  1. Introduction


As an engineer-student in my 4th year of networking and telecommunications studies at the French engineering school INSA de Lyon, I decided to apply for the CERN summer programme of 2016 on my own initiative. My appliance has been pushed by the desire of living an amazing experience in an international environment while spending my summer in a very smart way.

I have been assigned a project where half of it was focused on engineering and the other half on computing. The overall goal was to develop a WEB interface that provides the access rights of users and E-groups to the different Subversion repositories. I worked under the supervision of Mr. Brice Copy in the BE-ICS-CIC division located on the Prévessin site of CERN.


  1. Presentation of CERN


CERN, which stands for “Conseil Européen pour la Recherche Nucléaire“, is the largest physics particles accelerator in the world. It is located few kilometres away from Geneva, in Switzerland, at the French-Swiss border in Meyrin. The rings of the Large Hadron Collider (LHC), which lied in a tunnel of 27 kilometres, extend on the French cities of Saint-Genis-Pouilly and Ferney-Voltaire.

Although CERN reputation is mostly based on its physics researches, it has an important place in the development of informatics technologies. The most famous one is certainly the creation of the World Wide Web at the beginning the 80’s by Tim Berners-Lee and Robert Cailliau. First developed to facilitate the exchange of information between searchers, it is now largely used all over the world.

CERN has also participated to the introduction of the Internet in Europe by installing the first two routers provided by Cisco (see Figure 1) on the European continent in 1987.



In addition, CERN developed technologies related to grid computing in order to process the important amount of data produced by the different physics experiences. Enabling Grids for e-Science (EGEE) is currently the most advanced project whose aim is to process the data generated by the LHC. It uses more than 41,000 processors belonging to 45 countries.
