Title: Key Technologies in Dynamic Optical Satellite Networks

Abstract:
Satellite communication network is becoming an important information infrastructure for 5G and 6G. Space optical communications will be an inevitable choice for satellite communication networks, especially for inter-satellite communications, due to the capability of high speed and long distance transmission. However, because the satellites are always moving around the earth, the satellite communication networks topology is changing all the time including the inter-satellite link (ISL) distance and ground-satellite link (GSL) connection, which brings many challenges for the satellite communication networks. This talk covers topics of control architecture, routing algorithm, signaling protocol, and survivability mechanism of satellite optical communication networks.
