I think that is really old.  It is based on the Internet Draft –04, not even RFC5050.

I suggest working with some newer code.  Look at the wiki.

http://www.dtnrg.org/wiki/Code

But even the wiki has a lot of dated material.

I will not endorse one implementation over another as I really haven't done much here lately.  I will say that I have a number of small business doing research for NASA that have gravitated to IBR-DTN.  You might want to try that one.  ION also has been well maintained to date. ION supports LTP.  I do not believe IBF-DTN does.  ION also supports IPN naming, Contract Graph Routing and CBHE (Compressed Bundle Header Encoding).  If you are looking at space applications and deterministic routing, ION may be a better choice.  If you are looking a opportunistic routing, IBR-DTN may be better.

Subject: [dtn-users] BP-RI implementation test

Hi everyone,

I'm testing the BP-RI<http://masaka.cs.ohiou.edu/ocp/bundling.html> implementation. Once I got it compiled without any error I try to run it as described in the README.

However an error occurs at the start, here is the output:

root@pc-mna-78:~/BP-RI/classes# java edu.ohiou.ocp.dtn.BPServer#more configuration details below
Off-World Communication Protocols Research Group BP-RI: 1.0
 Starting BP Server:v1.0...
BPServer failed to bind to //localhost/BPServer! - Connection refused to host: localhost; nested exception is:
    java.net.ConnectException: Connection refused


Did someone already get through this one ?
Also I cannot find anything related with dynamic neighbors discovery (neither in the source code, neither in the doc, neither in the conf-file), is there any mechanism which take care of it ?
