Once you start simulating the network failure, how long do you wait?
If you have not changed rto_max and path_max_retrans, you can end up
waiting quite a while for the full path switchover. This will also
severely slow down your retransmissions...
I'm waiting several minutes, and I'm using setsockopt() to set the
timeouts fairly low:
srto_initial = 1000ms
srto_min = 200ms
srto_max = 1400ms
spp_pathmaxrxt = 2
spp_hbinterval = 1000ms
Ok, thanks for the info. Two more questions:
1. What did you set the sinfo_timetolive to?
2. What specific netfilter rule to do use to simulate network outage?
I was using '-t filter -A INPUT -i eth0 -p sctp -j DROP'
Just trying to get more info to simulate this. My prior attempts
recovered quickly with my patch.
Thanks

The network's round trip time (indicated by ping) is on the order of
<0.25ms.
