3. 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

4. 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

5. 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

6. Demonstration and Validation: Lunar Surface Motion Imagery Scenario

7. 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

8. 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
