IT systems rely on high-performance network infrastructures to enable millions of complex and varied technology platforms all over the world to communicate with each other. Network infrastructure is the heart of IT systems. Discover the definition of network infrastructure, its essential components and the importance of choosing the right type of infrastructure to meet growing connectivity and security needs.

What is network infrastructure?

Definition of network infrastructure

At all modern companies, there's a vital system at the heart of their business, one that's often invisible, but of vital importance: their network infrastructure.

But what exactly is it?

Network infrastructure refers to all the hardware and software components that enable communication and data exchange between different devices within an organization and with the outside world. It is an essential pillar of IT, supporting everything from Internet access to the operation of mission-critical applications. This infrastructure includes a circulatory system made up of various interconnected elements, such as routers, switches and cables, as well as virtualization technologies to manage resources efficiently, with resilience in line with advanced technological evolution capabilities.

The components of a network infrastructure

The components of a network infrastructure include physical elements such as servers, cabling and connected peripherals, as well as logical elements such as communication protocols and network management software.

•       Servers: play a central role in storing and processing information.

•       Routers and switches: for data distribution and routing purposes - respectively.

•       Firewalls and security systems: ensure the security and sensitive protection of data from internal and external threats.

•       Cables and wireless connections: for data transport.

What are the different types of network infrastructure?

Networks are set up to transfer data from one system to another, or to provide shared resources. Depending on the size and scope of the computer network, it is possible to differentiate 4 major types and categorize them as follows:

Local Area Network (LAN)

A LAN (Local Area Network) is a network infrastructure that connects devices in a limited geographical area, such as an office or building. It generally uses technologies based on a common, widespread standard for wired LANs called Ethernet protocol. In this type of network, data transmission is either based on copper cables or via fiber optic cables to provide a fast, reliable connection.

Metropolitan Area Network (MAN)

The MAN(Metropolitan Area Network) is a broadband telecommunications network that connects several LANs geographically close to each other, usually within a city or conurbation. It is often used by companies to interconnect several remote sites via leased lines in the same geographical area, enabling efficient communication on a larger scale. High-performance equipment and high-performance fiber optic connections are used between two or more remote nodes to provide high data speeds, creating the impression of being in the same LAN.

Wide Area Network (WAN)

WANs (Wide Area Networks) cover vast geographical areas on the scale of a country or continent. WANs rely on telecommunications technologies to provide connectivity between remote sites, facilitating international corporate operations.

The most commonly used technologies are IP/MPLS (Multiprotocol Label Switching), PDH(Plesiochrome Digital Hierarchy), SDH (Synchrone Digitale Hierarchy), SONET(Synchronous Optical Network), ATM (Asynchronous Transfer Mode, etc.).

Networks are generally owned by an organization or company, and are therefore either privately operated or leased. In addition, Internet service providers use WANs to connect corporate LANs and customers to the Internet.

Global Area Network (GAN)

The GAN (Global Area Network) is a network infrastructure that connects different WANs on a global scale. A global network like the Internet is also called a GAN. This infrastructure is used by large multinational companies to manage operations across the globe, providing seamless and efficient connectivity.

Each of these network types plays a specific and essential role, together shaping the web on which a company's digital activity is built.
