RED CAN  What is it + Types + How to create ▷ 2020

A limited geographic area network, also known Campus Area Network, is a useful tool when you need to connect local area networks of the same organization.

Because of that, We have prepared this article so that you know what a CAN network is and what it is for in computing. In addition, you will find information on the main uses they have and which are the sectors that benefit from it.

But this is not all, too you will be able to read the difference between CAN bus and CAN networks for you to become a true computer professional. Check out.

What is a Campus Area Network and what are they for in computing?

A local area network brings together multiple computers and devices that connect with each other to share certain resources. In this way you can access the Internet, send a file to print and operate on files that are installed on another PC. This network works according to an architecture established by a computer expertThey can be stars, mesh or centralized, among others.

In the same way as a local network, also called LAN, brings together many devices, a Campus Area Network (CAN) groups several LANs within the same geographic area. In this way it is possible to share different elements, for example, cabling, routers and access points. The main characteristic of a campus network is that the LANs must belong to the same organization.

The clearest examples you can find are the networks of university buildings where students belong to a certain LAN, while teachers and the library are part of other LANs. But all these local area networks are included within the same network of a university campus.

From this it follows that a CAN network is larger than a LAN, but smaller than a WAN or Wide Area Network.

What are the main uses of CAN networks and what sectors benefit from it?

What are the main uses of CAN networks and what sectors benefit from it?

Being CAN a network based on the “client server” protocol, it is established as a criterion that the data becomes identified and encapsulated messages, which are accepted or rejected by the computers that requested the information.

From this it follows that within a Campus Area Network Resources can be shared with lower costs and information can be transmitted more quickly between the different nodes that compose it.

Thus, The sectors that benefit the most from this type of network are those organizations that need a geographic range in order to operate. and that at the same time they are composed of smaller networks (which would be the LANs) to be able to work between the computers and give meaning to the usual turn of their activities.

Examples of this would be a university campus, a company distributed in a large building, a hospital, a factory, and administrative personnel of a municipal government entity.

What are the differences between CAN bus and CAN networks?

What are the differences between CAN bus and CAN networks?

As we told you in previous paragraphs, a CAN network is a system that groups together several LAN networks and it is created within a certain geographic area. Its objective is to transmit the data by converting them into messages (thanks to the network producer) and then encapsulating them so that they are received by the client, that is, the computer, that requested the information.

To carry out this task, it must be done through a communication protocol, which is called Controller Area Network or CAN bus. That is why the first thing you should know is what a bus in computing.

A bus is a topology that is used as a pre-designed system to transmit data digitally thanks to a printed circuit. If you have ever opened a computer and seen the motherboard, you will have found capacitors and resistors soldered to a plate that has several copper drawings printed on it. This is what is called a bus in electronics.

Knowing what a bus is, you can now define what a CAN bus is. This is the standard protocol used to perform tasks, within the CAN network. Then it allows data to be transferred at a high or low speed with the fewest possible failures.

Finally, you should know that this system was created by the German company Bosch in 1983 and is based on a set of standards established by the ISO 11898 standard. While a CAN network can be designed according to the needs of entities that need to group LAN networks.

How can we create a CAN network and what components make it up?

 How can we create a CAN network and what components make it up?

To create a Campus Area Network the most important thing is to have within the same geographical area different sectors of the company or organization that are connected by cable to generate a round trip communication.

Then you will need to have different hardware that allow working with the network. Within these elements you can mention the routers, access points, switches, servers and computers. It will also be necessary to insert components that function as transmission protocols, where it will enter CAN bus that we mentioned before.

Once you have all these elements the first thing to do is connect the different local area networks with a central server, which will work as a producer to convert the data into messages.

After this it is necessary include the software that the network will use. Within these programs you will find the operating system and the application software, which will allow detecting the network cards of each node to be added within the CAN network.

When you have all these elements assembled The devices and computers to be used by the end user must be included. This stage is where printers and other peripherals that help make sense of the network connect.

After this point, it will be necessary to design and build the proxy, file, mail and authentication servers, among others. Having established all this, it will be convenient to include the TCP / IP model to connect the nodes to the Internet and thus finish the tasks.
