Abstract

In this paper, we present a scalable protocol for conducting periodic probes of network performance in a way that minimizes collisions between separate probes. The goal of the protocol is to enable active performance monitoring of large-scale distributed computational systems and networks. We use the protocol to generate time series of measurement data that are then exposed to numerical forecasting models when a prediction of network performance is required. We present the protocol and demonstrate its effectiveness using the Network Weather Service - a tool for dynamically predicting network, CPU, memory, and storage performance.
