“…Furthermore, the changes are transparent to routers, and the end-to-end semantic of TCP remains unchanged. Typical solutions involving only TCP modifications and extensions are: Stream Control Transmission Protocol (SCTP) [6], Satellite transport protocol (STP) [7], extended STP (XSTP) [8], TCP Peach [9], TP-Planet [10], and TCP Westwood (TCPW) [11]. Among these solutions, STP and XSTP involve changes only to error-control algorithms, and SCTP changes both the error-control and congestion-control algorithms, while the rest of the protocols involve changes to only congestion-control algorithms.…”

A variety of protocols have been proposed for reliable data transport in space Internet and similar network environments. It is necessary to conduct a survey on these protocols to investigate and compare among them. In this article, we present a survey on the protocols proposed for reliable data transport in space Internet, with a focus on the latest developments. The survey includes the following contents: (1) Classification of these protocols into different approaches; (2) Discussions and comments on the design and operation methods of the protocols; and (3) Comparisons and comments on the main techniques and performance of the protocols.

“…STP has no mechanism to differentiate packet losses caused by link congestion and bit error corruption. The extended STP (XSTP) [9] recently proposed by Elaasar et al solves the error control problem of STP using an end-to-end probing mechanism. Both STP and XSTP involve the protocol conversion to and from STP at border gateway, making them very complex.…”

Space Communication Protocol Standards (SCPS) has been developed for the reliable transfer of information in the space Internet. There is a need to have an evaluation of the SCPS protocol in a realistic space environment with a large bandwidthdelay product (BDP). An experimental evaluation of SCPS-TP was done by transferring user files using the SCPS protocol over the NASA's Advanced Communications Technology Satellite (ACTS) links. However, the user files were so small that the steady performance of the protocol could not be accurately evaluated. This paper describes an experimental evaluation of SCPS-TP over high-speed, asymmetric space links by transferring a large user file over asymmetric ACTS link, leading to its steady performance.

“…Several window-based congestion control mechanisms [5][6][7][8][9][10][11][12][13][14][15][16] have been proposed for space Internet, but these mechanisms have not been deployed yet due to various reasons. While the window-based mechanism is not favorable in a space environment characterized by a large BDP, the potential of the rate-based Internet-type protocols to have low loss by maintaining a smooth data flow has made them attractive in space communications.…”

“…The experimental work done using both simulations [21][22][23][24][25][26][27] and actual satellite links [25,27] shows that SCPS-TP has a much better performance than the conventional TCP, especially over error-prone links. Compared with the above congestion control mechanisms proposed for space networks [5][6][7][8][9][10][11][12][13][14][15][16], SCPS-TP can be configured to employ the window-based congestion control, rate-based congestion control, or a hybrid of the two. The details of each mechanism are provided in the next section.…”

Space communications urgently need an effective transmission control mechanism. This paper presents an experimental, comparative analysis of window-based transmission control, rate-based transmission control, and a hybrid of the two over error-prone, congestion-free, high-latency, point-to-point space communication links simulated using the space-to-ground link simulation (SGLS) test-bed. The results revealed that the traffic shaping mechanism of rate-based transmission protocol is more effective than the bursting flow of window-based protocol over simulated space communication links with a high error rate and a long link delay. The window-based transmission mechanisms show performance degradation due to traffic bursts and frequent packet retransmissions caused by their acknowledgment (ACK)-clocked transmission control algorithms. Pure rate-control is always preferable to other mechanisms in the simulated congestion-free, error-prone, point-to-point, geostationary-Earth orbit (GEO)-space communication channels, and its advantages become more pronounced when the channel rates are asymmetric. The performance differences come from their different behavior in controlling data transmission.of window-based and rate-based mechanisms over direct, point-to-point satellite links. In a general point-to-point satellite network, the only hop in the network is over the satellite channel with a guaranteed bandwidth capacity provided, and it only exhibits the problems associated with the satellite channels without the network congestion imposed as in the shared network [18]. Furthermore, we have been studying the performance of the mentioned transmission mechanisms over the dedicated, congestion-free, point-to-point communication links, especially in an environment with a high BER and high latency involved. A typical scenario of point-to-point space communication considers the satellite to be another node on the Internet. In this scenario, the ground-based satellite controller can transfer data files between the satellite and the ground control center just as if transferring files across the Internet. This will allow Earth-science and space-science instrument designers to organize data in normal file mode formats for instrument and housekeeping data and takes advantages of networking protocols to manage the data transfers [19]. As an example of application scenarios, satellites at the low Earth orbit (LEO) and geostationary-Earth orbit (GEO) may communicate with a ground station via a direct radio link in the point-to-point topology as shown in Fig. 1. As another application example, the direct, point-to-point link functions as the interplanetary communication backbone link between the outer-space planets and the Earth, as well as the Earth-based infrastructure elements such as a ground station for the deep space network. Please see [10] for a detailed discussion on this application.A space network protocol suite, Space Communication Protocol Standards (SCPS) [20], was developed under the Consultative Committee for Space Data Sy...
