SLAC SEECS Status report June 27th 2012

Attendees

Les was there but nobody else was available.

General

Asad has Confluence access.

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

Maggie1 was a problematic node. It was working fine because its disk space was temporarily increased. Anjum will get back to uson this because Joun had highlighted some issue with tmp clearing. Joun says this is OK.

PingER

Les has been invited to Nairobi, Kenya for the October 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 had a Skype meeting with Kuching on Thursday 6/21/2012. There will another meeting July 5, 2012. The minutes are here .

HEC Report - Anjum, Amber and Imdad

Amber is working on this report. The basic structure is the same as 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. Email sent to Amber 6/23/2012.

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. A reminder was sent to Joun 6/23/2012, and Anjum also asked Joun for progress 7/24/2012.

  • 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
  • Joun reports these nodes have some administrative issue and not cooperating with us. They have already written a letter to HEC to resolve this sissue and that letter is still under process. Joun is not sure that when this problem will be actually resolve. We are just waiting for the response by HEC and still considering them as a monitoring nodes.

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 

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 has an account at SEECS and SLAC. He has the codes etc. Raja has been going through the documentation sent to him by Les. He was facing difficulty accessing the SEECS server but then he managed to connect and copy the TULIP and CBG code. He was able to successfully run the CBG code using input file as described by the comments in the files. Currently he is going through the files trying to thoroughly understand how exactly each function is working. Following this 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. Progress?

A following 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

Normal next meeting would be on Wednesday 4th July, 2012 at 8pm in US and Thursday 5th July, 2012 at 8am in Pakistan. Since July 4th is a holiday in the US, we should probably re-schedule. Umar believes the onus is on the troop in Pakistan (Raja, Joun, Anjum). Let us wait for their response. It all depends on what they are doing? What they plan to do? Do they need our input? Umar would want to skip next week, to celebrate Britain's magnanimity (wink). However, if the gentlemen in Pakistan want to meet, h'd be happy to join.
