This article proposes a discussion on the strengths, weaknesses, opportunities, and threats related to the deployment of QUIC end-to-end from a satellite-operator point-of-view. The deployment of QUIC is an opportunity for improving the quality of experience when exploiting satellite broadband accesses. Indeed, the fast establishment of secured connections reduces the transmission time of short files. Moreover, removing transport-layer performance-enhancing proxies reduces the cost of network infrastructures and improves the integration of satellite systems. However, the congestion and flow controls at end points are not always suitable for satellite communications due to the intrinsic high bandwidth-delay product. Further acceptance of QUIC in satellite systems would be guaranteed if its performance in specific use cases were increased. Based on an emulated platform and on open-source software, this paper proposes values of performance metrics as one piece of the puzzle. The final performance objective requires consensus among the different actors. The objective should at least provide acceptable performance for satellite operators to allow QUIC traffic but reasonable enough to keep QUIC deployable on the Internet.

QUIC：卫星通信中的机遇和威胁

本文从卫星运营商的角度讨论了与端到端 QUIC 部署相关的优势、劣势、机会和威胁。QUIC 的部署是在利用卫星宽带接入时提高体验质量的机会。事实上，安全连接的快速建立减少了短文件的传输时间。此外，去除传输层性能增强代理降低了网络基础设施的成本并提高了卫星系统的集成度。然而，由于固有的高带宽延迟产品，端点的拥塞和流量控制并不总是适用于卫星通信。如果 QUIC 在特定用例中的性能得到提高，将保证在卫星系统中进一步接受 QUIC。基于仿真平台和开源软件，本文提出了性能指标的值作为拼图的一部分。最终的绩效目标需要不同参与者达成共识。该目标至少应该为卫星运营商提供可接受的性能，以允许 QUIC 流量，但又足够合理，以保持 QUIC 可部署在互联网上。
