This repository contains an event-driven simulator for elastic optical networks to study the problem of routing, modulation, and spectrum allocation (RMSA), as well as quality of service metrics. In the event that the simulator is utilized in an academic context, proper citation is required.

More detailed documentation is currently being written. Please wait. Consider visiting the official page for this application.

Scope and Features

The scope of this project consists of analyzing network behavior in different configuration contexts, such as topology, traffic, routing policies, and resource allocation. Multiple topologies are available by default, however, it is possible to use any desired topology, as long as it follows the application standards.

The algorithms available are: - Quality of Service: Absolute Fragmentation, External Fragmentation and Entropy-based Fragmentation. - Routing: Breadth-first Search, Depth-first Search, Dijkstra's algorithm and K Shortest Paths. - Spectrum Allocation: Best fit, First fit, Last fit, Random fit and Worst fit.

Building From Source

First install and configure all necessary dependencies, then clone this repository:

bash git clone git@github.com:AssoDePicche/elastic-optical-networks.git --recursive

After that, use the available scripts to perform the build, tests, and profiling.

bash ./scripts/build.sh

Running

Once the application has been built, you can run it. To modify the simulation parameters, edit the settings.json file.

bash ./build/App

When the simulation ends, it saves a .csv file with the simulation data and a report.txt file is created with the results.

A Bit Of History

In August 2023, I began my scientific initiation program under the guidance of Dr. Rodrigo Campos Bortoletto (ORCID) in the LABCOM³ research group for the study of Elastic Optical Networks. Since then, I have sought to contribute to the academic community through the development of this software.
