Know how routers can choose a route suitable for you

This article describes in detail how to purchase a vro and how to select a vro suitable for your use. What are the differences between them? The following article will give you a detailed answer.

Currently, the most widely used Internet access method for domestic households and small and medium-sized enterprises is ADSL, while common ADSL Modem can only connect to one computer. If you need to connect to multiple computers, you need to use a switch or router, as the prices of vrouters continue to decrease, vrouters in the home market have basically replaced vswitches. I believe that everyone is familiar with the name of a router. However, for most users, it is not difficult to choose a suitable router.

Which of the following vrouters is more suitable for you?

The market has a wide range of router products, with prices ranging from tens to hundreds of thousands, or even tens of millions of yuan. What are the characteristics of these routers? What are their advantages?

First, let's take a look at the classification of vrouters. Routers can be divided into wired routers and wireless routers by transmission mode. Based on the Use environment and performance of the router, you can divide the router purchase into low-end, middle-end, and high-end. This may also be the most recognized classification method. What kinds of vrouters are suitable?

Low-end routers are also the most widely used by ordinary consumers. The routers used by ordinary households or small and medium-sized enterprises belong to low-end routers. The characteristic of these routers is that their packet exchange capability is generally not high, generally, it has only four lanports and supports simple filtering methods such as IP, MAC, and URL.

The middle-end router is suitable for large and medium-sized enterprises, Internet service providers, or municipal network applications in the industry network. When purchasing such a router, we mainly consider the port support and packet conversion capabilities.

High-end routers are mainly used in vrouters on the core and backbone networks with extremely high port density requirements. This type of routers are rarely seen by ordinary users. telecommunications service providers are mainly used to deploy various backbone networks to purchase these vrouters, when using high-end routers, performance factors become more important.

I briefly understood the classification of vrouters. Next I will discuss how to buy vrouters.

As common users see and use low-end routers, we will only discuss low-end router products.

For ordinary users, low-end routers now have a large market for both wired and wireless networks, which can be roughly half of each other. Therefore, we should first determine whether to choose wireless or wired routers. Then, based on the basic principles of vro selection, determine the products to choose.

Currently, most low-end wired routers use five ports (one WAN and four LAN). They are equipped with firewalls and support filtering methods such as IP, MAC, and URL. Most low-end wireless routers have two transmission modes: wired and wireless. With the development of technology, the speed problem restricting wireless routers has been greatly improved, the theoretical speed of the latest IEEE 802.11n standard wireless router can reach 300 Mbps, which can meet the needs of common users.

After reading the simple analysis above, someone may ask: Why don't we directly choose a wireless router? To answer this question, you must first understand the advantages and disadvantages of the wireless router and the requirements of the use environment. First of all, although the wireless router theory can reach a high speed of Mbps, the devices that need to be transmitted and received all adopt the latest IEEE 802.11n standard. Currently, few laptops come with this standard, the corresponding independent wireless network card price is too high. Secondly, the wireless signal of the wireless router may cause great losses when it is subject to external interference, especially for ordinary domestic users, the wall of the cement reinforced steel structure will cause a great loss of wireless signals, resulting in a significant reduction in the transmission distance and speed. Finally, we have to talk about the cost. At present, whether it is a desktop or notebook, wired NICs are integrated. Using a wired network can reduce the cost of purchasing the corresponding Nic. Currently, no wireless Nic is provided for desktops, A large part of low-end laptops are not equipped with wireless NICs. To use wireless networks, You need to purchase independent wireless NICs. It can be seen that the cost of deploying a wireless network is much higher than that of deploying a wired network, but it is not completely negative, currently, all wireless routers have built-in switch functions to support wired networks, which puts a lot of pressure on wired routers.

After reading the above analysis, we may be confused. What router should I choose? In fact, when purchasing a vro, common users need to consider the current and future needs. After all, it will take a long time for a vro. If you are mainly using desktops, you can choose a wired router if you will continue using the desktop for a long time. If you are using a desktop or a notebook without a wireless network adapter, you may upgrade it to a wireless network in the future, you can consider a wireless router. If you are using a notebook with a wireless network card and want to use a wireless network or get bored with a wired network, you 'd better choose a wireless router.
