That's right, there's no one-size-fits-all solution. That's why I'm
in favor of keeping a reasonably conservative default (say 1s to 3s,
so we don't break the Internets) and giving people a knob to adjust it
to whatever makes sense for them.
Looking through the kernel, I see that SCTP already has knobs for
this: sctp_rto_initial, sctp_rto_min, sctp_rto_max. You can even
control the constants used to update rttvar and srtt: sctp_rto_alpha,
sctp_rto_beta
