Description: The Network Weather Service is a generalizable and extensible facility designed to provide dynamic resource performance forecasts
in metacomputing environments.In this paper,we outline its design and detail the predictive performance of the forecasts it generates.
While the forecasting methods are general,we focus on their ability to predict the TCP/IP end-to-end throughput and latency that is
attainable by an application using systems located at differentsites.Such network forecasts are needed both to support scheduling
(Bermanetal.,1996)and,by the metacomputing software infrastructure,to develop quality-of-service guarantees(DeFantietal.,to
