Everything about the router (what is a router)?
router
The use of routers in the Network has become commonplace Is. One of the main reasons for the widespread use of router is the need to connect a network to Several other Internet networks or other remote sites in the present age Is. The name given to the routers fits what they do: “Send data from one network to another.” For example, If a company has a branch in Tehran and another office in Ahvaz, It can be a line leased Exclusive, Which connects to any of the routers in the office. That way, any traffic that needs to be done from one site to another is done. Be realized through the router and filter out all other unnecessary traffic Bandwidth and related costs are saved.
Types of routers
Hardware routers: The above routers are the hardware that special software produced by Manufacturers are currently running only “on black box To We look at them. The above software provides routing capability for routers. It’s their most important and perhaps easiest task to send data from one Network to another Network is to do well.
Most companies prefer To use hardware routers because they are compared to routers Software has more speed and reliability. The following is an example that Shows the router. Cisco 2600 Series Multiservice Platform
Software routers have a similar function to hardware routers. Their main responsibility is to send data from one Net Network to another. A router Software can be a server NT, ، Be a network server, or a Linux server. All systems The proposed network agent has pre-installed routing capabilities.
In most cases, routers serve as firewalls or gateway Internet is used.
In most cases, A software router can not replace a hardware router because Hardware routers have the necessary hardware and are pre-installed, Which allows them to connect to a specific link VAN Of the type Frame Relay ، ISDN or ATM A software router such as a Windows server has several network cards, each of which is connected to a network. LAN Connected and other connections to networks VAN It will be done through hardware routers.
Example 1: Using a router to connect two networks and connect to the Internet
Suppose from a router as shown below to connect two networks LAN Used to each other and the Internet. When a data router through a network LAN And Or the Internet receives, after checking the source and destination address, data Sends a receipt to any of the networks or the Internet. Used in the figure below, the Networks are divided into two parts. دو Separate Network. Each Networkrkas a hub that has all the computers Networked to it. In addition to the above, the router used has The interfaces required to connect each Networkrko from one interface. It is no longer used to connect to the Internet. Thus, the router can send the desired data to the correct destination.
Example 2: Using a router on a network LAN
Suppose a router in a network as shown below LAN, Used. In the above model, each of the devices in the Networkrkith an existing router, such as one gateway Collide. Thus, each of the machines on the Network LAN That intends to send an Internet packet or any location outside the Network LAN Has the desired package for the gateway. The seThe router user gateway Has the necessary knowledge about sending data. When setting protocol properties TCP/IP An address for each of the machines in the Network IP To gateway Considered to be. The following figure shows how to use a router to access Internet users on the network LAN is showing :
Example 3: Using a router to connect two offices
Suppose we ask the router to connect two offices. Use the work of an organization for each other. For this purpose, each of the routers Available on the Networkrksing, a protocol VAN Like ISDN are connected. “Practically,” using a cable that by ISP Relevant, the possibility of connecting to the interface is provided VAN The router is provided. The signal goes directly to the Network ISP. Go to the corresponding interface at the other end of VAN. Another router is connected. Routers, able to support protocols VAN Numerous such as Frame Relay, ATM, HDLC or PPP, Are.
The most important features of a router :
Routers third layer devices reference model OSI Are.
Routers will not be able to distribute data unless planned.
Most major routers have their proprietary operating system.
Routers use special protocols to exchange information that is not essential to their data.
How a router works on the Internet: The path is created To exchange information between the client and the server. Traffic time is not constant and uniform and is commensurate with the existing traffic situation and The availability of the route changes.
The Internet is one of the masterpieces of humanity in the field of communication Is. By creating the right communication infrastructure, users worldwide will be able to send emails, view web pages, and send and receive Data files in less than a few seconds. Existing communication network Using all kinds of telecommunication equipment, hardware, and software, infrastructure Provides convenient communication for general Internet users. One of The main and important elements that most Internet users may not have seen before Is routers. Routers are special computers that send information messages to guide users to thousands of available destinations.
How to send a message
To understand the performance of routers on the Internet, let’s start with a simple example. When for one of your friends, one Email How do you send the above message to your friend? How to navigate the above message, which is only computer-friendly. You will receive it among the millions of computers globally. ?
Most operations involve sending and receiving a message by the sending computer. It is done by the receiver computer, by the router. Routers are special devices That allow messages to move across the Network.
To be aware of the router’s performance, consider the organization Takes that has its internal NetworkrkThe employees of the above organization each use the Networkrkccording to the type of work they do. In the above organization, several computer graphic artists are working with the help of computer case designs.
They design the comment. When a graphic designer files through the Network for The colleague sends, due to the high volume of the submitted file, most of the network capacity Occupancy and subsequent for other users, the Networkrkill slow down. The above reason is The impact of one user’s performance on all network performance for other users by nature; Ethernet networks are back. Each packet by A user in the above networks is sent to all computers on the Networkrkill be.
Each computer addresses the received packet to be aware of The destination will check the packet. The above approach in the behavior of Ethernet networks, Simplifies their design and implementation but at the same time expands the Network, and Increasing expected operations will reduce network efficiency. Organization In the above example, we decided to create two separate networks, Takes, to solve the above problem. Create a network for graphic designers and a second network for other users. The organization is considered. A single router is used to connect the above two networks and the Internet.
Does my developer need Ethernet sockets?
In this wireless age, Ethernet sockets may look a bit old. But some devices, such as printers and TV boxes, only support wired connections. Connecting these items or PC to the developer program via Ethernet gives you a more secure and faster connection than wireless.
However, connecting devices to an Ethernet developer will not be as fast as a wired direct connection to the router. The signal must still be transmitted via waves from your router to the extender.
What other features should I look for?
Most WiFidevelopers have a “web portal” offering a set of advanced features (some of which also offer a mobile app). It can be accessed through a web browser, phone, or laptop. Type in the address provided by the manufacturer – which is often printed on the printer itself or in the manual if it fails.
Some of these web portals allow you to manage a guest network with your name and security settings so that visitors can connect to the Internet without access to your local devices. You may also have access control, which lets you know exactly who can connect, while scheduling lets you disconnect at specific times – which might be useful if you do not want kids. Get online in the middle of the night.
Think about the physical features when choosing your extender. Most units plug directly into an electrical outlet, and some models are large enough to prevent the use of adjacent outlets. If the power socket is low and certainly not something you want to take for granted, a main input socket on the front can also be very useful.
