An edge network is a form of computer network. It is located close to the user and not in a central location. Edge networks consist of end devices or nodes (such as computers, smartphones and printers). They are connected together via technologies such as Bluetooth, WiFi, Ethernet or 5G.
This makes it possible to quickly share data and applications from an edge device via the local network. A central server is no longer needed for this.
The distance between users and the applications they need is reduced. Edge networks thus improve performance, reduce latency and increase available bandwidth. That is why they have become increasingly popular in recent years.
Setting up an edge network requires the use of a number of network, hardware and software components.
Routers, switches, hubs and access points, for example, are part of the required hardware. Edge gateways can additionally secure the edge of the network.
Protocols such as TCP/IP or routing algorithms such as OSPF software components are used within the framework of the software. This is what makes cloud computing possible in the first place, for example via SD-WAN. Security precautions must also be taken to protect the data from cyber attacks.
An edge network can be very useful for media streaming services, for example, as it reduces transmission time.
Similarly, edge networks are also used to optimise Internet of Things applications (IoT). The Internet of Things includes, for example, smart homes and networked factories.
Edge networks are typically deployed in business or corporate environments. But they can also be used for home networks or other smaller systems. The use of IoT devices is enabled via edge computing.
The technology allows users to connect quickly and securely to their applications and cloud resources. This is achieved through improved performance over long distances and a shorter latency. You are no longer dependent on a central server in the data centre.
