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 intradomain 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.
