- 27 more hosts are yet to be deployed - is this current?, currently at ~ 37 will go to 60.
- Sadia Updated the MOS reports for PERN-PERN, PERN to non-PERN, see here. This is suffiicinet forr Anjum. Anjum is waiting tio hera from Anwar to schedule.
- To assist in identifying PERN nodes Sadia has updated the affinity groups and procedures and add a PERN group and a PERN-POP group. This is documented at http://www-dev.slac.stanford.edu/cgi-wrap/scriptdoc.pl?name=create-group.pl
- pingerjms.pern.edu.pk is a node deployed at Jamshoro university and it will remain UP 24 hours because it has a backup power supply as it is POP. However, another node pinger.usindh.edu.pk is in the network of unversity (Non-POP) and is behaving how a networkcommonly behaves in that region. Compare the measurements of both the nodes and analyze. Check if all metrics are working and also check if avaialbility is better. Amber will be doing this. Done. See Comparison of PoP (pingerjms.pern.edu.pk) and Non-PoP (pinger.usindh.edu.pk). We need to verify the tracreoutes and min RTT.
- Has anyone at PERN been approached about giving someone from HEC the responsibility for ongoing support. Concern will be that once the nodes are deployed, we will have all the latest patches but since these nodes will be on internal network and it could be a potential security hazard once security is breached. Umar suggests that we should get this in writing from HEC that they'll be responsible for these nodes on their POPs. This is probably in the noise compared to the HEC problem. Anjum will send email to Anwar Amjad or one of his lieutenants to ID someone to manage the nodes. No word. Managing of node is responsibility of NUST after project is closed.
- Putting monitoring hosts on UPS. Anjum is following on this with PERN. Just the POP nodes.
- Dr. Anjum and his team at SEECS will be presenting the Pinger performance in reference to PERN and POPs to HEC (Anwar Amjad and his team). Sadia and Amber will be helping him. Dr. Les would be providing input on what should be included in presentation that could be of interest to HEC. Few things that he would like we should present are: MOS analysis as discussed , UET Taxila analysis, more concrete findings in terms of high RTT for various nodes within Pakistan, separate analysis of PoP nodes. How did it go? Is more needed?

We have given up and Disabled Falcon at the University of New South Wales? _UPDATE: Dr. _Anjum says we can have a node at Newzealand, one in OaklandAuckland. How is this going? The other node can be in Malaysia in the state of Johar near singaporein Malaysia. UNS node was managed by a student who has graduated and we can't get it better for now.

- Choose hosts without worrying about the date.
- Latest successful traceroute shown from A to B (left hand box) and B to A (right hand box).
- Changes (from A to B and B to A) also shown since a past successful traceroute (diff between the latest traceroute and the one half way since inception time (i.e. since April 1, 2011).
- Some sites might not be working due to PERN proxy policy. Sites that are on PERN network do not allow connections outside the 111.68.y.z IP domain. Some are just simply unavailable.
- Traceroute.pl has been updated at Pakistani monitoring hosts.
- Anjum has seen anomalies, will send output and we will fix.

- PerfSONAR at SEECS: Problems were fixed. NTP servers were causing considerable clock delay. Added close-by Stratum 1 NTP servers to solve the problem. Nodes were updated to PerfSONAR version 3.2 (Fedora distro). Nodes however are offline since they were disrupting normal traffic. We are waiting for 10 Mbps dedicated connection to switch the nodes back on. We have a 1 Mbps link for PerfSONAR (on temporary purposes). NUST is purchasing a 2 Mbps dedicated link from WorldCall. No progress yet .. routing issues are showing live IPs as inaccessible.
- PERN will deploy perfSONAR at HEC/Quetta. Someone is working on this. The university is close by HEC/Quetta. Hope in 4 weeks to have PingER monitoring node in 4 universities in the Quetta region.
- No Updates as Dr. Anjum were not in Pakistan for past couple of weeks. He will talk to Wahab and Imran Ashraf and get the update. Headquarters did not allow this but SEECS have some direct IP so we need to find if we can get a direct IP for this purpose, then we can deploy perfsonar.
- Anjum will let Zafar know the IP addresses
PerfSONAR (USA)
- Zafar is working on making SNMP-MA remote-connection-capable. It will provide the ability to read RRDs over the network instead of having the RRDs on the same machine as the RRD client. Code is working and testing is complete. Yee wants me to work on a few changes from architectural perspective. Done. Committed to Internet2 svn (go under zafar at http://anonsvn.internet2.edu/svn/perfSONAR-PS/branches/ to view).
