Mixvoip au plus haut niveau : Une collaboration étroite avec l'Université du Luxembourg

Like any research entity, the University of Luxembourg builds relationships with its economic environment. In this context, the Computer Science and Communications Research Unit, headed by Professor Dr. Pascal Bouvry, began with Mixvoip research and development studies back in July 2011 on a cloud-based VoIP solution, aiming for a dynamic adaptation of the system to lower the operational costs at the infrastructure level.

This project was named Supernode2, and the first work meetings took place in early 2012. Three work packages were set: the algorithm development, the installation of the application, and operation controls. Several engineers worked part-time on the project, and the very structured collaboration framework of Prof. Bouvry allowed the project to end in 2014.

Ana-Maria Simionovici, étudiante de doctorat, a déployé une architecture pour étudier les demandes spécifiques des appels VoIP, en utilisant l'expertise de Mixvoip pendant cette phase.

With the support of Mixvoip, Ana-Maria developed an Asterisk-based PBX system at the University of Luxembourg. The CEO of Mixvoip, Loïc Didelot, personally got involved in the DYMO and Supernode2 projects, both funded by the Luxembourg National Research Fund (F.N.R.) and Luxembourg Ministry of Economy, for the development of the Internet telephone system. Under the supervision of Prof. Dr. Pascal Bouvry and Loïc Didelot and Frederic Vanholder, manager of the UNILU-Mixvoip-FNR projects, very detailed and important milestones were reached.

An Application Program Interface (API) was decided upon between the involved parties to access the Call-Detail-Record (CDR) database from the company, with all details of the placed phone calls (e.g., prefix and destination call, details of the callee and caller). The data from the CDRs were analyzed, and the customers’ requests were modeled. Based on this information, load prediction and balancing were designed, developed, and performed.

Avec un peu d'aide, de soutien et de conseils Ana-Maria a proposé un premier état de l'art de la VoIP, au meilleur de nos connaissances, avec des détails allant des fonctionnalités, des modules de systèmes, des protocoles, à son développement dans le Cloud Computing (CC) et à son optimisation ultérieure qui combine la prédiction de la charge et l'équilibrage de la charge, avec l'objectif principal de réduire les coûts.

Although collaboration between universities and the industry is always challenging -each actor has its objectives- Ana-Maria found fertile ground at Mixvoip. She was welcomed as a team member, sharing the young company’s daily life.

This application can also optimize voice data traffic for the telecom provider, with the added guarantee of quality for the user. These architectural elements of the cloud PBX are invisible to customers but essential to be at the forefront of this market. This partnership between the University of Luxembourg and Mixvoip perfectly exemplifies a win-win situation and built strong links.

In October 2016, Ana-Maria graduated from Docteur de l’Université du Luxembourg en Informatique with the mention “excellent”, and Mixvoip on its side was still growing, recruiting its 28th staff member.

The young graduate said, “the right people at the right time”.
