- See http://pinger.seecs.edu.pk/cgi-bin/traceroutearchive.cgi
- Autotrace.pl is now getting the nodes name from NODEDETAILS added by sadia.
- Assuming user knows when the change has occured, it is given a flexibilty to see traceroutes difference from three dates . This has been added by sadia
- some improvements needed:
- Difference using only IP's and name in traceroute currently sadia is working on it done.
- Enable selection of days bracketing an RTT step change to see if there was a traceroute change then.
- Provide better default hosts (e/g/ PERN and SEECS) done.
- Extend to traceroutes from SLAC.

- The new schema of PingER which is close to perfsonar is designed such that it stores raw data as well as analyzed data in the same table. Previous architecture of PingER first collects the data into files or table, then analyze this data and store results in another file or table. And then these hourly results are used for calculating daily and monthly results. The mechanism is as follows:*# At archive site, as the data is downloading from monitoring sites line by line, the new script does not store this data in to file on table but it uses each line's data (Basically one line contains sequence numbers, RTTs, packet size, packets sent and recieved, time and nodes information) and calculate different metrics by using data of this line.
- Stores these calculated metrics into arrays or keys and moves to the next line and same procedure goes again and again for every line.
- When all lines are processed we calculate or aggregate results on hourly basis and store all related raw data and analyzed data for this hour in one row.
- Daily and monthly analysis scripts which are running separately use this data (that is calculated previously) and again store results in same table but this time no raw data is stored in respective rows which contains daily and monthly data.

- Analysis scripts to add Mean Opinion Score and Alpha, some things need to be correctly configured. It has been deployed at [[http://pinger.seecs.edu.pk/cgi-bin/pingtable.pl|http://pinger.seecs.edu.pk/cgi-bin/pingtable.pl]|http://pinger.seecs.edu.pk/cgi-bin/pingtable.pl] for testing.
- Alpha and MOS to be implemented at SLAC site. Sadia will be doing this with the help of Zafar.Currently Ghulam and Farhan are working on synchronizing the SLAC and SEECS scripts.
TULIP
- PlanetLab landmarks are working. The problem was in timeouts. Fixed by Zafar.
- TULIP is still slow. The tiering into 0 and 1 done by reflex.cgi reduced times by a factor of 2.
- Enabling/disabling of hosts appears to be working. However, the disabling of hosts has not been turned back on in th daily cronjob. Les will look at again this weekend, and see whether to turn back on.
- Reflex.cgi is ready for production use. Bilal should convert to using it. Reading documentation would bring him in good shape.
- Bilal would be working on adding clients.
