| Abstract Text | In the course of the global digitization in recent decades, the Internet has become one of the most important and ubiquitous communication means. However, being based on an end-to-end connectivity principle, existing internet infrastructure is not optimal for data, resp., content delivery use cases (such as Video-on-Demand): For such applications it is key to make the distribution of data from content producers towards multiple content consumers as efficient as possible. This fact has lead to the development of future Internet architectures part of the ICN (Information Centric Networking) family: ICN architectures, such as NDN (Named Data Networking), can improve content delivery on a systemic level, by - contrary to the classical internet - focusing on identified data and deploying in-network caching techniques. Replacing the entire established internet with a novel architecture is however a non-trivial task, which is why this thesis considers a layered network architecture consisting of several smaller NDN-based mobile networks (resp., domains): Thereby, independent domains are inter-connected using a Chord Peer-to-peer network running as an overlay on top of existing internet infrastructure. By using the NS-3 framework to develop a network simulation, which models real-world network characteristics, the performance of the proposed architecture is evaluated: This includes a comparison with a plainly NDN-based reference architecture, which reveals that the layered NDN & Chord approach is a valid and efficient alternative, if a global spanning NDN network cannot be realized, or, if NDN routing is subject to difficult conditions. |
