In reference to the HEC meeting to be held in the last week of May 2011, we tried to analyse the network performance for PoP node (pingerjms.pern.edu.pk) and Non PoP node (pinger.usindh.edu.pk) both at University of Sindh Jamshoro.
Metric Measurements and Results
Looking at the pingtable.pl and getting data from Pakistan to pingerjms and pakistan to usindh node, we see the following results that show the performance of both of the nodes in the first 15 days of May.
The graphs clearly show that the PoP node performance is worse than the non-PoP node. In order to get a better insight into finding the reason of this degraded performance, we looked at the traceroutes for both of the nodes from pinger.pern.edu.pk (Islamabad Pern PoP). However, the traceroutes for both of the nodes are throwing error messages.
Traceroute Results from pinger.pern.edu.pk
Following error message was received while trying to access pingerjms.pern.edu.pk (PoP Jamshoro) from pinger.pern.edu.pk (PoP Islamabad)
traceroute server busy at the moment. Please try again later.

However, while accessing usindh (non PoP Jamshoro) following error message was encountered.
Can't find address for host name pinger.usindh.edu.pk. Probably an unknown host.
