Abstract

Satellite Internet with geostationary satellites is one way to provide Internet access all over the world. In Europe, there are three major satellite operators. In this paper, their performance is compared with respect to one-way delays, bulk data transfers, and website download times. When one-way delays are measured with UDP packets, the forward link generally shows lower delays than the return link. The bulk data transfers reveal how close actual data rates get to the advertised link rates. Regarding website download times, the web protocols HTTP/1.1, HTTP/2, and QUIC are considered. The results of our TCP measurements show that satellite Internet heavily relies on Performance Enhancement Proxies (PEPs). TCP connections over VPN tunnels cannot benefit from PEPs and therefore result in poor performance. QUIC can perform better than TCP tunneled in VPNs, but performs worse than TCP connections optimized by PEPs. One operator generally shows more stable performance regarding delays, data rates and page load times.
