“…What does exist is largely inconclusive. Some preliminary assessments have found that QUIC facilitates a 100% increase in satellite broadband page load times compared to PEP-accelerated TCP [42]. However, others suggest that QUIC performs better, measuring up to a 50% decrease page load times [43].…”

Satellite broadband services are critical infrastructures, bringing connectivity to the most remote regions of the globe. However, due to performance concerns, many geostationary satellite broadband services are unencrypted and vulnerable to long-range eavesdropping attacks. This paper delves into the underlying cause of these issues, presenting the case that the widespread use of Performance Enhancing Proxies (PEPs) for TCP optimization has created a security/performance trade-off. A review of previous mitigation proposals finds limited real-world adoption due to a variety of factors ranging from misaligned commercial incentives to the prevalence of unverified "black-box" encryption products. To address these shortcomings, we design and implement a fully open-source and encrypted-by-default PEP/VPN hybrid, called QPEP. Built around the QUIC standard, QPEP enables individuals to encrypt satellite traffic without ISP involvement. Additionally, we present an open and replicable Docker-based testbed for benchmarking QPEP, and other PEP applications, through simulation. These experiments show that QPEP enables satellite customers to encrypt their TCP traffic with up to 72% faster page load times (PLTs) compared to traditional VPN encryption. Even relative to other unencrypted PEPs, QPEP offers up to 54% faster PLTs while also protecting communications in transit. We briefly discuss how QPEP might leverage bespoke modifications to the QUIC protocol for further optimization. Ultimately, our experiments suggest that QPEP's hybrid architecture represents a promising new technique for bringing both security and performance to satellite broadband while avoiding costly alterations to status-quo networks.

“…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.…”

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,
