- An extensive end-to-end network monitoring infrastructure has been set up for PERN connected universities in Pakistan. Over the last year its has grown from 30 monitoring-remote node pairs to over 500 covering most of the major universities in the main regions of Pakistan.
- At some sites, installation and start up of monitoring hosts was delayed by weak local support.
- There is a great deal of variability in the reliability (unreachability) of hosts. Much of this is due to loss of power. An effort needs to be made to understand and improve power reliability and the provision of backup for several sites.
- Given the measured MOS, VoIP tools such as Skype should work well between PERN connected hosts.
- The low values of alpha lead to the conclusion that there may be a lot of indirect routing in the Islamabad region. Further work with PERN is required to see if this can be remedied.
- The poor throughput performance to Quetta is understandable. More work need to be done to understand why Karachi looks so bad.

We acknowledge the patient and persistent efforts by Zeeshan and Fahad Gilani of NUST to spearhead the installations of PingER at the various sites. Anjum ? Naveed and Adnan Kianai led the efforts at NUST. The PingER map tool was developed by Faisal Zahid while at SLAC and turned out to be extremely effective in drilling down and understanding the connections. The Smokeping tool was developed by Fahad Satti while at SLAC. We also acknowledge the continued encouragement and support from Arshad Ali of NUST.
