Neil Alexander	3f4295f8cd	Only split queues based on port number for TCP/UDP/SCTP, rely only on protocol number for other protos to prevent issues with IPIP, GRE, etc	2018-07-22 12:00:40 +01:00
Arceliar	9cbcaf39ac	Use coords for queue stream IDs in the switch, and append protocol/port information to coords when sending, to designate different streams	2018-07-21 18:59:29 -05:00
Arceliar	5dfa01a0e8	periodically clean up timed-out sessions and old signatures, instead of trying to do it when creating new sessions or adding new signatures	2018-06-21 20:31:30 -05:00
Arceliar	f7a7f601a0	cleanup old ugly session MTU code that only mattered with lossy UDP fragments	2018-06-14 08:38:43 -05:00

Arceliar	63b55cda62	Mostly working PMTU discovery when going over UDP links	2018-02-25 20:24:36 -06:00
Arceliar	bb3ae8b39b	temporarily limit PMTU to 2048, as a workaround to some pathelogical behavior where a TCP stream carried over a UDP peer can throttle down to 0 in the presence of significant packet loss	2018-02-23 12:46:22 -06:00

Arceliar	75965b6da4	Switch connAddr (udp map key) from string to a struct that allocates less. Reduce some other allocations. Use larger channel buffers to reduce backpressure from runtime jitter.	2018-01-13 07:26:26 -06:00
