“…The bundling protocol is currently being developed to work in a store-and-forward mode for the delay-tolerant networking (DTN) [17,18] architecture which incorporates tiered automatic repeat request (ARQ) and tiered congestion control techniques to achieve reliable transmission and congestion control for deep-space Internet links. Additional work in the development of space networks and Internet can be found in two recent special issues of the IEEE Journal on Selected Areas in Communications [20,21]. The above developments, especially the recently developed protocols, need to be thoroughly evaluated prior to actual deployment, as suggested as one of the main future research topics in space Internet by Akyildiz in [22].…”

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.

Being both wireless and mobile, low Earth obiting (LEO) satellite access networks have a unique set of link errors including bit corruption, handoff, and limited connectivity. Unfortunately, most transport protocols are only designed to handle congestion-related errors common in wired networks. This inability to handle multiple kinds of errors results in severe degradation in effective throughput and energy saving, which are relevant metrics for a wireless and mobile environment. A recent study proposed a new transport protocol for satellites called STP that addresses many of the unique problems of satellite networks. There was, however, no explicit attempt to implement a differentiating error control strategy in that protocol. This paper proposes grafting a new probing mechanism in STP to make it more responsive to the prevailing error conditions in the network. The mechanism works by investing some time and transmission effort to determine the cause of error. This overhead is, however, recouped by handsome gains in both the connection's effective throughput and its energy efficiency.

“…These high data rates are offered through high-bandwidth geostationary earth orbit (GEO) satellite links. Through their easily scalable architecture and multicast capabilities [3], heterogeneous broadband GEO satellite networks provide global Internet access and coverage to areas with limited or no terrestrial cable infrastructure. Heterogeneous networks with GEO satellite links are more attractive for continuous coverage than networks employing non-GEO (NGEO) satellite links because of lower development risks compared to large number of satellite constellations required by NGEO satellites [4].…”

Long propagation delays and high bit error rates in heterogeneous networks with geostationary earth orbit (GEO) satellite links have negative impact on the performance of Transmission Control Protocol (TCP). In this paper, we propose modifications to TCP by introducing adaptive delay and loss response (TCP-ADaLR) to mitigate the adverse effects of satellite link characteristics. The proposed modifications incorporate delayed acknowledgment (ACK) recommended for Internet hosts. TCP-ADaLR introduces adaptive window increase and loss recovery mechanisms to address TCP performance degradation in satellite networks. We evaluate and compare the performance of TCP-ADaLR, TCP SACK, and TCP NewReno, with delayed ACK enabled and disabled. In the absence of losses, TCP-ADaLR exhibits the shortest user-perceived latency for HTTP and FTP applications. In the presence of only congestion losses, TCP-ADaLR shows comparable performance to TCP SACK and TCP NewReno. In the presence of only error losses, TCP-ADaLR exhibits improvements up to 61% and 76% in throughput and utilization, respectively. In the presence of both congestion and error losses, TCP-ADaLR exhibits goodput and throughput improvements up to 43%. TCP-ADaLR exhibits the best performance in the absence of losses and in the presence of losses due to both congestion and errors. It also friendly to TCP NewReno, exhibits better fairness, and maintains TCP end-to-end semantics.
