DTN Interoperation Demonstration: End-to-End Transmission Testing

Testing interoperation of DTN implementations demonstrating end-to-end topology and features such as payload sizes, message formats, and status reports across multiple links without custody transfer. Includes performance, recovery, and custodial retransmission tests.

  1. DTN Interoperation Tests IETF, San Diego 8 November 2006

  2. Participants • Kevin Webb – GA Tech • Jon Olson – GA Tech • Jeff Ward – BBN • Joerg Ott – TKK • Keith Scott – MITRE • Mike Demmer – UCB • Scott Burleigh – JPL • Kevin Fall – Intel

  3. Implementations *Descended from DTN2.

  4. Interoperation Demonstrated

  5. End-to-end topology Demmer-mac .11, RI tcp BBN, java .31, RI ext CL udp Demmer-pc .12 udp Pocket, C# .63 udp jpl1 .23, ION mitre2 .52, RI 770 .42, RI on Nokia770 War, C# .61 udp tcp udp udp Charon, C# .62, GA Tech mitre .51, RI ext Rtr 9300, C++ .41, Symbian tcp Status reports direct to demmer-mac Destination dtn://9300.dtn/send “Hey, these status reports are kina useful.”

  6. Features tested • End-to-end transmission across 9 links (10 nodes in total). • Without custody transfer • With custody transfer • Payload sizes varying from 6 bytes to 1545 bytes. • Raw text messages. • Email-format messages destined for Symbian phone. • All status reports generated and parsed. • Report-to different from source endpoint. • Partial test of TTL expiration.

  7. Possible tests on Friday • Performance: end-to-end throughput. • Recovery from disruption. • Custodial retransmission. • Multi-path forwarding.
