Administration

Geolocation Anjum, 

  • This is a proposed project for one of the Indian students.

Android - Bebo 

Bebo has set up a Github codebase  as a new project. It contains the PingER MA (pinger2.pl and the traceroute/ping server). Anyone  needs to sign up for a Github account (if you don't already have one), so you can be added as a project member.

  • slac-pinger/pinger created by topherwhite.  PingER project https://github.com/slac-pinger/pinger
  • Now we have it we can share with Amity to check it works.
    • Bebo reports that someone from Amity requested to be a member of the Android group.

...

UUM

  • Saqib has a  5  MS students from the Database team

    • Sara Massoud came up with ideas to improve the info put together by Amity

    • Sabah Massoumil working on Linked Open Data (please excuse spelling)

    • Aqsa Hameed working on big data/analysis of PingER data. The initial idea was to set up a big data/big analysis 

    • Aqsa Hameed has been working with Anjum to look at a project to create a Hadoop/Cloudera PingER warehouse to enable easier, more powerful access to PingER historical data. 

      • Thinking a bit on Aqsa her work appears to be related to the work done by Thiago on PingER warehouse using a cluster/Cloudera/HDFS/Impala earlier this year. In particular see the presentation at NETAPPS2015 (see https://confluence.slac.stanford.edu/download/attachments/123309267/NETAPPS_PRESENTATIONrevLuiza.pptx. Once the paper is published we can also provide her with that (Adib will let us know when this is OK). 

      •  Les emailed the relevant people to put them in contact with one another. It appears there is a lot of overlap between what Aqsa proposed as a Masters project and what Thiago has already done. However Thiago's system was mainly a proof of concept and not in production. We need to look at the next steps: Internet access, auto-updating of information in near realtime, production service, maintainable etc. With this in place one could really mine the data looking for all kinds of interesting correlations, clustering, event impacts, comparisons etc.

        • Given that such a warehouse is available, then the next step would be to automatically create queries that would produce in near real-time the plots we produce manually for the PingER annual reports.

        • Following this publish the data in RDF to tie in with the Southampton RDF web observatory repository (similar to what Renan did as a proof of concept).

        • Since Thiago's warehouse is only available at SLAC,  it may assist to get Aqsa an account at SLAC, alternatively Aqsa will need to set up a repository at here home base.

        • There is some documentation written by Les on the usage of the warehouse at SLAC. It is at: PingER Data Warehouse using Big Data with Cloudera on Nebula.

        • Les will contact Thiago to see if there is other documentation or where to find the programs etc.

        • We need to put together all we know:

      • Tehseen is working on missing PingER data.

  • Saqib has submitted a project with title "A Fundamental Active Internet Performance Monitoring Framework for Pakistan Education & Research Network (PERN) in University of Agriculture, Faisalabad"

    • Project is accepted.

    • working on a project to develop a node using Raspberry Pi 2 and IoT to measure the air and soil quality.

      • Have 2 RPis and setting up air quality with sensors from market, idea is to distribute on campus.

    • Currently, students are analyzing the project to develop a problem statement for their research project.

  • For the GeoLocation Saqib should contact Anjum

  • Project on Internet performance has been accepted, but no funding yet.

UUM

Fatima  presented her work at NetApps. Fatima has passed her master oral examination (Viva) with minor correction and she is submitting her final dissertation coming Sunday to UUM school of computing. Indeed, we are very grateful to PingER team members support and help. Currently, Fatima is planning to pursue her PhD and possibly on a topic related to her master dissertation. We need PingER team suggestions and advice before we can decide on the topic. Adib will attend next meeting to further discuss on this.

UM

Ibrahim has extracted the  PingER Zip manually. He is reconstructing 11Gb of data, has 15GBytes of data there. He is trying to use SPAR to classify the data. He also was looking at RDF. the next step is to use MapReduce to organize and reduce the output of data so can visualize it. He will be using a the same techniques he used for looking at 1996-2006 weather data.  However at the moment he cannot access his  VMs from myren for the last two weeks, even for the myren site, He has emailed  them but till now they have not fixed the issue.  He has updated all his data in their cloud. No update 1/6/2016

  • Fatimah: she has decided to take one semester off before she pursues her PhD. She is planning to use this semester to explore the area more and finalize her PhD topic. Any suggestions or ideas are welcomed.
  • PINGER IPv6: I have one  Practicum student interested to work on PingER IPv6. Based on the information provided in PingER site, “(pinger2.pl) will work with both IPv4 and IPv6”  while “ping_data.pl will need some mods also.” Following our today’s meeting, the student is expected to create ping6_data.pl which will work on flat file (just to be specific). Dr. Les, has suggested to provide an account for us at SLAC to be able to test. In addition, it would be great if we can get some documentation about ping_data.pl so the student will get clear understanding on how the current system work and this will help him to progress faster.

NUST

Hassaan reports: "There are total of 48 active nodes for Pakistan out of which 18 nodes are working properly whereas 4 nodes have configuration issues. Lahore college for Woman has changed its data center and they want to know what do have to do with the new one. Faisalabad PERN had some critical issues and burnt their power supply so they also wanted to know what can be done to overcome that damage. FAST University Karachi and Air University, Islamabad are not in a mood to help as they say that they will put the node up, but haven’t done that in past 2 months [Hassaan would like to discuss this with Dr. Anjum for excluding them from the list]. Last but not the least Quetta HEC regional center wanted to change their static IP to 121.52.157.148."

PingER at SLAC

Put together a web page on the Fertility Rate and PingER measured Internet performance. The concern is the high Fertility rate in Sub-Saharan which is dominating the global growth in population and could result in over 6B people in Africa and 11B people on the planet by 2100. This puts a huge strain on resources. To reduce the Fertility Rate one needs education and information which is greatly enabled by the Internet. Unfortunately Internet performance is generally at its worst in West, Middle and East Africa where the Fertility Rates are highest. 

...

The 2016  annual report on network monitoring is almost ready, it includes a section on PingER.

Old Items

UOA (Saqib) placed here 2/3/2016.

...

  • Jan 5, 2015 Hassaan reports "I have received revisions on my proposal and these days I am revising my proposal. In the meanwhile, I have also added another student (Anas Abrar) on this project. He is in learning phase and will follow the nodes which are not working. I shall give you an update very soon. "

    •  Hassaan is  very hopeful that if the proposal is accepted then we can easily have a full time RA for the project.

    Hassaan has re-submitted the proposal after revisions. He would like to get Anas Abrar more trained on monitoring operation and then will inform us to add him to the mailing list at http://pinger.unimas.my/pinger/contact.php.

     

  • Oct 2015. Following the last meeting, Anjum, Hassaan and Les met to discuss the way forward. 

    • "Adnan currently is unable to find resources for handling the project. Similarly, there is no progress on hiring of a full time RA by NUST HQ. 
    • However, I (Hassaan) checked from HEC about the proposal that I submitted last year. They have informed me that 2 reviewers have asked for revisions while they are waiting for the third review. I am very hopefull about it. If the proposal is accepted then we can easily have a full time RA for the project. I have plans to talk to Dr. Zaidi about hiring an RA on assuming that our proposal will be accepted by HEC. We can then get his salary deducted later from the HEC project. I shall update you very soon in this regard." 

    • Hassaan is  waiting to hear from HEC about the comments on the proposal. 

    • Moreover, he has asked a student to work on the project for the time being. His name is Mian Anas however he will need few weeks to understand the project. 

  • Thiago completed setting up the  PingER data SQL Impala warehouse running on a Nebula/Cloudera cluster using the Hadoop File System (HDFS). Unfortunately it is not currently accessible from outside SLAC. There have been several attempts to provide outside access, but no success yet, we need to engage the subject matter experts. Thiago is now a SLAC associate so he still has an account at SLAC. There was a cyber security alert on the version of java installed with Cloudera. Les has replaced the cloudera version of java which should fix the vulnerability. However the new version has not been tested.

Geolocation

Anjum believes the TULIP Geolocation application  can be improved significantly. At least there are few ideas that we can try. For this, either a group of undergraduate students or an active masters student is required. The resultant work can easily be the thesis of masters level. Who is interested? 

  • Saqib at Faisalabad has an MS student interested to work on Geolocation project. He requests an initial  paper on the project.  Les has responded to Saqib. He also has some other students. Anjum will contact him. Potential projects/asks include: take over management of PingER monitoring in Pakistan (say 5 monitors/student; case study of how Pakistan's network performance/connectivity has improved over thea years especially as function of funding etc;  geolocation with variable alpha; indoor geolocation

  • Johari will contact Anjum to learn more of the requirements. Update Johari/Adnan

  • See http://www.slac.stanford.edu/comp/net/tulip/. Basically TULIP uses pings to a target from landmarks at known locations and converts the minimum RTTs to estimate the distances. Then uses the distances with mulitlateration to estimate the location of the target

  • To improve TULIP one needs the right selection of landmarks, i.e. good (working landmarks) at the right locations (not too far from the target), straddling the target, and with a a reasonable estimate of the indirectness (directivity or alpha) of the path from the landmark to the target (so we can reasonably accurately estimate the distance). One also needs a reasonable density of landmarks (e.g. number of targets/100,000sq km)

  • The landmarks come from PingER and perfSONAR sites.  We have a reasonable density in the US, Pakistan and Europe. Currently Anjum is getting better than 20km accuracy for Pakistani targets

  • As the number of landmarks goes up so does the accuracy, but so does the time to make the measurements (pings). 

  • One needs to find the optimal density

  • Anjum proposes to speed up the measurements using a cluster for parallelization and also proposes to improve the adaptation of alpha based region. He regards the adaptive geolocation and parallelization as  MS projects. 

  • He is also interested in geolocation in small proximity (e.g.indoors), e.g. using cell tower signals. This is a new area of research. It is possible that the port of PingER to an Android could  be related to this. This is a PhD project

  • Anjum reports he can supervise the students on Geolocation. He will need to know when the students are ready. We can start with a joint meeting involving Les and the students. Later on, Anjum can have the meeting with students every week while Les can join if he has time.

NUST/SEECS Pakistani PingER nodes status

Pink Background indicates host was bad last month, strike through says it is fixed, yellow is an new bad host.

...

Is it time to start paring down the list of PingER monitor hosts in Pakistan, starting with those that have been down for a while and despite your efforts they are not cooperating.  One might also look at the coverage by region in Pakistan and try and keep good coverage for all regions.

Traceroute at UTM 5/9/2015

The traceroute problem regarding maximum reachable hops ( i.e. 11 hopes ) may be since the Unix/Linux/OSX  traceroute uses UDP to send the requests. The first request is sent to a particular port (33434), with a ttl  to tell it how many hops to go to.  The ttl starts at 1 is incremented as it tries the next hop, also the port is incremented (up to 33465).  It looks like the first few UDP ports are enabled and then they are blocked. The Windows traceroute uses ICMP to send the probes so does not see the problem.

Linked Open Data

Cristiane reports (7/1/2015): "I am trying to automatize the triplification of PingER data on Kettle. For now, part of the transformation is made on Kettle and another is made by a Java code. Although this solution works for a data sample, is important to have the entire process on Kettle because it facilitates to understand, modify and control the triplification process."

...

Christiane's report is at: Size Inflation of PingER Data for use in PingER LOD

UM

Moved here 3/4/2015:

Ibrahim has setup distributed hadoop clusters. He has 2TB of disk space. Les has provided information on getting a subset of PingER data by anonymous ftp via ftp://ftp.slac.stanford.edu/users/cottrell.  It was put there last September. Information on how the data was put together is at https://confluence.slac.stanford.edu/display/IEPM/Archiving+PingER+data+by+tar+for+retrieval+by+anonymous+ftp. There is information on formatting etc at http://www-iepm.slac.stanford.edu/pinger/tools/retrievedata.html and some on the dataflows at https://confluence.slac.stanford.edu/display/IEPM/PingER+data+flow+at+SLAC. Renan at UFRJ has successfully used this data, he has also characterized the data in terms of bytes/metric per year etc.

...

Anjum reported that UM had experienced a TCP syn DOS attack prior to Mar 12th (when an IDS was put in place). It occurred mainly for several days before between the hours on noon- 2pm and 7-7 in the evening (Malaysia time). He suggested looking to see if PingER could spit the effect.  Ibrahim, Les and Anjum will look at. Les analyzed the data and sent it to Anjum

NUST

The following is from Samad 2/24/2015.

Follow up from workshop
  • Hossein Javedani of UTM is interested in anomalous event detection with PingER data. Information on this is available at https://confluence.slac.stanford.edu/display/IEPM/Event+Detection. We have sent him a couple of papers and how to access the PingER data. Hossein and Badrul have been put in contact. Is there an update Badrul?

...

Anjum suggested Saqib,  Badrul and Johari put together a paper on user experiences with using the Internet in Malaysia as seen from Malaysian universities. In particular round trip time, losses, jitter, reliability, routing/peering, in particular anomalies, and the impact on VoIP, throughput etc.  It would be good to engage someone from MYREN.

Ibrahim

Ibrahim Abaker  is planning to work on a topic initially entitled " leveraging pingER big data with a modified pingtable for event-correlation and clustering".  Ibrahim has a proposal, see https://confluence.slac.stanford.edu/download/attachments/17162/leveraging+pingER+big+data+with+a+modified+pingtable+for+event-correlation+and+clustering.docx. Ibrahim reports 7/15/2014 "I have spent the last few months trying to understand the concept of big data storage and its retrieval as well as the traditional approach of storing RDF data. I have integrated a single hadoop cluster in our cloud. but for this project we need multiple clusters, which I have already discussed with Dr. Badrul and he will provide me with big storage for the experiment." No Update 8/20/2014.

"I have come up with initial proposed solution model. This model consists of several parts. The upper parts of the Figure below shows the data source, in which PingER data will be convert into RDF format. Then the data pre-processor will take care of converting RDF/XML into N-triples serialization formats using N-triples convertor module. This N-triple file of an RDF graph will be as an input and stores the triples in storage as a key value pair using MapReduce jobs"
