trustworthiness values for individual components. The resulted output supports in the definition of trustworthiness requirements for a software component to be locally developed and eventually integrated within a system, as well as, trustworthiness evidences for a composite system before the actual deployment. Thereby supports the designer in analyzing the end-to-end trustworthiness values. An application example illustrates the application of the framework.

Abstract. Over the past decades, the fundamental principles of the Internet architecture have not significantly changed. However, Internet evolution and its effects on participants' interests have triggered the need for re-defining these design principles. "Design for Tussle" is an aspiration for future network designs, which enables the involved stakeholders to express their possibly conflicting socio-economic preferences on service instances. We performed a series of case studies examining whether established technologies are compatible with this new approach. Using the knowledge gained, we provide canonical examples and help protocol and network designers better to consider how to come up to the problem of "designing for tussle" in order to realize a flexible architecture. Finally, we associate protocol success to adoption and show, using empirical evidences, that carefully embracing the "Design for Tussle" paradigm can outweigh the higher complexity in protocol design.
