Jitter (Inter Packet  Delay Variation - IPDV)

We might expect the network performance to hosts that are in a war zone may be degraded and show up as more variability on the RRTs.A sensitive measure of variability of the RTTs is the Jitter between adjacent measurements. We use a derivation of the Inter Packet Delay Variation (IPDV) to estimate the Jitter from the Ping measurements (see https://www.slac.stanford.edu/comp/net/wan-mon/tutorial.html). In addition we characterize the proximity of the war to a host in Ukraine by its proximity defined  as:

We then plot the IPDV and proximity for each Ukrainian host monitored and look at the correlation between the IPDV and proximity

There is a small positive correlation between the proximity and IPDV.
