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.
