This object is the smoothed round-trip time, in milliseconds, measured to one specific remote address of this association. Comparing SRTT across an association's multiple remote addresses reveals which path is actually faster, informing whether the SCTP-selected primary address is in fact the lowest-latency option available. A secondary address with SRTT of 15 milliseconds versus the current primary's SRTT of 80 milliseconds would suggest the primary path selection is not optimal for latency, even though it is the one currently carrying traffic.
