NASA DTN Space Readiness Project Request for Experimental Infrastructure Ed Birrane

NASA DTN Space Readiness Project 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 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

Roadmap (Unreadable)

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.
