Description
This dataset contains measurements of the latencies between a set of DNS servers. It was used as the basis for evaluating the Vivaldi network coordinate system among other distributed systems.
King estimates RTT between any two hosts in the Internet by estimating the RTT between their domain name servers. In order to do this, King depends on the following fact which hold true for most of the domain name servers in the current Internet. Most domain name servers in the current Internet (~75%-80%) support recursive queries from any host in the Internet. The accuracy of King depends crucially on another fact about the domain name servers in the Internet. In many cases the name servers are located close (measured as network latency) to their hosts. While the first fact is the result of a default choice by many name server administrators the second fact arises more out of administrative convenience than anything else.
