Flight Systems Maturing the JPL ION DTN implementation to common NASA-wide implementation Include in Goddard core Flight Executive Use common codebase across APL, Goddard, JPL, JSC missions More from Jane when she talks about the ION Working Group 28 October 2009

Demonstration and Validation DTN supporting BioServe on ISS Operating 24x7 Getting operational experience 2nd on-orbit DTN node due to become operational March 2010 DTN Experimental Network (DEN) Multi-center testbed Supports experimentation and validation of new capabilities Performance in errored / delayed environment Bundle Authentication Blocks (hop-by-hop security) Operations Scenarios Lunar Habitat Scenario: Streaming video over DTN Tunnel (tested between JPL and JSC) 28 October 2009

Demonstration and Validation DINET-I Flight Demonstration Report available DINET-II Flight Demonstration Operations in mid-November 2009 CFDP / DTN / LTP implementation DTN capabilities in TDRSS DTN at TDRSS Ground Station DTN over LTP over Encap over AOS Planning demo at SpaceOps 2010 28 October 2009

Demonstration and Validation: Lunar Surface Motion Imagery Scenario

Protocol Engineering Network Management Routing Security Have been working ‘SMTP-like’ approach: local monitoring and control coupled to DTN gateway for remote communications Basic MIB under review Routing Have been experimenting with Contact Graph Routing; used on DINET-I and –II Implemented in ION and soon in DTN2 Security Bundle Authentication Block implementation for ION, full Bundle Security Protocol implementation for DTN-2 Naming and Addressing ‘ipn’ scheme consistent with compressed bundle header encoding ipn://X.Y where X and Y are self-delimiting numerical values (auto-scaled integers) for node number (interface) and service number (port) 28 October 2009

Specification and Standardization Green Book continually revised Talk Thursday about additional requirements and operational scenarios Want to come to consensus on a schedule for completion Concept papers for protocol specifications distributed in July / August Step 1: Slap a service specification on the existing specifications Step 2: Revise specifications / service specifications in response to requirements, operational scenarios from October Green Book inputs Step 3: Testing and experimentation by agencies Step 4: Submit for Red-1 Status 28 October 2009
