Aggregation and Evaluation of Communication Data of Large Telepresentation Infrastructure based on Computing Nodes on Critical Endpoints

Abstract

This paper introduces an architecture of model solution for aggregation, evaluation and in the last step also visualization extended data related to videoconferences held by heterogenous environment of Slovak's National Telepresence Infrastructure (NTI). The main aim of this system is to properly process, and aggregate multiple attributes of videoconferences obtained on computing nodes located on critical endpoints and display them graphically for a straightforward overview. Different types of graphs are used to visualize basic videoconferences properties, while for overall statistics table visualization is used. Processed historical data is subsequently used to predict the upcoming number of videoconferences in near future and the number of videoconferences related to the particular organization for the modeled period.
