654407dc6d close long-dead connections in link.go instead of in switch.go, this is important in case a connection opens but never bothers to send even one switch message 2019-02-24 13:24:55 -06:00

042adb0516 make sure the only place traffic is ever dropped is in the switch. this currently disables the dedicated crypto workers 2019-02-23 00:07:00 -06:00

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

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

b63b534fa7 drop packets that have been queued for longer than some timeout (currently 25ms) instead of using fixed length queues 2018-06-25 18:12:18 -05:00

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
