Lições aprendidas no projeto e implementação de uma ferramenta de comunicação em grupo baseado no paradigma de canais de eventos.

Abstract

This work discusses the advantages and disadvantages of building high-level communication protocols using the model based on event channels as internal structural form. It is realized a theoretic and experimental comparative study with the layer based model, that is the most spread out between the specialized communication protocols that exist. At the beginning, we present the concepts of each studied model, discussing their main virtues and problems. To follow we present the functionalities of the iBusTF and iBusTFE, that are the specialized communication protocols, more specifically group communication tools (GCT), used to make the experimental comparison between both of the structural models. We stand out that the iBusTFE was built with this purpose, and therefore he has the same functionalities of the iBusTF, however, the iBusTFE uses the model based on event channels as its internal structural form, instead of the layer based model. Then we present the methodology used to compare both of the studied models and which were the adopted measures to eliminate what the influence of adverse factor on the tests. Finally, we present the data that was obtained at the tests and we make the its analysis, trying to verify if the hypotheses raised at the conceptual discussion were confirmed or not.
