“…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. Moreover, neither long link disruptions nor severe channel-rate asymmetry is considered in the analytical performance formulation and experiments of bundle transmission in [32].…”

“…In [32], Bezirgiannidis et al presented a method of estimating data bundle delivery time in space internet working using the contact graph routing (CGR) route computation algorithm. Unlike our work focusing on LTP, the analysis in [32] is done at the BP layer focusing on estimation of end-to-end bundle delivery time rather than hop-to-hop LTP data block transmission time. 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.…”

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.

“…Along these lines, authors in [1] propose BDTE, an administrative tool to estimate bundle delivery time, based on both deterministic and stochastic components. BDTE integrates well known schedules and unexpected channel errors that affect significantly end-to-end delivery latency; however, it does not account for queueing delay.…”

AlthoughInterplanetary Telecommunications rely on preconfigured contact schedules to make routing decisions, there is a lack of appropriate mechanisms to notify the network about contact plan changes. In order to fill this gap, we propose and evaluate a framework for disseminating information about queueing delays and link disruptions. In this context, we present such a mechanism, focusing not only on its functional properties, but rather on its impact objectives: to improve accuracy and routing performance. Supportively, we couple this mechanism with a DTN-compatible protocol, namely Contact Plan Update Protocol (CPUP), which implements our dissemination policy. Through simulation of space scenarios we show that accuracy can be significantly improved in all cases while routing performance can achieve a wide range, from minor through to significant gains, conditionally.

Summary In this work, we propose an end‐to‐end retransmission framework for dynamically calculating efficient retransmission time‐out intervals in delay‐tolerant networks (DTNs) with scheduled connectivity. The proposed framework combines deterministic and statistical information about the network state to calculate worst‐case estimates about the expected round trip times. Such information includes connectivity schedules, convergence layer protocols specifics, communication link characteristics, and network statistics about the maximum expected packet error rates and storage congestion. We detail the implementation of the proposed framework within the end‐to‐end application data conditioning layer proposed for the DTN architecture, realized by the Delay‐Tolerant Payload Conditioning protocol, as part of the Interplanetary Overlay Network–DTN reference implementation, and evaluate its performance in a complex deep‐space emulation scenario in our DTN testbed. Our results show that our approach achieves great accuracy in round‐trip time estimations and, therefore, faster retransmissions of lost data, in comparison to the statically configured retransmission mechanism of the original Delay‐Tolerant Payload Conditioning protocol. As a result, in‐order data reception rate and storage requirements on the receiver side are significantly improved, at minimum or even zero extra cost in transmission overhead due to duplicate transmissions.
