Suppose that TCP$\text{'}$s current estimated values for the round trip time $($estimatedRTT$)$ and deviation in the RTT $($DevRTT$)$ are $360$ msec and $17$ msec, respectively $($see Section $3\mathrm{.}5\mathrm{.}3$ for a discussion of these variables$).$ Suppose that the next three measured values of the RTT are $390$ msec, $350$ msec, and $270$ msec respectively.
