  2. NASA DTN Space Readiness Project • Review existing DTN Protocols and Implementations for Space Systems • Bundle Protocol • Licklider Transmission protocol • Develop System Architectures for Space Systems • High Delay Links • Deterministic, Periodic Contact • Extremely Limited Bandwidth (low power, low opportunity, sparse mesh) • Design and Prototype Critical Support Applications • Network Management • Security • Routing Image credit: NASA/JPL With the increasing number of planned missions, future space networks will require autonomous, network-centric, packet-switched networks to achieve mission goals

  3. Roadmap (Unreadable)

  4. Infrastructure Themes • Link Simulation • API for defining complex link characteristics • Pluggable link models • Faster than simulation-time message delivery • Link Administration • Backchannels to collect link information for post-experiment analysis • Visualization of link state • Ability to change links during the experiment • Change link endpoints (Orbiters) • Change link bandwidth and bit-error (elevation angles) • Change link delays (orbitology) • Focus on Node Emulation • Heterogeneous hardware platforms (Intel, PowerPC, embedded) • Instrumented node analysis (CPU, RAM, Network usage) • No bias inserted from virtual machines, if desired.
