Training: BELLA Project offers free courses on optical networks and networks defined by software

Both courses are part of the training activities developed by the BELLA project (Building the European Link with Latin America) and are now available free of charge to all those interested at CLARA’s EDX platform.

Through both courses, BELLA aims to prepare the National Research and Education Networks of Latin America, and the network engineers of its affiliated institutions, for the substantial change that RedCLARA's new optical backbone, which is being developed through BELLA, will impose.

In the course "Optical Network Systems" the students will have the get access to the concepts and foundations of Dense Wave Division Multiplexing (DWDM) and Coarse Wave Division Multiplexing (CWDM) optical network systems. The content includes the theoretical description of the types of modulation used for the transmission of multiple optical channels on an optical fiber wire, and describes the elements that affect the transmission, as attenuation, dispersion and non-linear effects that must be taken into account when designing or operating optical networks.

The networks defined by software, in turn, constitute the new paradigm in network architecture, which seeks to improve flexibility, programmability, cost and security in data networks. Move from an intelligence model distributed in the network elements to a centralized control model, with switches based on the Openflow protocol. In this course, students will understand how this protocol works, its characteristics and the network elements involved in a software defined network architecture (SDN). The students will also have the opportunity to perform practical exercises, using the Mininet simulator, Open vSwitch and the Opendaylight driver.

The courses are taught by experts in the respective areas, namely Dr. Ricardo Alberto Olivares Veliz, Head of the Department of Electronic Engineering at UTFSM, Valparaíso, Chile (Optical Network Systems), and Javier Richard Quinto, Master of Electrical Engineering in the Area of Computer Engineering by the State University of Campinas (UNICAMP) and student of Doctorate in Electrical Engineering in the Area of Computer Engineering, also by the UNICAMP (Networks defined by software).

The CLARA EDX platform works better with current versions of Chrome, Firefox or Safari, or with Internet Explorer version 9 and higher. To register, simply access the EDX module through Colaboratorio, click on the desired course and fill out the registration form. After registration, more information will be sent to your email.


BELLA II receives funding from the European Union through the Neighbourhood, Development and International Cooperation Instrument (NDICI), under agreement number 438-964 with DG-INTPA, signed in December 2022. The implementation period of BELLA II is 48 months.
