- Node Wise details.
- Amber is working on the Pakistani Case study.
- Zafar has started taking and archiving traceroutes between Pakistani monitoring hosts on a daily bases.
- There is an explanation for differences at the end of the year. A summary of the case study will go in the ICFA report.
- Large RTTs seen between Islamabad and UETTaxila. See (https://confluence.slac.stanford.edu/display/IEPM/SEECS+to+UET+Taxila+link)20110120 SLAC SEECS meeting
. Amber making 24-30 Dec 14 plotsoverlay the daily information. She has sent new spreadsheet including all remaining metrics. Uploaded on wiki. - This is based on running long series of pings (1 week, 3 pings every 10 minutes). Amber will generate graphs to uncover the trends. Zafar has written some script and has some data, he needs to put into a format for Amber.
- Average RTT decreased since the nodes shifted to PERN network but the packet loss increased. This is usually apparent for Peshawar and Quetta. One major reason is the shift of these nodes to PERN network. Since PERN is a federated network and due to the shift of nodes, traffic on the network increased (PERN is up to its maximum utilization). Due to this though the RTTs decreased (since it is a federated environment), the packet loss increased due to congestion. Another possible reasons could be increase of nodes (especially in Peshawar region), due to which network congestion increases and thus packet loss increases.
- Amber will need to get up to speed on Linux.
- Need to get TCP configuration parameters for transmit and receive buffer lengths at end sites, and also at edge routers. Adnan talking to Zeeshan to get an update to see if he has talked to people.
- Need table of monitors vs remote sites for Pakistan. Do for a typical month, e.g. November. Amber will include this in the case study.
- Need a trend plot Jun-Dec 2010. - PROGRESS?
- Need number of hosts etc, see (https://confluence.slac.stanford.edu/display/IEPM/Pakistani+Case+Study+2010-2011). This will be added to the Pakistani case study.
- Look at NUST trends over last year, which sites have improved
- Sadia is looking at adding MOS and alpha into pingtable.
...
- Faisal is working with Yee.
- Arrows for tracerouts being implemented by Faisal.
- Working with Yee to get Lat long of perfSONAR host corrected.
- Zafar - deploy PerfSONAR nodes at SEECS. Second step is to find whether the same can be done at HEC on PERN's network. It is working, congratulations!
- Internet2 Joint Techs meeting at the end of Jan. Can Pak PerfSONAR nodes be up by then?
Possible projects
...
See \ [https://confluence.slac.stanford.edu/display/IEPM/Future+Projects\]. Zafar will talk to the students about these projects.
- Extend the NODEDETAILS data base to allow entry support for whether the host is currenty pingable.
Wiki Markup Wiki Markup - 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|display/IEPM/Make+PingER+IPV6+compliant\. 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.
