<pre class="moz-quote-pre" wrap="">Hello birds,
I just thought I'd put together an overview of as yet unresolved
proto/babel patches and discussions to stimulate some activity :)
Toke's RTT series:
- lib/timer: Add current_time_now() function for immediate timestamp
- babel: Add support for the RTT extension
- babel: Add route metric smoothing
My route selection revamp:
- [v5] Babel: Replace internal route selection by bird's nest
- [DRAFT] Babel: Implement route daming with fixed delay (s/daming/damping/)
Toke's first two patches are ready for merging, but the third (metric
smoothing) is contested since it conflicts with my route selection patch in
its current form and if adapted it conflicts with my scalability goals for
babel instead. Possibly premature optimization admittedly ;)</pre>

<p>We generally thought that the patches were still kinda work in
progress, sorry if our non-responsivity could be interpreted as
negligence.

<pre class="moz-quote-pre" wrap="">Initially Toke was playing with the idea of exposing the smoothed metric to
route filters in a followup patch. Me and Juliusz oppose this, for
different reasons and the consensus is to not do that.
My stance is that we could choose to merge smoothing as long as we don't
expose it's implementation internals (the smoothed metric) to users. This
way we can replace it with a more performant approach later.
That being said since RTT metric is a new feature anyway I would prefer we
just go with my route damping approach, mark RTT as experimental and get
some more wider testing through a released version.</pre>

That looks like a feasible way to go. Shall we then just try to
merge these patches as they have been sent to the list?

discussion should be resolved and there are no known bugs. However I've not

<p>OK, will look at it as well. Please send me an owl, a pigeon or
another avian carrier compatible with RFC 1149 if we don't react
in a reasonable time (est. a fortnight).</p>
<p>Thank you for improving Babel implementation in BIRD. We deeply
appreciate it.<br>
