Satellite-based content delivery network (cdn) in an extraterrestrial environment

Abstract

Technology for satellite-based content delivery network (CDN) is described. The satellite-based CDN uses a network architecture to provide global high-speed Internet service from above the sky through various aircrafts such as high-altitude airships, satellites, space stations, and eventually the lunar data centers by taking into consideration of the technology advancements in the RF and optical wireless communications. The satellite-based CDN provides content delivery over data networks, aviation, data storage, and edge caching. The satellite-based CDN supports both the delay-sensitive traffic such as interactive services, voice calls, and video calls that consume medium to low data bandwidth, and the more delay-tolerant but high bandwidth Internet content items such as streaming and background services (e.g. email, FTP). The satellite-based CDN can also support highly time sensitive applications that require near real-time responses such as professional gaming in selected areas covered by the high-altitude airships.
