Next we look in more detail at the route from Daffodil to S. Asia Since the traceroute server at Daffodil is not working instead we look at the reverse routes to Daffodil from Pakistan and Sri Lanka. The route from Pakistan to Daffodil actually goes from Pakistan to Europe and then back to Singapore and Bangladesh hence accounting for the low value of Directivity. A similar result is seen for the route from Pakisan to Duet..

The distance as crow flies between pinger.daffodilvarsity.edu.bd and www.duet.ac.bd = 189.2 km. or a minimum RTT (as constrained by speed of light in fibre) = 1.892. the average minimum RTT from Daffodil to Duet is 2.55msec. This corresponds to a Directivity of 0.74, i.e. the route is pretty direct. The spreadsheet of the data from which the plots below were derived is here. The variability of the RTTs is much greater than that between hosts at the Daffodil site . (first plot). Thus most of the variability is attributed to the route between Daffodil and Duet and possibly the host at Duet.
