Web-based computer applications connect the end-user with information via the internet. These applications typically operate in distributed computing environments, collecting and collating information from multiple computers that host databases or traditional computer applications. The increase in internet traffic is a clear reflection of the increase in demand for various web-based applications. Managers often find it essential to have the capability to predict performance of these systems in order to maintain service levels, as measured by response time. We present a generic discrete event simulation tool for modelling web-based application systems. Modelling information flow for decision making in such systems requires constructs not typically available in simulation software. We have developed several constructs that can be used in constructing models for various kinds of web-based applications. An example system is modelled using the tool, the impact of different variables (eg transaction volume) on the system performance is analysed and some preliminary insights are presented.

“…As a result, modeling the performance of computer networks is without any doubt a crucial and difficult interdisciplinary subject. The principal idea behind simulation modeling is to represent accurately the topology and functions performed in a network in order to obtain statistical results about the network's performance under investigation [2]. Computer networks can be categorized based on the nature of data transmission in three different types; namely, the copper networks where the electric voltage is used as the transmission medium, the optical networks where the light is used and, finally, the wireless networks where electromagnetic waves are used for the transmission.…”

The increasing complexity of computer networks calls for the development of new models for their simulation. Cellular automata (CAs) are a well-known and successful model for complex systems. This paper presents a system for modeling and simulation of computer networks based on CAs. More specifically, a 2-D NaSch CA computer network model has been developed, and several networks were simulated. Algorithms for connectivity evaluation, system reliability evaluation, and shortest path computation in a computer network have also been implemented. Our system, called Net_CA system, was designed and developed as an interactive tool that offers automated modeling with the assistance of a dynamic and user-friendly graphical environment. The proposed system also produces automatically synthesizable very high speed integrated circuits hardware description language code leading to the parallel hardware implementation of the aformentioned CA algorithms. In terms of circuit design and layout, ease of mask generation, silicon area utilization, and maximization of achievable clock speed, CAs are perhaps the computational structures best suited for a fully parallel very large scale integrated realization. The simulation algorithms developed in the present paper offer high flexibility. Furthermore, connection reliability and other important parameters are inputs to the algorithms, rendering Net_CA a very reliable and fast simulator for wireless networks, ad hoc networks, and generally, for low connection reliability networks.
