Aggregation of DTN Bundles for Channel Asymmetric Space Communications

Free registration required

Executive Summary

Delay/disruption Tolerant Networking (DTN) is considered one of the most suitable technologies to handle challenging space communications. Aggregation of multiple DTN bundles within a data transport block for space communications has been in controversy for years. In this paper, the authors present an experimental investigation, using a PC-based testbed, of whether aggregation of multiple DTN bundles within a single Licklider Transmission Protocol (LTP) block has performance advantage over the default approach of "One bundle per block" for channel-rate asymmetric cislunar communications.
