The Space-Terrestrial Internetworking Workshop (STINT) addresses emerging technical topics related to packetized, multi-path, multi-hop data exchange between and amongst space-based and terrestrial network nodes. Such networks accept space assets as first-class nodes performing common network functions such as stateful packet inspection, routing, management, and security. Full research papers, demonstrations, and presentations will be solicited for the protocols, applications, and operational concepts required to make these internetworks both technically feasible and operationally deployable.
