L’institut Polytechnique de Paris regroupe cinq grandes écoles d’ingénieur·e·s — ENSTA, ENSAE, Telecom Paris, Telecom Sud Paris, École polytechnique — au sien d’un même établissement public.

Le LIX est fortement impliqué dans le développement d’IP Paris, notamment au sein de la composante Informatique, Données et Intelligence Artificielle (IDIA).

Le LIX entretient des relations très étroites et actives avec Inria. En particulier, plusieurs des équipes du LIX sont des EPCs (Équipes-projets communs) Inria : Comète, Partout, Crypto (Grace) et Cedar. En outre, depuis septembre 2012, le LIX occupe le bâtiment Alan Turing, qui est en copropriété avec Inria.

The Labex DigiCosme is an Excellence Laboratory (LabEx) built by the Scientific Cooperation Federation of Paris-Saclay. It is a proposition issued by the STIC community of the Saclay Plateau. DigiCosme is distinct from the Digiteo RTRA in two principal aspects: the Labex is more aimed scienfically along three axes (SciLex, ComEx, and DataSense), and performs net investments in education. These tree axes are:

• SciLex: security and semantics
• ComEx: networks and telecommunication
• DataSense: data and visualisation

The Digiteo RTRA is an STIC cluster covering the scientific domains of theory, design, development, and verification of software systems. It is a scientific cooperation federation created by the primary players in this domain on the Saclay plateau, including the École polytechnique, CNRS, and Inria.

The Systematic Centre groups a large number of industrial partners (PME/PMI and large enterprises) et and establishments of research and training in the Île-de-France region. The objective of this Competitivity Centre is to galvanize economic activity around digital technologies.

LIX is part of the Carnot Institute “Telecom and Digital Society” (télécom et société numérique). This institute is composed of 31 research laboratories distributed throughout France.
