Hello!
My name is João Loureiro and I'm a MSc student at University of Porto (Portugal) & INESC-TEC (a research institute).
In my master thesis, I'm performing some tests using the IBR-DTN tool "dtnstream" and 3 nodes, where the first node (sender) only reaches the third (final destination) through the "middle" node.
The problem I'm facing is the following: I want the destination (where the video/audio stream is being reproduced and piped into VLC player) to ignore lost bundles/chunks, i.e., If I receive at this node, for example, the chunks with the seq. nrs. 0,1 and 3, I want to have a continuous video streaming, ignoring the packet with seq. nr. 2, and passing from 1 to 3 instantaneously or with a specified timeout.
I've read the documentation and this paper: https://doi.org/10.1145/2030652.2030673, but, in my understanding, and following the dozens of tests I've already performed, currently dtnstream keeps waiting for the right sequence number instead of keep going with the last received one. I just wanted to confirm that is truly what is happening and, if it is, if there's some simple tips for modifying the code in order to obtain this behavior (I have already tried several modifications but with no success...).
Thanks a lot for your help, in advance!
