How Krucial Routers Work In Internet Connection

How routers work (freepic)

YOGYAKARTA - Router is a network device that plays an important role in connecting various devices in a network. Have you ever wondered how the router works?

By using network protocols, routers set data traffic, direct data plans to the right destination, and allow various devices to communicate with each other.

This article will discuss in detail the understanding, the router work mechanism, from the basis functions to the advanced features it has.

Reporting from the Cisco page, routers connect computers and other devices to the internet. Routers act as dispatchers, choosing the best route for your information travel.

Routers can connect your business to the world, protect information from security threats, and can even decide which computers are more prioritized than others.

In addition, routers help you connect multiple devices to the Internet, and connect your devices to each other.

You can also use routers to create device local networks. This local network is useful if you want to share files between devices or allow employees to share software tools.

If you don't have a router, your business data won't be directed to the right place. For example, if you want to print a document, it will require a router to help send the document to a printer instead of a other computer or scanner.

Routing is the ability to forward an IP package (a data package with an Internet Protocol (IP) address from one network to another.

The router's job is to connect networks in your business and manage traffic within these networks.

Routers usually have at least two network interface cards, or NIC, which allow routers to connect to other networks.

Routers will search for the fastest data path between devices connected in a network, then submit data through that line. To do this, the router uses the so-called "metric value," or preference number.

If the router has a choice of two routes to the same location, it will choose a path with the lowest metric. These metrics are stored in a routing table.

The routing table, which is stored on your router, is a list of all possible paths in your network.

When the router receives an IP package that needs to be forwarded to another place in the network, the router sees the destination IP address of the package and then looks for routing information in the routing table.

If you manage a network, you need to get used to the routing table because it will help you solve the network problem.

For example, if you understand the structure and search process of a routing table, you should be able to diagnose any routing table problem, regardless of a certain routing protocol level.

For example, you may notice that the routing table has all the routes you expect, but the packet successors don't work as well as expected.

By knowing how to find the destination IP address of the package, you can determine if the package is forwarded, why the package was sent elsewhere, or whether the package had been discarded.

When making changes to the network routing option, then you go to your router to access the software. For example, you can go to the router to change the login password, encrypt the network, create port replacement rules, or update the firmware router.
