Anjum believes he can add two more PingER hosts, one at Bahawalpur the other at Sahiwal. These are in central Pakistan towards the Eastern border and so should help with providing TULIP landmarks. However with his impending move he has not had time to follow up. Hassaan will follow up with Anjum. Progress?

TULIP - Raja
We are looking to make the code open source and available via github. We will be discussing possible extensions and potential commercializationhave sent email to Yahoo giving them an update on TULIP and how it might be extended to meet their needs.
Raja has found a further ~48 perfSONAR landmarks mainly in Europe and N. America. We now have 228 active unique landmarks. He now checks for new landmarks on a monthly basis. We have also created Taiwan as another region for which we can get good location information. We now work for N. America, Europe, Pakistan and Taiwan.
Raja has made lots of measurements and created cumulative probability distribution functions of how the new TULIP with adapting alpha (in distance = Alpha*100(km/ms)*min_RTT(ms)) according to region and min_RTT compares to databases and Constraint Based Geolocation and Single Ping etc. He has also added information on the impact of landmark density on accuracy.Raja has put together a paper on TULIP. It has been submitted.
As the ICFA report winds down and Raja's work on TULIP begins to go into testing he will be engaging more with Renan and Linked Open Data. Raja has sent email to Renan and has a list of things from Renan that Raja should look at. This is delayed by finishing off the TULIP paper and the end of year PingER annual report for ICFA.
