“…The working group TCPSat [162] was created in 1997 to study the behavior of the TCP protocol over satellite links. It generated two documents, before closing in 2000: [163] (Enhancing TCP Over Satellite Channels using Standard Mechanisms) and [164] (Ongoing TCP Research Related to Satellites) which were published as Best Current Practice RFC in 1999 and Informational RFC in 2000, respectively.…”

This document surveys recent and current developments in Low Earth Orbit (LEO) satellite networking. It presents a brief overview of satellite networking in order to contextualize the issue. It then focuses on current research work in emerging domains, such as machine learning, Software-Defined Networking (SDN), low latency networking, green networking, Information-Centric Networks (ICN), etc. For each of these, it presents recent works and a direction of the research community within that emerging domain. The paper also describes the current state of standardization efforts in 3GPP and in IETF for LEO satellite networking. In particular, we present in some detail the direction these standards bodies are pointing towards for LEO networking with inter-satellites links. Finally, some future challenges and interesting research directions are described and encouraged. This is an overview of the current state of the LEO satellite research in both academic and industrial standardization environments which we believe will be helpful to understand the current state of the art.

“…There are numerous works on optimising TCP, the de facto protocol for data transmission for network paths with large bandwidth capacities and high delays, such as in satellite networks and space-ground networks. The Internet Engineering Task Force (IETF) has been active in this area, for example, RFC 2760 [67] specified ongoing TCP research for satellite communications, and more recently RFC 8975 [68] outlines work in network coding for satellites. More recent research also focuses on incorporating and modifying state-ofthe-art transport protocols and mechanism for satellite-based communications, such as Bottleneck Bandwidth and Round-trip time (BBR), Quick UDP Internet Connections (QUIC) and Multiplath TCP (MPTCP) [69][70][71].…”

Recent scientific and technological advancements driven by the Internet of Things (IoT), Machine Learning (ML) and Artificial Intelligence (AI), distributed computing and data communication technologies have opened up a vast range of opportunities in many scientific fields—spanning from fast, reliable and efficient data communication to large-scale cloud/edge computing and intelligent big data analytics. Technological innovations and developments in these areas have also enabled many opportunities in the space industry. The successful Mars landing of NASA’s Perseverance rover on 18 February 2021 represents another giant leap for humankind in space exploration. Emerging research and developments of connectivity and computing technologies in IoT for space/non-terrestrial environments is expected to yield significant benefits in the near future. This survey paper presents a broad overview of the area and provides a look-ahead of the opportunities made possible by IoT and space-based technologies. We first survey the current developments of IoT and space industry, and identify key challenges and opportunities in these areas. We then review the state-of-the-art and discuss future opportunities for IoT developments, deployment and integration to support future endeavors in space exploration.

Maximizing single connection TCP goodput by trading bandwidth for BER

SUMMARYAll other conditions being equal, the end-to-end throughput of a TCP connection depends on the packet loss rate at the IP level. This is an issue when IP runs on a wireless link, where the bit error rate is variable and typically much higher than it is on fixed links. Especially on physical links where the bandwidth delay product is high, TCP performance is significantly impaired by apparently low values of the bit error rate. Generally speaking, on a wireless link bandwidth can be traded for information quality (error rate), the simplest method being to change the type or parameters of forward error correction. On this basis, we show a general method of taking advantage of this trade-off in order to maximize the throughput of a TCP connection.
