There was a Bangladesh Research and Education Network (BDREN) conference (MEETBDREN) in Dhaka on April 17-18, 2016 that Les was invited to give a talk presenting the results of network monitoring by PingER especially as related to Bangladesh. Unfortunately I was unable to attend, however we put together a case study and set of slides that I could either present remotely or an attendee could present.

Long term performance of Bangladesh seen from SLAC

Comparison of universities connected by BDREN with those not so connected

Another attendee (Md. Nadir Bin Ali, Deputy Director, IT, LMC, Cisco Networking Academy, Daffodil International University, 102 Shukrabad, Mirpur Road, Dhanmondi, Dhaka, Bangladesh) requested assistance to compare the network performance for universities connected to BDREN with those connected to non BDREN ISPs.

Getting another non BDREN MA in BD will require some site setting up a PingER MA, and making measurements. By the time the site and MA has been identified and the pingerpinger2.pl installed I doubt there will be many measurements by the time of the conference with enough time to analyze the results and draw conclusions.  On the other hand setting up the Daffodil MA to measure multiple sites in BD is much simpler and quick, so some measurements could be available for analysis before the conference. They may not be as complete as those from multiple MAs but they may provide useful information. To add extra hosts see here.

I ran a script to get potential Bangladeshi web servers that have been seen by Google and pinged each in turn to see if it responds and the Round Trip Time (RTT) if it does respond, The result is seen here for ,edu and .ac hosts (presumably Universities).

We also need to determine if the hosts are on BDREN or another ISP. I looked up BDREN to see which sites are on BDREN at http://www.bdren.net.bd/member.php, and created a spread sheet of BDREN hosts in Bangladesh that I can ping that are www servers, are in either edu.bd or ac.bd (I also added known BDREN hosts) together with which hosts are on BDREN and if on BDREN whether and  whether the host responding to pings has a RTT of ~ 250ms seen from SLAC  (i.e. likely to be in Bangladesh). There is a spreadsheet with Bangladesh University web site host name, the IP addresses,  their RTTs seen from SLAC, and whether their ISP is BDREN .
