“…With encrypted transport layer headers, as it is the case for VPNs and QUIC [4], PEPs can not be applied anymore. This leads to significant performance degradation described in earlier publications [5], [6], [2], [7], [8], [9], [10] and this work. Research, like [11], [12], that neglects the fact that PEPs are usually used to accelerate TCP connections, conclude that QUIC outperforms TCP on these satellite links.…”

“…However, compared to other Internet access technologies, geostationary satellites suffer from high propagation delays. Together with other delays, Round-Trip Times (RTTs) of 600 ms and more are typical [2]. Obviously, latencysensitive applications are inherently problematic for GEO satellites, but also the performance of transport protocols like TCP is problematic over high-delay links because of slowstart and long feedback loops.…”

QUIC was recently standardized as RFC 9000, but the performance of QUIC over geostationary satellite links is problematic due to the non-applicability of Performance Enhancing Proxies. As of today, there are more than a dozen of different QUIC implementations. So far performance evaluations of QUIC over satellite links were limited to specific QUIC implementations. By deploying a modified version of the IETF QUIC-Interop-Runner, this paper evaluates the performance of multiple QUIC implementations over multiple geostationary satellite links. This includes two emulated ones (with and without packet loss) and two real ones. The results show that the goodput achieved with QUIC over geostationary satellite links is very poor in general, and especially poor when there is packet loss. Some implementations fail completely and the performance of the other implementations varies greatly. The performance depends on both client and server implementation.

“…Unfortunately, this becomes problematic in scenarios where proxies are used to enable connection splitting, as in wireless networks (we discuss this in more detail in Section I-B). In these settings, QUIC's performance diminishes versus connections carried over TCP and secured with TLS [9], [10]. Thus, while QUIC brings several benefits to remote networks, its encryption policies offset those advantages.…”

G lobal connectivity is at an all-time high, and more users than ever before are participating in the online ecosystem. Despite this exciting phenomenon, opportunities to access the online world are not shared equally among the global population. Socioeconomic, political, and geographic factors all play roles in determining the extent to which one can be an online participant [1]. This resultant digital divide creates a social disparity between those who have reliable access to online content and can take advantage of all that the Internet has to offer and those who do not and miss out on those opportunities [2].For isolated, remote communities (RCs) such as those found throughout Canada's north, the digital divide continues to be an issue due to the prohibitive costs of building network infrastructure into these regions [1]. Despite its costs,

“…QUIC can then achieve fairly good performance for short files. However, QUIC does not outperform TCP proxy solutions for large pages [13], [14] in satellite broadband systems. Since QUIC is encapsulated in UDP, it does not take benefit from TCP PEP optimizations.…”

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 short files transmission time. 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 is increased. We propose a running code for an IETF document, and based on an emulated platform and on open-source software, this paper proposes values of performance metrics just as one piece of the puzzle. The final performance objective requires consensus among the different actors. The objective should be challenging enough for satellite operators to allow QUIC traffic but reasonable enough to keep QUIC deployable on the Internet.
