“…Also, the study in [32] adopts the natural approach of "one bundle per block" for analysis and does not take into consideration the effect of bundle aggregation. However, our prior study [30,31] shows that bundle aggregation significantly improves BP/LTPCL performance over highly asymmetric channels, so we exercise that feature in our work with highly asymmetric space channel data rates. In addition, both the analysis and experimental verification in [32] are done for space communication scenarios with quite short signal propagation delay (up to 100 s); these research findings are not directly applicable to the very deep space communications which we target.…”

Delay/disruption tolerant networking (DTN) offers a solution to communications in "challenged" networks. Some work has been seen in evaluating the performance of DTN protocols based on simulated or emulated file transfer experiments. However, there is a need for a model of the performance of the DTN Licklider transmission protocol (LTP), which particularly targets reliable data transmission in deep space. In this paper, we present a performance model of LTP-based DTN data transmission in challenging communicationsManuscript characterized by extremely long signal propagation delay, lengthy link disruptions, and highly lossy channels that are typical of deep-space links. The model is verified by file-transfer experiments using a PC-based testbed.

“…In other words, the ground network, space network and the deep space network evolve independently and focus on their individual communication regimes. To address these issues, the National Aeronautics and Space Administration (NASA) has developed an integrated space system that integrates the Internet protocols, routers and interfaces into space networks [3] [4]. The space system, which is also called space Internet, enables large quantities of collaborative operations of those networks.…”

How to implement an impeccable space system-of-systems (SoS) internetworking architecture has been a significant issue in system engineering for years. Reliable data transmission is considered one of the most important technologies of space SoS internetworking systems. Due to the high bit error rate (BER), long time delay and asymmetrical channel in the space communication environment, the congestion control mechanism of classic transport control protocols (TCP) shows unsatisfying performances. With the help of existing TCP modifications, this paper contributes an aggressive congestion control mechanism.The proposed mechanism is characterized with a fast start procedure, as well as the feedback information to analyze network traffic and with a link terminating processing mechanism, which can help to reveal the real reason of packet loss, and maintain the size of congestion window at a high level. Simulation results are shown in the end to verify the proposed scheme.
