Hello,

I am working on DTN Routing for my study. I am using DTN2 code=A0to test= =A0DTN routing algorithms. I want to test a scenario of "Loop Back&quo= t;. The system setup is like, I have 2 Nodes (A & B), I want to send an= d receive a packet in A routed Via B. Currently I am using Static route=A0t= ype in the configuration file and=A0link and route=A0as,

=A0

Node A : (dtn://ubuntu10.dtn)

route set type static

link add link_dtn1=A0<IP_Addrs> ONDEMAND tcp

route add dtn://ubuntu1210.dtn/* link_dtn1


Node B:(dtn://ubuntu1210.dtn)

link add link_dtn2=A0<IP_Addrs> ONDEMAND tcp

route add dtn://ubuntu10.dtn/* link_dtn2

=A0

Send Message using.,

./dtnsend -s=A0dtn://ubuntu10.dtn/a =A0-d dtn://ubuntu10.dtn/b=A0 -t m -= p "message loop"

Can any one please help me ?

Hello Somreeta,

The ION node is including a Previous Hop Insertio= n Block (RFC-6259  - Block type 0x05) which the DTN2 node is having a = problem parsing.

 

somreeta dtn% [1411747528.640888 /dtn/bundle/protocol er= ror] error parsing previous hop eid 'dtn://somreetadtn.dtn

[1411747528.640922 /dtn/cl/tcp/conn/0x7f7268000940 error= ] protocol error parsing bundle data segment

 

The EID looks acceptable to me (dtn://somreetadtn= .dtn). You might try turning on debug level logging to see if it provides m= ore info. You may find a problem down in the oasys::URI parsing methods.

 

Good luck,

DZ
