When you decide to hire a service Internet For your home or office, generally, what matters most to you is the speed and cost of it. But, beyond those parameters, also it is valuable to look at the type of device that includes the service. Since the latter are responsible for providing a better connection and facilitate the configuration of the service.
In this point, the famous come into play which, over time, have become the most recognized interconnection devices in the world. Taking into account that this popularity is due to the fact that they are the devices that Telecommunications providers make it easy for their customers to establish the connection to the .
But, although they are so popular and common, the truth is that many of their users still do not know what they are for, specifically. In addition, they do not know how it works or its importance and are unaware of the types of routers that exist up to now. So that, In this post, we will emphasize all this information.
What is a router and what is it for in a computer network?
Also known as a router or router, a router is defined as a device that has the ability to interconnect computers operating within the framework of a . So, basically, it serves to link computer networks and implement Internet access doors. In this sense, the routers of a computer network are in charge of establishing the route that will be allocated to each data packet within it.
Whereas, these devices they are completely autonomous and are connected to a port available on the modem. In this way, it achieves route network traffic to your connected devices. So, since, the router takes care of distribute the Internet between the different connected devicesare widely used everywhere because they provide the access to the network by the hand of the telecommunication service provider.
How do routers work and what is their importance within a network?
Although it is true, the basic operation of a router or router, consists of send the data packets through the most appropriate path, at any given moment. For which, it deals with storing the packages received and processing the information contained, both origin and destination. After that, it forwards the packets to the final router and this one takes care of deciding the next hop in favor of its routing table generated by establishing the shortest or most pertinent way to carry it out.
Thus, the router fulfills the task of connect multiple devices within a given network by managing all the traffic that circulates between the computers that are connected. Therefore, if you have more than two machines linked from a router, it is possible establish communications between each other and thus, the router will direct the packets to the correct destination. Now, in order to route traffic to a specific route, the router needs modem support to ensure that one of those routes is the Internet.
Considering that the modem is the only device that has the capacity to establish connection to the Internet on a computer network, since it deals with modulating and demodulating the signals that are between the world network and the computer. Therefore, when a router is connected to the modem, all the equipment connected to the router will have the possibility of sending packets to the Internet. Otherwise, they will be able to find other available paths to broadcast such packets, but these do not correspond to the Internet.
Types of routers What are they and how are they different?
At present, there are numerous types of routers in the world, due to the evolution of networks and the Internet. Therefore, they need certain functionalities or characteristics with which they can satisfy the needs of their users, correctly.
However, in the first instance, routers can be classified into two large groups that are:
- access routers: They are those routers used to join two networks, generally, the network of a telecommunications operator with the network of its client. Thus, their routing function is simple because they only need to exchange data between two networks. But, in addition, it contains proxy, , NAT and load balancing.
- distribution routers: Unlike access routers, these are intended for connect more than two networks. In this way, its main function is based on routing the existing data between the different networks to which they are linked. That’s why, are capable of processing a large amount of information and they use routing algorithms in order to get the most optimal paths depending on the classes of data they handle.
However, beyond this generalized categorization, other more specific types of routers are also handled.
Which, we mention below based on small classifications of great interest:
According to your connection
This is usually the most recognized segmentation when it comes to mentioning the types of routers out there. So basically refer to wired routers and wireless routers.
Next, we will detail:
wired router
They are the first routers to hit the market, so They are the oldest. Which, as its name indicates, are devices that They use cables to distribute the Internet signal between all local computers that are connected to the network. Today, They are almost out of use.. Since, they are only used in those large installations in which, in a mandatory way, cables must be used to cover a certain perimeter.
Wireless router
This type is also known as “mixed router” and, currently, it is the most used. Well, thanks to the fact that it works without the need for wiring, it is in charge of provide Internet through a WiFi connection and it has several outputs to guarantee excellent quality connections. Therefore, it also fulfills the functions of a wireless access point thread. For his part, there are several subtypes of wireless routers That is worth taking into account when purchasing one of them.
These are the following:
- 4G router: Are those devices that provide wireless Internet to their users without them being connected to a fixed line (telephone or fiber optic). Since, they use the signal 4G of mobile telephony for the signal by Wifi In the home. That’s why, It is used in rural areas, more than anything.
- Single band routers: Basically, they have the ability to operate at 2.4 GHz, which is characterized as the most common frequency, at this time. Thus, it can provide a speed of 450 Mbps.
- multiband routers: Unlike monoband, multiband routers have the option of working at a capacity from 2.4 GHz and 5 GHz. Therefore, they provide a higher speed of up to 1,750 Mbps and include numerous coverage ranges because they have more antennas.
According to your user
This is another of the most important classifications to segment the types of routers that exist today.
Next, we mention the two types of routers that exist, according to their user class:
- Routers for commercial use: Given their nature, they are routers that emit much more speed and power when routing the data packets. Therefore, they are useful to offer an optimal connection Wifi to a large flow of users in commercial configurations. Like, for example, in a shopping center or a hotel.
- Consumer Use Routers: As its name indicates, it is a device that has the ability to meet Internet requirements in a small environment (either a home or a business with small dimensions). Thus, they operate as a wireless access point to create a connection to the Internet and other locally configured devices.
Types of OSPF routers
Another classification of interest refers to Open Shortest Path First (OSPF) routers which, in Spanish means “Open the shortest path” and consists of a network protocol for hierarchical routing of interior gateways. In that sense, uses the famous “Dijkstra” algorithm when calculating the shortest path between two nodes.
However, this protocol uses special routers that manage to maintain topological information more complete than that of the perimeter in which they are located. Which, gives rise to the present segmentation in which several routers that are worth knowing are differentiated.
Next, we proceed to mention each one:
- internal router: Are all those routers that present their interfaces in the same area. Thus, they are characterized by being the simplest routers of the type OSPF.
- backup router: Basically, it refers to a router that is located in the backbone area. Being this, a generalization of a subnet.
- Edge Area Router: These are those routers in which the interfaces can be connect to various areassimultaneously.
- Autonomous system border router: It is a router that has an interface linked to another autonomous system or, failing that, a “external internetwork”.
