We will try this on Monday and report back if everything works. Is there any way (except for patching the code) to specify the retry_interval in milliseconds other then in seconds?

So all of us here, who are familiar with DTN2 code can work easily with our BP-RI.=20 The BP-RI supports just LTP as a convergence layer, currently, interfacing = with our LTP-RI implementation in Java. LTP-RI has also been updated getting some minor designs and bug-fixes along the way.
