Previous Hop Information for IBR-DTN
Hello, I am currently implementing a newer version of the EBR network coding router in IBR-DTN and one of the requirements is to keep track of when and from whom I got my last bundles from. Does IBR-DTN keep track of the previous hops for each of the bundles? Do forwarded bundles update with new information in intermediate nodes? Thank you.

Hi Carson.
IBR-DTN tries to figure out the previous hop and logs this information. The previous hop block is not implemented yet, but planned for future releases.
We do not track the whole way of bundles by adding each hop to the bundle.
Kind regards, Johannes

Johannes, Thank you for the response. Where is the previous hop information logged? I'm not worried about all of the previous hops, just the most recent one for a specific bundle. Thank you again.

Hi Carson,
you can see this information logged in the standard log output of the daemon. It is attached to the BundleReceivedEvent like this.
