The minimum of the RTTs measured between Islamabad PingER hosts for each month for 2010 is seen below
|
Minimum monthly RTT measured between Islamabad region PingER Hosts from December 2009 through January 2011. Large outliers are colored yellow. Green indicates when there was a change from month to month that persisted. |
It is seen that there we were several major changes in minimum RTT between the months of June and December 2010. Most of these resulted in an increase in minimum RTT. Some of this was caused by moving connections for a site from one PERN core router to another (e.g. COMSATS), or to a campus or host physically moving from one site to another (e.g. IIU, SEECS). In general these moves resulted in an increase in minimum RTT.

The average of the minimum RTT measured between regions of Pakistan between Dec-2009 and November 2010. Spreadsheet | Various percentiles for the Inter Packet Delay Variation (IPDV or jitter) between Pakistani monitoring hosts and remote host pairs. The line shows the number of pairs with measurements contributing to the results. Spreadsheet | The blue dots are the median losses seen between all pairs of monitoring and remote hosts for each month. The error bars show the extent of the 25 and 75 percentiles. The red dots are the number of pairs contributing to the packet loss measurements. Spreadsheet |
