SLAC SEECS Status report July 3rd 2012

Attendees

Umar was present but nobody else. Les was delayed and did not get on until 8:25pm Pacific time. Raja was unaware of a meeting since he was not on the mailing list. Zafar's Internet connection was not working. The main telephone cable of his sector was cut by a bulldozer and he didn't have connectivity for almost two days. Sadia did not have connectivity for a day in her area either.

General

Arshad should arrive in the Bay Area on July 5th.

Fahad has added Raja to seecs-cern@googlegroups.com.

Umar talked to Anjum. Lack of funds is a problem. NUST will not continue funding. HEC funding has run out. If we have 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 around July 5th, 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 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 was working on this report. Amber talked to Dr. Anjum about report submission. He said that old report is not required now. We might submit a report sometime later.

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. 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. For the record the nodes 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

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 

Raja was able to successfully obtain the coordinates for several input files using all three methods i.e. (Speed of internet, Speed of light and CBI best fit). Currently he is going going through the Matlab codes and following Mathematica tutorials; this will enable him to transfer the current code to Mathematica.

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 11th July, 2012 at 8pm in US and Thursday 12th July, 2012 at 8am in Pakistan.
