- Les has his Pakistan visa and airline tickets. There are problems getting authorization from DoE. How do things look following the Lahore American consulate incident?
- The draft letters of invitation for Sadia and Amber are with SLAC's international services. I have given expected dates of arrival, phone # and email addresses to SLAC international office.
- Sadia, Amber and Bilal have their SLAC computer and Wiki accounts. Amber had a problem with her Windows password, is it fixed?
- Zafar received his DS-2019 on Dec 10 (Fri). Applied for visa on Dec 13 (Mon). Interview date was Jan 3, it has been delayed to 24 Jan. Update.
Pakistani case study - Zafar, Anjum
- Nodes wise details
- Amber is working on the Pakistani Case studyPakkistani case study is done for the moment.
- A summary of the case study is in the ICFA report.
- UETTaxila Zafar
- Zafar has started taking and archiving traceroutes between Pakistani monitoring hosts on a daily bases.
- Amber has analyzed, apart from high congestion it is hard to get patterns of use. She will update the report
- Amber will need to get up to speed on Linux.
- Look at NUST trends over last year, which sites have improved
- Sadia is looking at adding MOS and alpha into pingtable/analyze-xxx. Progress
ICFA Report
- The ICFA report has been submitted - Zafar
- Zafar is working on a case study for Egypt. See https://confluence.slac.stanford.edu/display/IEPM/Egypt+shuts+down+their+Internet. It is awaiting the restoral of services.
PingER
- The traceroute server and ping_data.pl have been installed and working in Sarawak.
- The traceroute/ping server needs to be added to TULIP.
- We are working on getting pinger2.pl working. The pinger.xml page needs to be fixed
- PingER archive site: Ghulam and Farhan couldn't discuss database architecture with Umar Kalim. They have however created two ERDs. One is a simple design (relatively inefficient) and another is a complex design (relatively efficient though it might introduce some redundancy). They have created MySQL databases following both ERDs and will start work on stress testing it as soon as they are free from exams. Zafar has discussed stress testing with them already and they have a fair idea of what to do.
...
- Extend the NODEDETAILS data base to allow entry support for whether the host is currenty pingable.
Wiki Markup Extend Checkdata to provide emails automatically, see \[https://confluence.slac.stanford.edu/display/IEPM/Extend+checkdata+to+make+it+more+useful\]. Many of the ideas in the script node-contacts.pl are a step in this direction.
Wiki Markup Add *MOS and alpha to pingtable.p{*}l see \[https://confluence.slac.stanford.edu/display/IEPM/Add+Mean+Opinion+Score+%28MOS%29+to+pingtable.pl+metrics\] Sadia will start work on it when done with HEC report, writing thesis. Sadia and Zafar are looking at this. It requires cahnges to pingtable.pl and analyzs*.pl scripts.- Improve the PingER2 installation procedures to make it more robust. This might be something for the person(s) in Pakistan who are responsible for installing PingER2 at the Pakistani monitoring sites. They probably have found where the failures occurs. Also look at the FAQ, and ping_data.pl which has been improved to assist in debugging, could it be further improved (e.g. provide access to the httpd.conf file so one can see if it properly configured)? There are 2 students working on the PingER archive. *Is this something they could work on?*
- Fix PingER archiving/analysis package to be IPv6 conformant. Will build a proposal for an IPv6 testbed. They will try various transition techniques. A proposal has been prepared and that has been submitted to PTA. Adnan is a co PI. It is being evaluated today. A small testbed has been established in SEECS and the plan to shift some of the network to IPv6. Bilal is part of 3 students involved with PingER and they will be involved with IPv6. They are porting the PingER archive site site to using a database. They have redeveloped the archive site using Umar's documentation. They have set up a small test archive site. They have gathering, archiving, analysis. They will design a new database. They will also try a port of PingER to IPv6.
- Look at RRD event detection based on thresholds and how to extend, maybe adding plateau algorithm. Umar's algorithm did not work in a predictable manner.
- Provide near realtime plots of current pinger data using getdata_all.pl
