Much has been made for the potential for blockchain technologies to improve the security, scalability, and economics of distributed data delivery. The CacheCash experiment proposes to understand the real-world feasibility of such technologies by deploying a cutting edge blockchain-based content distribution network (CDN) to distribute open source software to real world users. In this way, we will be able to evaluate the strengths of such approaches, the weaknesses, and to identify research challenges that must be tackled to allow these technologies to become widespread.

Multi-Carrier Cellular Access (MCCA) providerssuch as GoogleFi irruptedrecentlyin the mobile Internet access market claiming to offer enhanced performance at reduced prices. MCCAproviders dynamically attach to different carriers based on real time measurements of performance.The goal of the project is to do an experimental comparativestudy ofthe performance of these emerging MCCAproviders and the incumbent cellular providerswith a specialfocus on the performance while roaming.The proposed methodology is to acquire MCCAservices and traditional mobile services in the US and experimentallycompare theirperformance bothat home (US) and while roaming (EU).

The SCN4NDN project will experiment with the merger of two promising NGI technologies: Information-Centric Networking (ICN) and Decentralized Identifiers (DIDs) ICN has been on the spotlight of many research efforts for more than a decade. It has been explored as a standalone future Internet architecture, as well as an enabler for other NGI architectures, including 5G, IoT, and architectures focused on big dataand/orcyber security. ICN’s goal is to enable fast and secure content dissemination by leveraging direct and intrinsic information identification; this allows supporting multicast, multipath, and caching, as well as novel trust mechanisms.
