Arceliar	21cecf4630	consistently prioritize which peer to forward to instead of letting it be partly random	2019-02-09 17:44:25 -06:00
Arceliar	74ac535d55	slightly faster switch logic, should be easier to have a useful tie-breaker for peers that are equally close to the destination via the tree metric	2019-02-08 19:46:11 -06:00
Arceliar	5ddf84f329	remove peers completely after a long switch timeout, this could use some improvement later	2019-02-03 15:22:14 -06:00

Arceliar	3d4b49b693	reset the switch speed info for a peer whenever it changes coords, instead of only if they're a parent and change coords. Also, make sure packets in the sim preserve order when sending, to avoid races when testing	2018-12-03 19:21:23 -06:00

Arceliar	7695a3fcbf	try using a simpler FIFO order for each backpressure buffer, since there are other mechanisms to penalize the flooding node, leads to better TCP throughput without affecting traffic between other nodes (does affect traffic in the same session, but there's hypothetically workarounds to that)	2018-06-24 20:20:07 -05:00

Arceliar	9c028e1d0d	switch to a separate queue per stream of traffic, FIXME for some reason this makes distance calculations more expensive in handleIdle?	2018-06-24 17:39:43 -05:00
