Renater

Renater is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Renater rather than just read about it. In short: RENATER (Réseau national de télécommunications pour la technologie, l'enseignement et la recherche) is the national research and education network in France. Deployed at the beginning of the 1990s, RENATER (National telecommunications network for Technology, Education and Research) provides a national and international connectivity via the pan-European GÉANT network, to more than 1,000 education and research sites i…

Key takeaways

Renater belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Renater to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Renater from memory before moving on to harder problems.

Reference excerpt

RENATER (Réseau national de télécommunications pour la technologie, l'enseignement et la recherche) is the national research and education network in France. Deployed at the beginning of the 1990s, RENATER (National telecommunications network for Technology, Education and Research) provides a national and international connectivity via the pan-European GÉANT network, to more than 1,000 education and research sites in Metropolitan France and Overseas Departments and Territories. The RENATER network is an important and added value tool for research and education. It makes easier the collaborative work of the French researchers with their colleagues (data transfers and acquisitions, videoconferencing, spreadsheets etc.). RENATER is connected to international networks through two nx10 Gbit/s links to GÉANT and directly to the Internet through four nx10 Gbit/s links. RENATER supports IPv4 and IPv6.

Services The following services are offered to RENATER's community: Network services

IPv4 and IPv6 Connectivity End to end circuits (L2 and L3 MPLS VPN, optical paths,...) Resource management (prefix allocation, domain names registration,...) Applicative services

Authentication services (server and personal certificates) Education-Research identity federation Anti-spam service Mobility service (eduroam) Voice and image services (VoIP and video) Security service (CERT)

Worked examples

Example 1 — a first encounter with Renater

Start with the simplest possible case. Write down what Renater claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Renater before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Renater ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Renater

In research: Renater appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Renater in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Renater is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network stubs, Internet in France, National research and education networks, so understanding it makes those chapters shorter.
In everyday life: Look for Renater outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Renater in simple terms?

Why does Renater matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Renater?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
