The data path through the internet

Internet is the tool of access to information that is probably the most used in the world. However, there are paths that the data we send and receive take to make the magic happen. This is what we will see below.

The use of the SD-WAN system is, therefore, an upgrade from outdated computer network frameworks of the past as they are detached from traffic management and hardware-based monitoring functions.

The structure
Firstly, we need to understand that the internet is a set of networks that interface with each other. Soon, networks will vary in size and reach, and the smallest and best known LAN's (Local Area Network) may be the giant WAN's (Wide Area Network).

The data travels from a sender to a receiver, in two ways: Wireless (without cabling) or wired.

Wireless technology sends our data through electromagnetic waves that propagate in the air. However, the wired network (optical fibers) sends our data through pulses of light.

The data path
The data cover distances that vary, from nearby points, such as access to a website hosted on a server in your city, to sites in other countries.

However, there are paths through which the data travels. These paths will be presented below.

Backbones

It is the backbone of the data paths, making an analogy, backbones would be the main highways and the distribution points would be the local roads. Therefore, they provide the connection between great distances, linking states and countries.

Let's take an example: when you send an email to a recipient, what happens is the sending of data (email) from the local network to the backbone, from the backbone to the recipient's local network.
