15 MR Assists with Rapid Deployment of Networks. MR enables mobile sub-networks to dynamically attach and reattach to multiple points on a network. MR “Set & Forget” Technology - Engineering/optimization is done prior to deployment. Military Applications

16 Military Applications AWACS UAV Intelligence Control Center Battle Group Command Center (BGCC) Home-Agent deployed in BGCC Foreign-Agent deployed in UAV Foreign-Agent deployed in Tracked Command Post Carrier. Unit deployed in vicinity of the battlefield. Tactical data forwarded from surveillance satellites to the BGCC. Communications link between BGCC and the Field Command Post Mobile-Router deployed in Armored Field Unit. Secondary communications link utilized due to lost LOS of primary. Non-preferred-path becomes preferred-path Preferred-path Non-preferred-path In case of communications loss of preferred-path Mobile-Router deployed in Armored Field Unit.

17 Future Developments Multicast traffic to Mobile-Router. Routers behind Mobile-Router. Mobile-Router behind Mobile-Router. Secondary HA configuration. Mobile-Router’s registration over Asymmetrical Links.

19 Summary MR “Set & Forget” Technology - Engineering/optimization is done prior to deployment. MR assists with rapid deployment of networks. MR enables mobile sub-networks to dynamically attach and reattach to multiple points on a network. Performs well in long delay environments Redundancy can be engineered into a Mobile-Router network design.
