Home Router Shopping Guide

With the heat of the family network heating, easy to use, but also to ensure that a certain Internet security of home broadband routers more and more by the home user reuse, as the home of the preferred device for sharing the Internet, such a wave, sharing the internet has become a real theme. Today's broadband routers need only an external IP address to connect more than one home computer to the high-speed Internet, save time and money, no longer as the previous configuration of a computer for proxy server sharing as complex. Today's routers are typically built with Full-duplex 4-Port 10/100m switches, in the case of less than 4 computers, can directly connect four devices to share the Internet, easy to set up a home network, can also connect the hub or switch to allow more computer equipment to share the Internet, you can also choose to use a wireless router to build a wireless LAN, Avoid the trouble of wiring.

With the continuous development and progress of network technology, the function of broadband router is also expanding. In the face of a variety of functions how to rationally choose the right to their own functions? We want to use the home broadband router application positioning, the application of positioning related to the performance of the router is the entire purchase process is the most critical step. For ordinary home users, the speed and performance requirements will not be too harsh, special features or other requirements are not too high, so the common low-cost broadband routers on the market enough to meet the needs of the general home network; for high-end home users, the choice of high price, A broadband router with a certain special function; If the mobile internet needs of the family to choose a wireless broadband router is more appropriate. Common home broadband routers we commonly used in the following functions, these are very basic and very practical functions.

1. Data channel function and control function. This is the router has two typical functions, the data channel function includes forwarding decision, backplane forwarding and output link scheduling, and so on, generally by specific hardware to complete the control function is generally implemented by software, including with neighboring routers information exchange, System configuration, System management and so on. On the basis of the same price, the function index of course is our choice object.

2. Firewall capabilities. Network security is currently the most concerned about, the built-in firewall in the router can play a basic Firewall function, it can block the IP address of the internal network, set IP address, communication port filter, can prevent hacker attack and virus invasion, Users do not have to spend extra money to install other virus protection devices to have a more secure network environment. Therefore, the firewall function is an important function of the home broadband router, because if the firewall does not have the security protection, the home network is affected by the virus invasion and the hacker attack the likelihood to increase, thus may cause the network paralysis, causes the user many trouble. The current router firewall features include anti-IP address filtering, URL filtering, MAC address filtering, IP address and MAC address binding, as well as some anti-black capabilities, security logs and so on. Through the router built-in firewall function, can set different filtering rules, filter to alien the network of all the abnormal packets, so that the internal network users can feel at ease on the Internet.

3. Virtual dialing capabilities. ADSL access to the Internet has virtual dial-up and dedicated line access two ways. The use of virtual dial-up users like modem and ISDN dialer, in the habit of using the same as the original way; users with dedicated line access can access the Internet as long as they are powered on. The so-called virtual dialing refers to the use of ADSL access to the Internet, the same need to enter a username and password (and the original modem and ISDN access the same), but ADSL connection is not a specific access number such as 16900, but through a special dial-up program with a specific network server to establish a connection. This function can more effectively protect users ' access to the Internet and make rational use of network resources.

4. DHCP functionality. DHCP (Dynamic Host Allocation Protocol) is a TCP/IP standard protocol that simplifies host IP address assignment management. It is safe and reliable to avoid the errors caused by manually setting IP addresses and subnet masks, and also to avoid the address conflicts that result from assigning an IP address to multiple workstations. Users can use DHCP servers to manage dynamic IP address assignments and other related environmental configuration tasks (such as DNS, WINS, gateway settings). Using a DHCP server greatly shortens the time it takes to configure or reconfigure workstations on your network, while setting the DHCP server to flexibly set the lease for the address.

5. Website filtering function. With this feature, you can monitor and record the Web site access for the entire network. Through the right group to manage the computer within the network, each user has their own permissions, which determines the network members to browse the scope of the site, not allowed to visit the site will be blocked, to give you a clean network environment.

6. Web interface Management. Since most of the home users lack the relevant network expertise, it is important to pay attention to router instructions when purchasing a router or ask the merchant if it is possible to provide web interface management, otherwise there may be some configuration or maintenance difficulties for home users. Chinese-language Router maintenance interface is more user-friendly, making the operation easier.

7. Internet access restrictions. Now the home network, usually in order to limit the children's Internet time and improper network applications, need to the child's dedicated computer access to the right to make appropriate restrictions, so in the purchase of routers need to pay attention to see whether the purchase of the router has this flexible configuration function (that is, the corresponding agent services).

8. Flow control function. It can allocate the network bandwidth, and use the optimized routing algorithm to balance the network load, so as to effectively control the congestion and avoid the network performance decrease due to congestion. This makes it easy for users to adjust the bandwidth of their downloads and internet computers so that the entire network slows down because of downloading.

9. Supports multiple connection modes. Now the network connection Way is various, the different connection way needs the different protocol support. Therefore, we can save a lot of trouble by choosing a router that supports a variety of protocols. Today's broadband routers generally support TCP/IP, PPPoE, DHCP, NAT, ICMP, SNTP protocol, basically can meet the family commonly used ADSL and fiber access mode.

10. Transmission speed. The speed of information transmission is often the most concerned about the user, so choose a good router transmission speed will become our users must seriously consider the problem. At present, 10/100mbps Adaptive router has become the mainstream, the general routers can provide all or part of the 10/100mbps port, simply provide 10Mbps port router has gradually faded out of the market. Gigabit Switch Router's optical interface speed can reach 622Mbps, 2.5Gbps or even 10Gbps, such a speed has been far away from the ATM switch in the back, but the gigabit core routers generally as the backbone of the enterprise network, and the price is much higher than the average home router. So choosing a general 10/100mbps adaptive router is enough to meet the needs of the home network.

11. Number of LAN ports and WAN ports. LAN port that is, because the number of home computers can not be too many, so as long as the number of LAN port to meet the demand, too much of the LAN port for the family is just a waste, and will increase unnecessary expenditure; Wan Port is the broadband network port, It is a WAN interface that is used to connect to an Internet network. And now the average home broadband users are not very high network requirements, so the router's WAN port generally only need one is enough.

Of course, special features are the area of concern for some home users with special requirements. Such as:

(1) If the user network to select the time to charge for the Internet, then the router in accordance with the action of the Internet to automatically connect and disconnect the Internet connection function is quite important. During the network connectivity, the Internet can be disconnected without automatic, click IE Browser again, can restore the Internet function. This can be a good control of the internet costs, save money.

(2) If you have a printer, you need to use the printer as a shared printer (LAN, all of the authorized computers can be called to print) users, you can consider to buy a printer with the mouth (and mouth) of the print server router products. However, this kind of product prices are often more expensive than the average home broadband routers, whether the choice depends on the specific needs.

Summary: Broadband routers on the market provide a wealth of functions, in addition to some of the commonly used basic functions and individual special functions, some functions like the DMZ, VPN and other functions for home users is basically not play a role. In short, for the purchase of home routers, function applicable on the line, there is no need to waste money, there is no need to let advanced functions vacant.
