Model-Driven Performance Analysis Methodology for Distributed Software Systems

Abstract

Abstract-A key enabler of the recently popularized, assemblycentric development approach for distributed real-time software systems is QoS-enabled middleware, which provides reusable building blocks in the form of design patterns that codify solutions to commonly recurring problems. These patterns can be customized by choosing an appropriate set of configuration parameters. The configuration options of the patterns exert a strong influence on system performance, which is of paramount importance in many distributed software systems. Despite this considerable influence, currently there is a lack of significant research to analyze performance of middleware at design time, where performance issues can be resolved at a much earlier stage of the application life cycle and with substantially less costs. The present project seeks to develop a performance analysis methodology for design-time performance analysis for distributed software systems implemented using middleware patterns and their compositions. The methodology is illustrated on a producer/consumer system implemented using the Active Object (AO) pattern in middleware. Finally, broader impacts of the methodology for middleware specialization are also described.

Performance evaluation of the reactor pattern using the OMNeT++ simulator

“…There have been efforts to evaluate the performance of middleware patterns analytically by various researchers [2], [6]. A drawback of using analytical models is that it is difficult to predict the behavior of a complex system based on analytical methods alone.…”

Beneficios que aporta la metodología MDE a los entornos de desarrollo de sistemas de tiempo real

“…Por estos beneficios, la metodología MDE se aplica con gran éxito en diferentes tareas de la ingeniería software, como por ejemplo, en la generación de código a partir de modelos, en el desarrollo, ensamblado, configuración y despliegue de tecnologías de componentes, en el desarrollo de pasarelas para la inter-operatividad entre entornos de diferentes fabricantes, etc. También se ha aplicado la metodología MDE al diseño de sistemas embebidos y de tiempo real (Balasubramanian et al, 2006;Gokhale et al, 2007;Henzinger & Sifakis, 2007;Moreno & Merson, 2008), si bien de forma más limitada y en muchos casos como pruebas de concepto.…”
