Design and implementation of integrated ICN and CDN as a video streaming service

| openaire: EC/H2020/723172/EU//5GPagodaIn this research, we leverage the emerging concept of network slicing to enable the end-to-end integrated Information-Centric Networking (ICN) and Content Delivery Network (CDN) for 5G networking infrastructure. While CDN is deployed to cache content at the optimal server corresponding to the content and geographical location, this paper focuses on verifying the efficiency of ICN slice for regional content distribution. Specifically, the ICN slice can be established by the regional Orchestrator by following the current NFV/SDN standard. Then, the slice stitching process will be performed to interconnect two slices after their establishments via the Orchestrator. We also implement an OpenStack-based virtual node which supports both IP and ICN protocols and acts as the ICN-Gateway. The joint-testbed evaluations conducted between Japan side (ICN slice) and Europe side (CDN slice) show that the deployment of ICN Gateway and the proposed Node ID-based ICN naming structure can improve network performance and avoid network congestion.Peer reviewe
