Military Applications
• 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.

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.

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.
