Data Set: Vivaldi Network Coordinate System in Azureus

We have developed a crawler that allows us to obtain from over one hundred thousand peers running Azureus their network coordinates and to measure the network and application level round trip times to these peers.

A full analysis of the data can be found in the following paper:

Where is my Peer? Evaluation of the Vivaldi Network Coordinate System in Azureus

On this website you can download the dataset called Mannheim in the paper. The crawler is at the University of Mannheim, which is attached to the German research network. The data set contains one single crawl performed on March 31, 2008, at 08:00 CET. 1,044,155 peers have been discovered, 291,850 responded to the crawler (Azureus application layer RTT and Vivaldi network coordinates are available). 157,205 peers also replied to the TCP ACK packet. For those peers, also the network level RTT is available. The crawl duration was 12 minutes.

The data sets contains the Vivaldi network coordinates version 1 and version 2, the Vivaldi distances to the crawl site, the application- and the network level RTT, and the country (resolved with MaxMind).

We removed from the data set for privacy reasons the IP address, the port, the Azureus peer ID, the estimated number of peers in the network. Moreover, we removed the statistics every peer collects.

The file contains one line per peer. The first seven columns contain the data related to Vivaldi version 2 (columns 2-5 the coordinates, column 6 the height, and column 7 the Vivaldi distance to the crawl site). Column 8 to 12 contain the data related to Vivaldi version 1 (Column 9+10 the coordinates, column 11 the height, and column 12 the Vivaldi distance to the crawl site). Column 14 contains the ARTT and column 15 contains the NRTT (if available, otherwise -1) from the crawl site.The last column, column 16 contains the two letter country code, in order to obtain it, we resolved the IP address with MaxMind.
