Delay and Disruption Tolerance (DTN)
• Variable interplanetary distances
• Planetary motion
• Terrestrial tactical jamming, radio shadow, loss
• Bundle Protocol Features
• Memory in the network (“custody bundle forwarding”)
• Multiple paths and muiticast
• Forward error correction
• Network Management in DTN environments
• Ping and SNMP may not be your “friends”
• Strong authentication, replay resistance
• Delayed binding of destination(s)
