Advanced Performance Model (APM)

Bandwidth Utilization Prediction Prototype

To improve the efficiency of resource utilization and scheduling of scientific data transfers on high-speed networks, we started a project on Advanced Performance Modeling (APM) that investigates and models a general-purpose network performance estimation framework. The performance prediction model and the framework will be helpful in optimizing the performance and utilization of fast networks as well as sharing resources with predictable performance for scientific collaborations, especially in data intensive applications. The prediction model estimates future network usage and the latency in using the network. Historical network performance information is used for throughput prediction without putting extra load on the resources by active measurement collection.
The details are describe in "Network Bandwidth Utilization Forecast Model on High Bandwidth Network", LBNL-6677E, 2014. (PDF)
