Hi,
I'm currently implementing parts of RELOAD as my bachelor thesis and
stumbled upon an ambiguity concerning answers to fragmented requests.
Section 5.2.2 states:
When a peer sends a response to a request using this routing
algorithm, it MUST construct the destination list by reversing the
order of the entries on the via list. This has the result that the
response traverses the same peers as the request traversed, except in
reverse order (symmetric routing).
However, neither this section nor section 5.7 (which covers
fragmentation) clarifies which via list should be used if the message
was fragmented. As intermediate nodes handle each fragment
independently, different fragments of the same request might take
different routes in the overlay. So for the receiving node it remains
unclear which via list should be used for the answer.
Proposal: Add the following text to section 5.2.2:
If the request was fragmented and for that had to be reassembled by the
receiving node, the via lists of the fragments may differ. The
receiving Node
SHOULD use the via list of the last fragment, as determined by the last
fragment bit; See Section 5.7
This should be a good approach, because for the last fragment's route
the probability is high to still be available.
Regards,
André
