SLAC SEECS Status report June 20th 2012

Attendees

Present: Umar, Asad, Les, Sadia.
Anjum, Zafar, Ghulam and Amber were not present

General

Asad will be joining us from now on. He is finishing his course work in a couple of months. Les submitted Next step is to fill out the forms for a computer account.He has an account now need to get him Confluence access.

Maggie was not working due to no disk space. Anjum gave the go ahead to clean /tmp/. Joun was away he will see if he can get it going again (5/29/2012). No update.

Umar talked to Anjum. Lack of funds is a problem. NUST will not continue funding. HEC funding has run out. If we havre graduate students then they need funding. Maybe something can be done with undergraduates. Meanwhile we should try and document the state of archiving. When Arshad arrives, this funding for the project and his plans should be a topic of discussion

Zafar will be in Pakistan until August. At that time he will be going to Sweden for a year for his Erasmus Mundus scholarship MS. Any contribution we get from Sadia and Zafar will be voluntary. Sadia is joining Bahria university in Islamabad as a lecturer in telecom. If Anjum can get a student, Sadia and Zafar can work with/guide him/her

PingER

Les has been invited to Nairobi, Kenya for the November meeting of eGYAfrica. He will be updating the case study on Africa to use as part of the talk.

The PingER monitoring host at Kuching, Sarawak in Eastern Malaysia is taking data again. Les will have a Skype meeting with Kuching on Thursday 6/21/2012.

HEC Report - Anjum, Amber and Imdad

Amber is working on this report. The basic structure is the same as was of the last 6 monthly report. She will be sharing the report in a few days. Amber was unable to attend the meeting so there was no update.

Pakistani Hosts

There are some Pakistani nodes that are recorded as working from SEECS while they are not working from SLAC. This mismatch was recorded by Amber and Joun. Amber and Joun will get together and see if the problem still exists or not. Les will send a reminder to Joun at joun.muhammad@seecs.edu.pk. This was done the following day.

  • Les looked at which Pakistani monitoring hosts SLAC is unable to gather data from since the start of May. They are as follows:
    • hu.seecs.edu.pk aka PK.HU.EDU.N2 does not appear as a monitoring host in SEECS pingtable.pl. Also SEECS pingtable.pl has no data this month from AIOU to hu.seecs
    • lse.seecs.edu.pk aka PK.LSE.EDU.N3 does not appear as a monitoring host in SEECS pingtable.pl. Also SEECS pingtable.pl has no data this month from AIOU to lse
    • pinger-itc.pu.edu.pk aka PK.PU.EDU.N2 does not appear in the SEECS pingtable.pl as a monitoring host
    • pinger.giki.edu.pk aka PK.GIKI.EDU.N1 does not appear as a monitoring host in SEECS pingtable.pl
    • pinger.uaar.edu.pk aka PK.UAAR.EDU.N1 does not appear as a monitoring host in SEECS pingtable.pl
    • pinger.ustb.edu.pk aka PK.USTB.EDU.N2 does not appear as a monitoring host in SEECS pingtable.pl
    • sbkwu.seecs.edu.pk aka PK.SBKWU.SEECS.EDU does not appear as a monitoring host in SEECS pingtable.pl
  • Should they be designated as Monitoring hosts?
  • Amber reports: Looking at this weeks status report on wiki, the list of the nodes which are not monitoring nodes in SEECS pingtable but are monitoring nodes at SLAC can be due to the fact that these nodes are the usual problematic nodes since months. It might be possible that SEECS team (who manage SEECS pingtable) have made these nodes as remote nodes to avoid hassle. However, she will confirm this from Kashif tomorrow and will update you on this. If this turns out to be true, she will change these nodes to remote nodes in SLAC pingtable as well.

FSBD  POP has high unreachability values, which is not acceptable. They are looking into it. Backhaul network is currently leased from PTCL however in 3-4 months they will replace it with their own network. There would be no commercial traffic on it. As a result it is expected that RTT and losses will improve drastically. So next 6 months are important for observing the network performance.

TULIP - Bilal

Asia as a whole looks bad, Pakistan looks good (i.e. CBG is way better than GeoIP). 

Sadia has sent instructions to Raja on how the measurements were made. He will need an account at SEECS and SLAC. He has the codes etc. Raja has been going through the documentation sent to him by Les. He should start trying to set up and run the code and make measurements. This will provide real life exposure to understanding the tool and how to analyse the data. A next step would be to look at alpha values and how they change from region to region. While testing etc. hee needs to communicate his experiences, difficulties etc. Also spend some time looking at what has been done in CBG & since. Google's geo location has taken off this could be interesting and understand their algorithms.

Other things to look at may include: some correlation of accuracy versus number/density of landmarks in region.

Another interesting study would be whether using different alphas (in distance[km]=alpha*min_RTT[ms]*100[km/ms]) based on the alphas found in PingER for the various regions (see for examplehttp://www-wanmon.slac.stanford.edu/cgi-wrap/pingtable.pl?file=alpha&by=by-node&size=100&tick=daily&year=2012&month=03&from=United+States&to=United+States&ex=none&only=all&dataset=new&percentage=any) provides much benefit compared to the single current value of alpha. To facilitate this we have added PingER groups for N.AMERICA, EUROPE, AUSTRALASIA, S.ASIA, S.AMERICA.

Possible projects

Future meeting time - Les

Next meeting will be on Wednesday 27th June, 2012 at 8pm in US and Thursday 28st June, 2012 at 8am in Pakistan.
