Dynamicallyforecastingnetworkperformanceusingthene

  网络服务正在更新换代并且可扩展设备被设计成可提供在元计算环境中动态资源行为预测。这篇文章里，我们描述了预测产生的的设计和预测行为的细节。当预测方式为普通方式时，我们关注与他对TCP/IP端到端吞吐量能力的预测和在不同地点使用不同系统会带来的延迟量。因为在元计算软件的基础上网络预测需要计划的支持和质量服务保证的提高。(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 appear Grimshawetal.,1994). )
