“…Many efforts have been directed to adapting the Internet Protocol (IP) suite, in particular the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) to different space applications leading to notable results such as SCPS-TP [8], TCP-planet [2] and Saratoga [9]. These works, together with literature on Delay-Tolerant Networking (DTN) [10] discuss the poor performance of the IP suite in space environments due link disruption, intermittent connectivity and large delays.…”

Novel distributed space mission concepts such as fractionation and federation promise to transform the design and operations approach of future missions. These paradigms require robust communications networking among other technologies. For the first time this paper explores the specifics of communications network protocols to enable Federated Satellite Systems using an opportunistic resource exchange frame open to all kinds of missions. Within satellite federations, participant spacecraft trade resources on a voluntary basis open to collaborative and/or commercial returns. The heterogeneous, mobile, flexible and scalable environment of satellite federations requires networking technologies capable of handling autonomous node discovery and frequent link disruptions. This work leverages existing Mobile Ad-Hoc Networking techniques to propose an FSS network protocol concept making use of OSLR neighbor sensing and store-carry-and-forward BATMAN routing concepts combined with link availability assessments and predictive topology routing. The performance of this protocol is tested through a dedicated network simulator and the FSS simulation toolkit. Results show the benefits of using FSS under this protocol. For a LEO-based scenario, average content delivery latency is improved from 41 minutes to 3.7 minutes by full usage of federated network benefits. Intermediate scenarios, such as 50% time network usage, present an average latency of 18 minutes. The paper ends by highlighting conclusions and next steps for the development of space communications protocols suitable for FSS.

“…Also, we suggest using ssthresh to avoid premature exit from Slow Start phase. In [21] authors compare the performance of TCP and their implementation of SCPS-TP SNACK (Selective Negative Acknowledgement) over paths with different BER and different delays. They present the improvement in throughput and link utilization when the SCPS-TP SNACK instead of standardized TCP mechanisms are used.…”

Satellite communications represent an important slice of the global communications sector thanks to their broadcast nature. Unfortunately, TCP used on satellite links suffers from a number of well-known performance issues, especially for high altitude satellites with longer delays. In this paper, a new TCP protocol is proposed. This new protocol arises after a careful study of the various protocols present in literature that try to resolve the typical satellite issues. Our TCP protocol is called Available bandwidth adaptable Transport Protocol (ATP) and it takes the advantages of two TPC protocols proposed in literature: Satellite Transport Protocol (STP) and TCP Jersey. In particular, it consists of a reviewed version of STP protocol with the addition of the TCP Jersey Bandwidth Estimation algorithm called Available Bandwidth Estimation (ABE). In order to show the goodness of the proposed protocol we have performed some comparisons between ATP, STP, TCP Jersey and another TCP protocol called Satellite Communication Transmission Protocol (SCPS-TP).
