Simulator for Performance Analysis of VOQ Switches

This paper presents software tool we develop for performance analysis of VOQ switches. There are not newer scheduling algorithms like DRRM, EDRRM and uFORM in available v.2.35 version of the SIM software. Because of that, we developed software tool, called VOQ simulator which covers all scheduling algorithm schemes we found in relevant scientific papers including algorithms which are not present in the SIM simulator. VOQ simulator is slotted time simulator written in Java programming language and has a modular architecture. Because of this modular architecture many different combination of these functionality blocks can be easily simulated. This is an application with simple graphical user interface where users define parameters for which they want to analyze the performance. This simulation tool gives the results that are compatible with results we found in literature. Also, we have extended original analysis of uFORM algorithm by modeling of this algorithm scheme for multiple iterations.
