摘要

摘要:我们使用容忍延迟网络(DTN)来打破空间-地面通信链路和地面-地面通信链路之间的控制回路,以提高整体文件传输效率,并使大文件能够在多个地面站主动分片和接收。利用两个独立的地面站,从UK-DMC卫星上演示了DTN的主动碎片化和被动碎片化。这些文件在位于俄亥俄州克利夫兰的格伦研究中心的一个捆绑代理处重新组装。在2009年9月30日和10月1日进行了第一次天基演示。本文详细介绍了这些实验。

Large File Transfers from Space Using Multiple Ground Terminals and Delay-Tolerant Networking
Abstract-We use Delay-Tolerant Networking (DTN) to break control loops between space-ground communication links and ground-ground communication links to increase overall file delivery efficiency, as well as to enable large files to be proactively fragmented and received across multiple ground stations. DTN proactive fragmentation and reactive fragmentation were demonstrated from the UK-DMC satellite using two independent ground stations. The files were reassembled at a bundle agent, located at Glenn Research Center in Cleveland Ohio. The first space-based demonstration of this occurred on September 30 and October 1, 2009. This paper details those experiments.
