Abstract

This paper introduces DAUTI, a network traffic simulator, applies it to a simulation research problem, and demonstrates the ease-of-use and applicability of functional languages to network simulation. DAUTI is an Open-Source, fully configurable, rapidly advancing, and efficient Scheme program that can be used to simulate Cluster load and job delay on any size of network, and provide basic statistics and analysis. In this paper, we use DAUTI to compute the relative performance of load distribution algorithms on a two-stage pipeline with heterogeneous cluster sizes. Specific applications include web servers, and industrial, research and financial batch processing. The choice of the Scheme language (a relative of Lisp) presented numerous opportunities to quickly produce compact and efficient code. This language selection incurred no obstacles.
