Hello Mr. Tavares,

actually the best way would be to tell me the version code of the daemon like this.
$ dtnd --version
IBR-DTN version: 0.9.0 (build b3e6377)

Assuming you are using the latest version, I need some more details about your tests. How does your script work. There are a lot of approaches to bring an interface "up" and "down". So what do you do exactly?

What might happen is that your disconnection is too short for TCP to fail completely. Instead TCP would ran into several timeouts but never disrupt completely. What happens is you longer your disconnect interval to 120 seconds or some minutes?

Kind regards,
Johannes Morgenroth

Hello Mr Morgenro

The version I downloaded was from repository from yesterday : 

Tue, 11 Jun 2013 10:47:40 +0100 (11:47 +0200)

Is this information I should send?

I was working was a old version of repository and I noticed that issue and then I tried with the latest version of repository and the behaviour seemed to be the same. Any ideias of what might be?

Best regards

Good afternoon.

After several tests using ibrdtn from repository I noticed this following issue:

I have two nodes in my scenario: A and B.

A has a bundle of 77 MB to send to B.

I have a script running on node A that puts the connection interface of that node up for 10 seconds and down for 20 seconds.

In the beginning some data is transferred from A to B during those 10 seconds.

In lots of the "10 seconds" intervals there is no transfer of data.

I even putted the interface after some intervals up all the time and no data was transferred for lots of time.

Is this a problem someone noticed?

Can anyone give a little help to understand the problem.

Thank you

Best regards

Bruno Tavares
