  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.
