I would encourage allowing minimum RTO values down to 5ms, if the ACK policy in the receiver makes this feasible. Our experience is that in datacenter environments it can be advantageous to allow timer-based loss recoveries using timeout values as low as 5ms, e.g.: https://www.ietf.org/proceedings/97/slides/slides-97-tcpm-tcp-options-for-low-latency-00.pdf https://tools.ietf.org/html/draft-wang-tcpm-low-latency-opt-00 cheers, neal
