    Summary and wrap-up

Call For Participation

The future Internet is up in the sky. Since 2019, we have witnessed a rocket-fast deployment of the satellite mega-constellations for inter-networking in space, such as SpaceX Starlink, Amazon Kuiper, OneWeb, HongYun, to name a few. Such satellite networks promise competitive network capacity and latency to terrestrial networks, and complement them to offer global Internet coverage to users that were not easily reachable (e.g., rural areas, aircraft, and ocean).

This half-day lecture tutorial will provide a systematic overview of the integrated satellite-terrestrial networks' architecture, protocol, testbed, and standardization. We will review the state-of-the-art satellite networks and explain why it is necessary to integrate them with terrestrial networks. Then we will classify and enumerate the research challenges for integrated satellite-terrestrial networks. We next go through the recent research progress to address these challenges, including (but not limited to) physical-layer mega-constellation design, link-layer communications, network layer addressing/routing design, transport-layer deterministic networking, application-layer content delivery in space, and security across all layers. To facilitate the community on the experimentation and validation, we will demonstrate how to characterize the network behaviors with operational data-driven satellite-terrestrial network testbed we build based on CERNET 2/6IX and CNGI networks. We will also share our experiences of pushing forward the satellite network standards at CCSDS, IETF, and ITU with global mobile communication carriers and satellite operators. We wish this tutorial could call for the community's attention and stimulate more research for the integrated satellite-terrestrial networks.
