A limited geographic area networkalso known Campus Area Networkis 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 the CAN bus and CAN networks so that you become a true professional in computer science. Check out.
What is a Campus Area Network and what are they for in computing?
A local area network brings together various 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 expertcan be stars, mesh or centralized, among others.
In the same way as a local networkalso called LAN, brings together many devices, a Campus Area Network (CAN) brings together several within the same geographic area. In this way it is possible to share different elements, for example, cabling, 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 the students belong to a certain LAN, while the professors 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 Wide Area Network.
What are the main uses of CAN networks and which sectors benefit from it?
Since CAN is a network based on the “”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 make it up.
Therefore, The sectors that benefit the most from this type of network are those organizations that need a geographical breadth to be able to operate. and that at the same time they are made up of smaller networks (which would be the LANs) to be able to work between the computers and make sense of the usual course of their activities.
Examples of this would be a university campus, a company distributed in a large building, a hospital, a factory, and administrative staff of a municipal government entity.
What are the differences between the CAN bus and CAN networks?
As we told you in previous paragraphs, A CAN network is a system that groups several LAN networks and is created within a certain geographic area. Its objective is to transmit the data by converting it into messages (thanks to the producer of the network) and then encapsulating it so that it is received by the client, that is, the computer, which requested the information.
To carry out this task, you must do it through a communication protocol, which is called Controller Area Network or CAN bus. That is why the first thing you should know is what is 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 looked at the motherboard, you will have found capacitors and resistors soldered to a board that has several copper patterns printed on it. This is what is called a bus in electronics.
Knowing what a bus is, we can now define what a CAN bus is. This is the standardized protocol used to execute tasks, within the CAN network. Then it allows data to be transferred at a high or low speed, producing the least amount of failures possible.
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 the entities that need to group LAN networks.
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 geographic area different sectors of the company or organization that are connected by cable to generate a two-way communication.
Then you will need to have different hardware that allow you to work with the network. Within these elements we can mention routers, access points, servers and computers. It will also be necessary to insert components that function as transmission protocols, where the 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 serverwhich 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 the detection of the network cards of each node to be added within the CAN network.
When you have all these elements assembled it will be necessary to include the devices and computers that the end user will use. This stage is where printers and other peripherals that help make sense of the network are connected.
After this point, it will be necessary to design and build the proxy, file, mail and authentication servers, among others. Once all this is established, it will be convenient to include the to connect the nodes to the Internet and thus finish the tasks.
