Conclusion

The deployment of QUIC is an opportunity to improve the quality of experience when using satellite broadband access. The rapid establishment of secure connections reduces transmission times for short files. In addition, the elimination of TCP proxies (PEPs) would reduce the cost of the core network and improve the integration of satellite systems into terrestrial systems.

However, congestion and flow controls at the end points are not always suitable for satellite communications, due to the high bandwidth-delay product. Further acceptance of QUIC in satellite systems would be guaranteed if its performance in these specific use cases were improved.

This article did not consider satellite access based on a constellation of low-earth orbit satellites. The impact of deploying QUIC on a constellation of LEO satellites would be similar for a cellular...
