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)
