Looking at the pingtable.pl following trend was observed for various metrics.

 

High RTT values were observed previously with frequent fluctuations however, RTT values lowered and smoothed out later on. This fact is also supported by the IPDV values before and after the network change as you can see in the graph above. An increment in Throughput values is also evident with the reduction in Packet Loss. All these are results of increased capacity of the network.

This can also be shown in numeric figures by looking at the following table obtained by averaging the pingtable.pl values. The Average RTT reduced by a factor of 1.91, packet loss by a factor of 3, throughput increased 3.14 times and IPDV reduced by a factor of 38.

...

Due to some unavoidable reasons, no smokeping graphs could be generated so far. Once we resolve the issue, we'll show smokeping graphs and traceroutes to support the improvement in network performance. 

Traceroute were taken from PERN POP Islamabad to Uettaxila showing the RTT at each hop.

Code Block

Executing exec(traceroute, -m 30 -q 3 -f 3, 121.52.150.164, 140)
traceroute to 121.52.150.164 (121.52.150.164), 30 hops max, 140 byte packets

 8   (121.52.150.164)  46.431 ms !X  46.175 ms !X  46.519 ms !X

It is observed that the route goes through the 3 interfaces named rwp44.pie.net.pk. Delay to reach rwp44.pie.net.pk is much longer which results in increased RTT for uettaxila. However, from there it takes only 13.8 ms to reach uettaxila.

Suggestions from improvement:

...

Reduced average RTT is a consequence of increased link capacity.

Unresolved Issue:

  • Since Friday 5/13/11, I am unable to load SEECS pingtable and the smokeping graphs from SEECS pingtable. I need them for analysis. Can someone get this resolved so that I can make report as soon as possible.
