Poster: NDN+SCION: Global Name-based Routing

A practical inter-domain routing and forwarding system remains an open challenge for Named-Data Networking (NDN). At the same time, SCION is an emerging path-aware inter-domain routing and forwarding system designed to improve on the current Internet’s BGP-based system in several ways. Both NDN and SCION emphasize end-to-end security and trust, while also offering multipath capabilities. This leads us to consider network layer based on named data that uses NDN for intra-domain routing and forwarding, and SCION for inter-domain. Among the challenges to be overcome are where to implement the intra/inter-domain protocol transition, and how to scale the system to handle the vastly larger namespace of NDN. We describe a preliminary approach and lay out some key research questions.
