A strategy is being developed whereby the current set of internationally standardized space data communications protocols can be incrementally evolved so that a first version of an operational "Interplanetary Internet" is feasible by the end of the decade. This paper describes its architectural concepts, discusses the current set of standard space data(More)
Delay and disruption tolerant networks (DTNs) may experience frequent and long-lived connectivity disruptions. Unlike traditional networks, such as the TCP/IP-based Internet, DTNs are often subject to high latency caused by very long propagation delays (e.g., interplanetary communication) and/or intermittent connectivity. Another feature that sets DTNs(More)
Controlling congestion is critical to ensure adequate network operation and performance. That is especially the case in networks operating in "challenged"- or "extreme" environments where episodic connectivity is part of the network's normal operation. Our goal is to study congestion control mechanisms that have been proposed for these so-called disruption(More)
Small satellite systems enable whole new class of missions for navigation, communications, remote sensing and scientific research for both civilian and military purposes. As individual spacecraft are limited by the size, mass and power constraints, mass-produced small satellites in large constellations or clusters could be useful in many science missions(More)
Unlike TCP/IP networks, in DTNs end-to-end paths between nodes cannot be guaranteed at all times. This means that DTN nodes may have to store messages for long periods of time before they can forward the messages towards their ultimate destinations. As a result, congestion control in DTNs is critical to achieve adequate performance, yet needs to be(More)
