Model-Based Throughput rediction in Data Center Networks


In this paper, we address the problem of performance analaysis in computer networks. We present a newmeta-model designed for the performance modeling of network infrastructures in modern data centers. Instances of ourmetamodel can be automatically transformed into stochastic simulation models for performance prediction. We evaluate the approach in a case study of a road traffic monitoring system. We compare the performance prediction results against the real system and a benchmark. The presented results show that our approach, despite of introducing many modeling abstractions, delivers predictions with errors less than 32% and correctly detects bottlenecks in the modeled network.
