Planned to form this as the next update, but got stuck, so reporting now.
| Testing:
Decided to integrate it directly into Freenet web UI for a number of
reasons:
- Implementing adequate and complete simulations required for
transport-layer tests is a huge standalone task that is not actually
required, so the testing will mostly be done on real-life links.
- This will need a huge amount of data to track and represent, so
need to organize it in a more comprehensive way, then pure text-logs
- Graphs (e.g. congestion window size \ time) will help to analize
the situation deeper.
| Heterogenous networks:
Currently empowering Freenet with at least Veno TCP-modification feels
a worthwhile improvement. Had anyone had any experience in the field or
just usefull-to-know stuff? The Veno implementation is simple since it only
adds Vegas backlog-tracking features to Reno algorithm that I'm going to
implement anyway, but at the same time adds a considerable boost when
operating over wi-fi (see
paper<http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.2.1469&rep=rep1&type=pdf>
).
| Traffic prioritization
This turned out to be a tough one. Just can't find a trail of the
correct direction to investigate, and own ideas seem to be too
straighforward heuristics by now. If anyone can lead to the right way -
will be grateful.
