LEGS: A WSRF Service to Estimate Latency Between Arbitrary Hosts on the Internet

: The ability to estimate the communication latency between arbitrary hosts on the Internet would enable the distributed computing applications to find the closest server or to find the closest replica of the data required for the computation. Internet content providers, who often place data and server mirrors throughout the Internet to improve access latency for clients, can use this as one of the metrics to find the appropriate mirror for the clients. It could be useful for constructing topologically sensitive overlay networks. In this paper, we present Latency Estimation Grid Service (LEGS), a Web Services Resource Framework (WSRF) service that is built on top of a tool called King to estimate latency between arbitrary hosts using recursive DNS queries.
