论文摘要
低地轨道卫星已经获得了势头，以提供互联网连通性，从而增强了在悠久的地静止轨道中的连通性。同时，Quic已开发为Web的新运输协议。尽管Quic流量已完全加密，但诸如绩效增强代理（PEP）之类的中介（过去对于互联网而不是卫星性能必不可少），无法再篡改并优化运输连接。在本文中，我们提出了一个卫星模拟测试床，并使用它比较了QUIC和TCP以及HTTP/3和HTTP/1.1，具有和没有最小的PEP功能。随着时间的流逝，我们发现Quic PEP的速度较慢的启动阈值与QUIC非PEP相比，最高2 s。此外，我们发现在多个Web性能方案中，HTTP/3和HTTP/3-PEP优于HTTP/1.1和HTTP/1.1-PEP，其中HTTP/3-PEP在Edge案例中以超过7s的速度对HTTP/3的HTTP/3改进页面加载时间。因此，我们的发现暗示，这些性能提高可能值得探索Quic的PEP。
Low-Earth Orbit satellites have gained momentum to provide Internet connectivity, augmenting those in the long-established geostationary orbits. At the same time, QUIC has been developed as the new transport protocol for the web. While QUIC traffic is fully encrypted, intermediaries such as performance enhancing proxies (PEPs) - in the past essential for Internet over satellite performance - can no longer tamper with and optimize transport connections. In this paper, we present a satellite emulation testbed and use it to compare QUIC and TCP as well as HTTP/3 and HTTP/1.1 with and without minimal PEP functionality. Evaluating goodput over time, we find that the slow start threshold is reached up to 2s faster for QUIC PEP in comparison to QUIC Non-PEP. Moreover, we find that HTTP/3 and HTTP/3-PEP outperform HTTP/1.1 and HTTP/1.1-PEP in multiple web performance scenarios, where HTTP/3-PEP improves over HTTP/3 for Page Load Time by over 7s in edge cases. Hence, our findings hint that these performance gains may warrant exploring PEPs for QUIC.
