Abstract
The objective of this project is to develop a tactical wireless network strategy that offloads TCP/IP traffic to temporary storage or alternate pathways instead of dropping packets from overflowing queues. In Phase I, we adapted DTN strategies for diverting marked packets into external queues when connectivity is lost or congestion occurs, integrated DTN methods with new OSPF methods, and developed methods for notifying TCP senders at edge nodes of potential queue overflows and to freeze TCP sends. Here we outline necessary steps for a prototype system, including OSPF modifications, DTN module modifications for HAIPE compliance and reliable operation, queue management methods to predict congestion in tactical wireless networks with variable, bursty, correlated traffic demands, new link metrics to support the DTN methods, and other system changes. We provide for system testing, including emulation testing on a government scenario with a government waveform using BBN's K-Node emulation system. SSCI will be assisted in this effort by BBN Technologies, whose expertise in internet technologies and the WNW waveform, combined with SSCI's successful experience in developing Phase III systems in Automatic Missile Routing (CMARS), image navigation, and unmanned, autonomous, undersea vehicles will help ensure successful prototype development in Phase II and a successful Phase III transition.
