a7c8be4d69 base backpressure decisions on queue size in bytes, instead of packet counts 2018-07-05 23:07:01 -05:00
Arceliar
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

166d25619d Attempt to support NetBSD 
This code actually consolidates a lot of the BSD code together, and even setting the interface MTU with SIOCSIFMTU seems to work fine.

What doesn't work though is setting the interface address using SIOCSIFADDR_IN6, which I attempted to plagiarise from the Darwin code.

As a fallback, ifconfig is used, which solves the problem enough to get it working.
